I just picked up a 78' Chapparral 244 that has a 454 engine and Merc
Alpha outdrive system. I know the Alpha is not rated for more than 300
hp and should not be used with a 454. Does anyone know of someone that
has run a chevy 350 instead of a 454? And if so, how does the boat do
as far as gas milage and performance? The boat is approx. 4000 lbs, so
I really don't know if a 350 will push it as well as I would like.
