What one reference says Sea-Doo did
A year-by-year Sea-Doo line from 1968 to 2027, restated from a single enthusiast reference and graded accordingly. The engine and hull tables and the nine service notes are the part worth your time: they decide what is in your ski and what it costs to fix.
| 1972 | 1973 | |
|---|---|---|
| Came out | October 1972 | |
| Sold as | 1973 model year |
| 1986 | 1987 | |
|---|---|---|
| Came out | November 1986 | |
| First Yamaha row in the model reference | WaveRunner (WR500), 1987 |
In both records the second year falls one year after the first, so two sources that count the same machine differently can disagree by exactly that much.
How we know: The dated milestones on Where the sport came from, and the model reference's own rows.

The whole span in rows of ten years. The dashed squares are years this publication never mentions; every other square links to its year further down.
How we know: This timeline's own entries, and the years it declares it holds nothing for.
The 20 years with no record, as a list
1970, 1971, 1972, 1973, 1974, 1975, 1976, 1977, 1978, 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 2023
Two different kinds of hole, and they should not be read the same way. 1970 to 1987 is Bombardier out of the personal watercraft business entirely after the 372 recall, an eighteen-year absence covered on the origins page, so there was nothing to record. 1988 and 2023 are holes in the source: the origins page dates the return to 1988 and the model reference carries a 1988 SP, but this page starts the modern line at 1989, and 2023 appears in that page's own year navigation with no section written under it, so a 1988 or a 2023 Sea-Doo is simply not covered here and has to be looked up somewhere else.
Year by year
58 of the 79 Sea-Doo model entries below link to that machine's page in the model reference; the other 21 are plain text, because the reference holds no single machine under that name for that year. They carry 60 different names, because some names are listed in more than one year.
-
1968
-
Sea-Doo 320
Designed by Clayton Jacobson II, built by Bombardier. Berkeley jet pump driven by four belts. A 7.5 ft fibreglass hull with flotation foam, and a lot of shared Ski-Doo parts: removable tank, metal bars, pull start, bench seat. Roughly 25 to 30 mph. The air-cooled engine sat in a closed hull and overheated chronically, which is the fault that defines it.
JetSkiPlus claims: the first personal watercraft, and the first sit-down PWC, before Kawasaki's stand-up
-
-
1969
-
Sea-Doo 372
Redesigned hull and keel and a larger pump. Hot-start explosions triggered a recall that reglassed hulls, sealed vents, moved the recoil starter under the seat, waterproofed the rectifier, deleted the bilge blower and reverse and redesigned the ignition switch. Production ended late in the year and the remaining units were ordered destroyed.
-
-
1989
A new hull and top cap, with the engine, electrics and propulsion reachable from under the seat. This is where the modern line starts.
-
1990
-
JetSkiPlus claims: the first three-passenger Sea-Doo
JetSkiPlus claims: the first Sea-Doo with reverse
The GT arrives on a new smooth-bottom hull. Single carburettor on the yellow 587.
-
-
1991
The XP arrives as the fast one. The SP gains a grab handle.
-
1992
The yellow 587 is phased out for the white one.
-
1993
-
Single carburettor, bronze pump, electric trim, rounded styling.
-
The previous year's XP sold on as its own model. That pattern repeats every year to 1998, which matters when identifying one.
-
An SP with a stainless impeller and a new exhaust.
-
The luxury three-seater, dual carburettor, fuel gauge.
-
GTS
-
SP
The 657 joins the white 587, and the range roughly doubles.
-
-
1994
-
1995
-
The X4 hull arrives here with adjustable trim tabs, and the 800 brings RAVE valves. This is the combination people still hunt for.
-
Single seat with a suspended seat, built against the WaveBlaster.
The 717 at 85 hp and the 787 at 110 hp both arrive. The GTX moves to the 657X.
-
-
1996
-
Electric trim.
DESS security arrives on the GTX, XP and GSX, and with it the dealer-only lanyard. New ignition and electrical system, LCD information gauge. The GTX hull and top cap are redesigned around the 800 with a two-piece seat. The 657 is dropped.
