TowerOfPower Mercs were notorious for putting out more power that the sticker showed, at least in my experience.

hmmm I sure hope you're right.... I figured my old motor to be about equal to a modern 90 hp.

I guess the gps will tell the story... I've pretty much decided not to mess with this particular j-rude... I'd like to get more power (of course) but I wand mpg's and I don't think an old crossfllow j-rude would be even as good as my crossflow merc???

How come there is a difference in horsepower over the years. Isn't it rated at the prop? Or are our hourses bigger now than they were in the late 80s.

The engine in the pic is of a late 70's engine which is flywheel rated. In 86 when the ywent to propshaft ratings, this same 200 went down to a 150 XP.
