I am considering getting a newer motor for my boat. I am currently running a 1988 90hp Merc on a 16' Lund that is rated for 90hp.
I have read that in the 90's the reference for a motor's horsepower was changed. Something like motor horsepower used to be measured at the powerhead, but is now measured at the prop? Therefore because of efficiency, an older 90 hp is not comparable to a newer 90hp, and the newer 90hp would have a lot more power than the old one.
I am ok with the speed on my current outfit, it is just a major gas hog, is cold-blooded, and I'd like something more dependable. So, I was thinking that maybe a newer 70hp (or maybe even 60hp) would be similar? Friends and relatives run similar (but newer) boats on 60 hp with the same speed as I can. I would guess their setups are lighter than mine. And - you don't see too many 16-footers rated for 90hp these days.