-
-
1997
-
The hull switches from leaning out to leaning in: engine forward, suspended motorcycle-style seat off the HX, about 90 lb heavier. Slower off the line, faster at the top. Whether this was an improvement is still argued about.
The white 951 debuts at 135 hp and has a reputation for reliability trouble. The 587 is dropped. The 1996 GTI is relabelled GTS and a new GTI becomes the mid-tier three-seater on the GTX hull.
-
1998
-
The 800 RFI.
JetSkiPlus claims: the first fuel-injected Sea-Doo engine
The 951 is revised and painted silver. The XP, GSX and GTX take it with a Limited badge. The SPX is lightened into the quickest X4 hull there was. The HX is dropped.
-
-
1999
The last year of the X4 hull and of the SPX. Otherwise colours and graphics.
-
2000
-
A larger, heavier two-seat platform, offered carburetted and direct injected. It becomes the basis of the 2004 RXP.
-
Four seats, the largest personal watercraft in production, built against the Yamaha SUV. Discontinued after four years.
The 947 DI arrives at 135 hp with better emissions and economy. The SPX goes and the X4 hull with it. Limited is dropped from the 947 models.
-
-
2001
-
A limited-production race RX on the carburetted 947 with performance parts, reported as the fastest stock Sea-Doo to that point.
A holding year: no engine or major feature changes. A new GTS appears as a de-featured GTI.
-
-
2002
-
1494cc three-cylinder, naturally aspirated, closed-loop cooling, 785 lb. New engine management with a separate ECU alongside the MPEM.
JetSkiPlus claims: the first four-stroke Sea-Doo
Off-power assisted steering arrives on the GTI LE, GTX 4-TEC and GTX DI. A new hull and top cap for those three, with stadium rear seating and sealed front storage.
-
-
2003
-
GTX 4-TEC SC
-
GTX Limited SC
Supercharging arrives at 185 hp, both models over 750 lb. The XP and LRV move to the 951 DI.
-
-
2004
-
790 lb dry, just under 70 mph, on a faster-spinning supercharger. This is the first year of the ceramic clutch washer problem, so read the service note before buying one.
-
WAKE
A GTX 4-TEC with a retractable tow pylon and removable board racks.
Four of eight models are now four-stroke.
-
-
2005
-
The three-seat RXP at 869 lb. Gives up very little top end and is much better in rough water.
-
Five riding positions: kart, knee, stand-up, stand-up with a fixed handle, and motorcycle. The premium version gets the 800 RFI.
The XP is discontinued; the page counts its run as 13 years from 1991. The GTX Limited SC goes to 215 hp.
-
-
2006
-
A serious change in how they are built.
JetSkiPlus claims: the first Sea-Doo hull not built in fibreglass, every one until then having used it
-
Adds a speedometer, mirrors and a boarding ladder.
The LCD gauge is now married to the ECU, so a replacement needs a dealer or the ski will not start. The 3D swaps the 800 RFI for the 947 DI.
-
-
2007
The MPEM is eliminated and its functions move into the ECU, which changes diagnosis and parts lookup from here on. The RXP and RXT get a redesigned top cap with wider, repositioned bars. The GTX Supercharged is dropped, and so is the 3D, ending the two-stroke line.
-
2008
-
RXP-X
0 to 50 mph in 2.9 seconds. X racing bars, seat and traction mats.
-
RXT-X
Trim on a three-seater.
JetSkiPlus claims: the first year trim is available on a three-passenger Sea-Doo
-
Gains 200 lb of removable water ballast.
The 1503 at 255 hp: better supercharger, better external intercooler, new fuel management. The ceramic clutch washers become metal, which ends the engine-destroying failure but not the wear item.
-
-
2009
-
RXT iS
Suspension, plus fly-by-wire throttle, electronic brakes and high-performance trim on a CAN bus. Powerful and expensive to fix.
-
GTX Limited iS
A two-part top cap and a lot of electronics arrive together. The WAKE 155 moves to the composite hull and loses its standard ballast tanks.
