A couple years ago when I was shopping for a 9.1, I had 3 boats surveyed and collected info on several more. The earlier hulls had the lower-rated Yanmars, the later ones had higher ratings. Recently the Mack Boring people (Yanmar east coast distributors) and also my surveyor, confirmed my suspicion -- Yanmar periodically upgrades their engines, and S2 installed whatever was being sold by Yanmar at the time of the build. S2's initial production had a 13 hp 2GM as the standard engine. In 1984-85 Yanmar redesigned the 2GM to a rating of 16 hp or so. Today Yanmar's 2GM engine is rated a few more hp than that. The 3GM(F) that was installed in my boat in 1985 (#094) has a rating plate showing 21 hp. Today the successor to that engine is rated about 27 hp. |
