Aye, and that's half the reason I now have a Clamshell..... 110Kg rated transom, 85Kg engine. I've even got capacity for an aux!
(which, incidentally, is a 13Kg (fuelled) 4Hp of 1974 vintage. How heavy is a 4Hp these days?) My entire setup clocks in at 420Kg fuelled.
Another Q that I should have asked before - how old are the boats you are talking about? I'll take my transom as an example - 110Kg rated. Not much I can actually hang on that at 60Hp, even in the 2- stroke arena. But then I look at all the old broures of the late 70s / early 80s. Most engines of that size were 2 cyl premix jobs, and power trim (another few Kg) was a very expensive optional extra if it was even offered at that size. 110Kg capacity was well more than enough. Not much later after my hull was built everything was 3 cyl and had autolube. My hull was redesigned slightly & renamed the Attaque. Transom now rated to 130 odd KG to handle all the extra weight....
Now, drag that observation into 2012. Sometime about 10 years ago a similar problem was had when these "lardy 4- strokes" appeared - do a search on here for 4 strokes & searider SR4s.