-
-
2010
The RXT-X, RXT iS and GTX iS go to 260 hp and the electronics spread across the GTX and RXT ranges plus the Wake 215. The RXP-X stays without them.
-
2011
-
GTI Limited
Only the RXP-X 255 and the GTS Pro are still without the electronics package.
-
2012
-
RXP-X
The T3 hull, with the locking ergonomics, angled footwells, adjustable sponsons, a boost gauge and five-position trim tabs.
-
A lighter, cheaper muscle craft on the GTI composite platform.
-
GTX iS 215
The electronics package is standard across the range. Fifteen models, up from fourteen.
-
-
2013
A holding year. The RXT iS 260 is dropped and the range goes back to fourteen models.
-
2014
-
Resets the bottom of the range. The page gives the Spark no engine figures.
The composite-hull models gain about 35 lb, from 755 to 790 lb dry, almost all of it in the bare hull. Expect slower acceleration and a lower top end on them, with the GTR 215 worst affected.
-
-
2015
Essentially colours. The one change that matters is DESS moving to radio frequency, which fixes the intermittent-contact problem the contact version had.
-
2016
The 1630 arrives: longer stroke, more displacement, higher boost, a larger maintenance-free intercooler, larger injectors, forged pistons and an extra heat exchanger. It needs 91 octane. Second-generation electronic braking is 20 percent faster.
-
2017
-
The cheapest X model.
The 1500 HO ACE 230 replaces the 215. The GTS and GTI move to the Polytec hull and the 900 ACE HO, losing about 150 lb and dropping from 130 to 90 hp, which costs about 6 mph at the top and nothing at all to 30 mph. The whole line moves to a bolted hull and deck with a gasket, so the top deck comes off.
-
2018
ST3 hull
Closed-mould construction with a multi-layer thermo-film skin rather than gel coat, which is tougher. Deep-V, 1.2 in wider, fixed trim tabs and new sponsons. Fitted to the GTX, Wake Pro and RXT ranges.
The 1503 260 is deleted. Storage, a clear glovebox lid with a USB charger, a wider boarding step and external drain and flush fittings arrive with the new hull.
-
2019
-
A new category on the ST3 hull: an 18.5 gallon tank, a fitted sounder and transducer, rod holders, a detachable cooler with a cutting-board lid and a rear platform extended by nearly a foot.
-
GTI 130 Pro
A rental unit: detunable to 99 hp, heavy-duty driveline, uprated electrics.
A quick-attach accessory system arrives that fits many 2011 and newer skis. New instrumentation on the GTX, RXP, RXT and Fish Pro with an owner-resettable service reminder and live fault codes. The 900 ACE gets new injectors, and a new jet pump seal design appears that retrofits to older models.
-
-
2020
-
GTI
Polypropylene with fibres, lighter and more scratch resistant than fibreglass. An inch wider, with everything lowered for a lower centre of gravity.
The 170 hp 1630 ACE replaces the 155 hp 1503 in the GTI SE, GTX and Wake. A new display, and a speed regulator and slow mode as standard on the GTI SE, GTR and Wake.
-
-
2021
-
An all-new deep-V hull with a mid-hull shark gill and X-sponsons, new ride plate, intake grate and polished stainless impeller. 67 lb lighter, 10 percent better power to weight.
-
Rental specification on a fibreglass ST3 with heavy-duty wear parts.
A debris-free pump arrives that backflushes from a handlebar button, standard on the Fish Pro 170 and GTX Limited 300 and optional on the GTX 170 and 230.
-
-
2022
-
On the GTI SE 130 platform, for the occasional angler.
-
More fishing equipment and better in rough water.
Otherwise colours and accessories.
-
-
2024
-
300 hp on the nimble Polytec hull, with the racing seat and footwell wedges and launch control. Roughly 4 seconds to 60 mph.
1630 ACE 325
Forged rocker arms, coated pistons, iridium plugs and a supercharger spinning to 100,000 rpm.
