What it made and sold

1996, 2001 and 2018 · Confirmed

Magazine tests and builds name Solas impellers. Personal Watercraft Illustrated's test of a modified 1995 WaveRaider 701, captured in 1996, used a Solas "K" (15/19) impeller, one of two parts its kit maker did not make; the magazine's report on a Stage II kit for the Yamaha GP1200R, captured in August 2001, says a Solas Concord 13/19 impeller came with the kit; and The Watercraft Journal's 2018 report on a GP1800R build names a Solas 160 mm Concord 13/20 impeller.

Sources: PWI 1996 Riva WaveRaider test; PWI online Riva Stage II 2001; Watercraft Journal RIVA GP1800R 2018

1996 and 1997 · Confirmed

Group K, in comments on magazine articles of 1996 and 1997, names Solas impellers by letter pitch, among them the I, J and Xo, and notes under a 1997 issue that no Solas "K" pitch then existed for the 1100 and 1200 pump, the next steeper after the "J" being the "X1".

2009 · Confirmed

US patent 7,794,294, granted in 2010, lists among its references online catalog pages of 1 September 2009 titled as covering Solas intake grates, beside R&D Aquavein grates and those of other makers.

Sources: US patent 7794294

Likely

The Watercraft Journal printed on 22 January 2025 the association's result on a proposal to allow any aftermarket pump in the Ski Modified class: the rule was not changed, and the association said it had not had any propulsion pump submitted for approval other than the Solas model.

Patents and trademarks

1987 and 1988 · Confirmed

The US trademark register records the SOLAS mark for marine propellers, filed on 7 December 1987 and registered on 6 December 1988, owned by Solas Science & Engineering Co., Ltd., a Taiwan corporation, and renewed since. The registrant claims first use on 1 April 1987.

Sources: USPTO record serial 73699150

1995 and 1998 · Confirmed

The same owner applied for two marks whose goods were jet pump systems and their parts. JETPRO, filed on 15 September 1995 for jet pump systems and parts such as intake grates, impellers, stators and nozzles for watercraft, boats and aircraft, was abandoned in 1997. GOLD PRO, filed on 11 June 1998 for marine propellers and impellers and for jet pump systems for watercraft, boats and aircraft, was abandoned in 2001.

Sources: USPTO record serial 74729508; USPTO record serial 75500174

2005 and 2006 · Confirmed

A second SOLAS mark, filed on 16 August 2005 and registered on 7 November 2006, covers jet pump systems consisting mainly of driving shafts, intake grates, intake tracts, impellers, stators and jet nozzles for marine vehicles, and claims the 1987 registration as the same owner's. The registrant claims use in commerce from 19 September 1998. The register's words are marine vehicles, not personal watercraft.

Sources: USPTO record serial 78693648

2006 and 2007 · Confirmed

US patent 7,270,583, High efficiency watercraft propulsion system, filed on 28 November 2006 and granted on 18 September 2007, names Solas Science & Engineering Co., Ltd as assignee and Yeun-Junn Lin as inventor. It claims an impeller set in a concavity formed in the hull, with a stator, a nozzle and an intake grate.

Sources: US patent 7270583

Likely

Seven earlier US patents, filed from 1990 to 1998 and granted from 1992 to 1999, print no assignee: an impeller, two motorboat impellers, a water inlet foil grating, two stators and a propelling system with an adjustable gap between impeller and stator. Four print the inventor as Yeun-Junn Lin and three as Solas Y. J. Lin, whom the archive reads as the same inventor by the initials and the printed city, an inference. Reading them as Solas's work rests on the inventor's name and the 2007 assignment, also an inference.

The business on record

2005 · Confirmed

The association's associate member directory of 9 March 2005 lists Solas among its corporate members, with the web address solas.com, the address at which the company publishes its present profile; the association's associate members page, stamped 2017, lists it again.

Sources: IJSBA associate directory 2005; IJSBA associate members page

Likely

The company's own pages say Solas was founded in 1985 by Dr. Solas Y. J. Lin, whom the archive reads as the inventor Yeun-Junn Lin by the initials, an inference. Its About page captured in October 2015 describes outboard and stern drive propellers; its present profile, under the company's corporate name, adds impellers for personal watercraft, an intake grate and a jet pump system. These are the company's own words.

What the archive has not read (3)

• No registry or period document dates Solas before its trademark application of 7 December 1987, which claims first use on 1 April 1987, so the 1985 founding stays the company's claim (searched the archive's mirror and research cache, 2026-10-16). Taiwan's company registry was not searched.
• The printed patents were not read; their subjects are given from the titles, abstracts and claims in USPTO's records. Google Patents, queried on 6 October 2026, lists 68 documents for the assignee Solas Science and omits US 7,270,583, so it gives no count that can be used.
• The association's own text of its 2025 rule result is not held; the result is read as The Watercraft Journal printed it (searched the archive's mirror and research cache, 2026-10-16).