JetSkiPlus claims: the most powerful engine Sea-Doo has ever offered, as of 2024
Hydraulic steering dampers and carbon-fibre hoods appear on the top models. The FishPro range gains a detachable chartplotter.
-
-
2025
-
A one-year limited edition. The largest screen in the range, a modular 360 degree swivel pedestal seat, an extended rear deck with a cooler and a livewell, two batteries and integrated anchoring.
325 hp, the hydraulic steering damper, pop-up docking cleats and the large touchscreen spread to the GTX Limited, Explorer Pro and RXT-X. Livewells, GPS module positions, battery brackets and hull fittings are all revised.
-
-
2026
XCU engine control module
The electrical system moves onto a new module with new harnesses, a new security system and tighter audio and navigation integration. Dealer diagnostics move to a new generation of tool at the same time.
The 1630 Rotax family gets redesigned long blocks, cylinder heads, connecting rods and intake, plus new impellers and wear rings. Larger touchscreens and new handlebar controls spread across the range.
-
2027
-
RXP-X Senna 350
1,991 units worldwide, for Ayrton Senna's third championship year, carrying a "1 of 1991" plaque rather than individual numbering.
1630 ACE 350
Replaces the 325: a 75.5mm compressor wheel up from 72.5, a rev limit of 8,500 up from 8,250, and a stronger connecting rod and rod bolts. 0 to 60 mph in 3.1 seconds against 3.4.
A redesigned stator with repitched vanes cuts cavitation and adds thrust, a new ride plate lifts the bow and a new intake grate improves pump ingestion. The 350 goes in the GTX Limited, RXT-X, RXP-X and RXP-X Senna, and the GTX Limited loses the debris-free pump in the swap. The GTR-X stays at 300. The FishPro Scout is discontinued.
-
Engines
Which engine went into which Sea-Doo craft, and the years JetSkiPlus gives for each. The sizes are that publication's figures, and it is the only source behind this table.

Things that decide a repair bill
Each of these is one source's account and none has been verified against a service manual. They are worth reading anyway, because knowing to check costs nothing and every one of them can be confirmed against the craft in front of you.
-
Ceramic supercharger clutch washers destroy engines
2004 to 2007 supercharged 4-TEC
The clutch washers are ceramic and they shatter in service above about 35,000 rpm, sending fragments through the engine. Metal replacements are the fix and BRP changed the design for 2008. If you are buying one of these and nobody can tell you whether it has been done, assume it has not.
-
The washers still wear after the redesign
2008 onward supercharged
Metal washers do not shatter but they do wear out. The source gives an inspection interval of 75 to 135 hours depending on how hard the ski is ridden, which is short enough that it belongs in a maintenance plan rather than in a list of things to get to eventually.
-
DESS lanyards need a dealer
1996 onward
The security system means a replacement lanyard has to be programmed with BRP's dealer tool. A lost key is a dealer visit, not a spare in a drawer, and that is worth knowing before you buy a ski with one key.
-
The gauge is married to the engine control unit
2006 onward
From the new GTI platform the LCD gauge is paired to the ECU. A gauge off another ski will not simply fit: it has to be married by a dealer or the engine will not start. Budget for that before buying a used cluster.
-
The MPEM is gone
2007 onward
Its functions moved into the ECU. That changes both diagnosis and parts lookup for anything from 2007, and it means guides written for earlier skis will send you looking for a module that is not there.
-
The suspension and iControl skis are expensive to repair
2009 onward iS and iControl models
A two-part top cap and a CAN bus full of electronics. The JetSkiPlus Sea-Doo reference puts the iBR and VTS unit at around $900 against roughly $300 for the older VTS alone. None of that makes them bad skis; it makes a cheap one a different proposition from a cheap carburetted one.
-
91 octane minimum
2016 onward 1630 ACE
Not a recommendation. The engine was specified around it, so running lower octane is a decision about the engine rather than about the fuel bill.
-
The jet pump seal redesign fits older skis
2019 onward, and retrofittable
The new seal design is available as a kit for earlier models. That is the rare case where a later part is a straightforward improvement to an older ski rather than a compatibility problem.
-
2026 breaks diagnostic and harness compatibility
2026 onward
The electrical system moves to a new engine control module with new harnesses and a new security system, and BRP's dealer diagnostics move to a new generation of tool. Anything crossing that line, harnesses, security parts, diagnostic access, needs checking rather than assuming.
- One source, and not a manufacturer
- Every other reference on this site that carries this much detail is either a manufacturer document or two sources agreeing. This is neither. It is detailed, internally consistent and written by somebody who plainly knows the machines, and it is still one page by one author with no second opinion behind any figure in it.
- The service notes are the reason this is here
- Nine of the entries below decide a repair bill rather than a purchase: the ceramic supercharger washers that destroy 2004 to 2007 engines, the gauge that is married to the ECU from 2006, the DESS lanyard that needs a dealer, the 2026 move to a new engine control module. Those are worth having even at one source, because knowing to check is most of the value and none of them cost anything to verify against your own ski.
- What has been left out
- The source carries model-year pricing, colour names and the author's own riding opinions. None of that is restated here. Pricing goes stale, colours are not a part number, and the opinions are the part of that page that is genuinely its author's work rather than a fact anyone may restate.
- Where the model reference disagrees with this page
- A pointer for the model reference, not a correction here. This page prints the 2002 and 2003 GTX 4-TEC as 1494cc where the model reference carries 1503; the 1997 GSX Limited as 951cc and 135 hp against 947 and 130 hp; the 2006 GTI as 1494cc and 130 hp against the 717; and the model reference carries the 657 and 587 engines for 1997 to 2002 where this page ends them in 1996 and 1997 respectively. Which publication is right is not settled by either of them.
8 claims on this page are JetSkiPlus's own, marked as such wherever they appear. Other timelines · Model Reference, where fitment lives · Where the sport came from
Changes to this timeline
- 2026-10-01: Seven engine spans were corrected against the page's own year headings, so the white 587 is dropped for 1997 rather than after it, the 657X ends in 1995, the 717 runs to 2005, the silver 947 ends in 2002, the 1494 4-TEC runs to 2019 under the name 1503 from 2018, the 185 hp supercharged 4-TEC runs 2003 to 2006 and the 255 hp 1503 to 2011.
- 2026-10-01: Two displacements the page never prints were blanked, the 899cc on the 900 ACE and the Spark and the 1494cc on the 1500 HO ACE, and the 900 ACE row now starts in 2017 with the 60 hp noted as not printed, because the page does not describe the Spark's engine.
- 2026-10-01: The 1630 ACE 130 is dated from 2021, where the page first prints it, and the Polytec hull's 2017 to 2019 years are given for the GTS and GTI alone, the Spark's use of it being undated on the page.
- 2026-10-01: Five firsts the page claims moved from this record's notes into the attributed lists, the 1990 GT's three seats and reverse, the 1998 800 RFI's fuel injection, the 2006 GTI's non-fibreglass hull, the 2008 trim on a three-seater and the 2024 1630 ACE 325's output, and the engine and hull tables now say the page calls the 1494 4-TEC the first four-stroke, the 800 RFI the first fuel-injected and the GTI composite the first non-fibreglass hull, so none renders as this site's own claim.
- 2026-10-01: The 1968 Sea-Doo's first is no longer called mass-produced, a word the page does not use, and the 2005 line counts the XP's run as thirteen years from 1991, as the page does, rather than fourteen.
- 2026-10-01: The scope note now gives the page's engine figures by year, 951 for 1997 and 947 from 1998, 1494 for 2002 to 2007 and 1503 from 2008, where it had said the page carried 951 and 1494 outright, and a new caveat lists where the model reference disagrees for the model reference to settle.
- 2026-09-30: The service note on the iBR and VTS unit names the JetSkiPlus Sea-Doo reference as the source of its price figures rather than calling it the source.
- 2026-09-10: The scope note gained the sentence that this page's engine sizes are the publication's own and differ from the model reference's, 951 and 1494 here against 947 and 1503 there, with neither checked against BRP.
