MARINE INBOARD VS. REGULAR SMALL BLOCK

[wendell]

Thanks for the info. The goal is for this boat to cruise between 25-30 and be as fuel effient as possible while sticking with a carb. I figured that the low rpm torque of a 383 would be a good fit. Conversely, I bet a ZZ crate long block from GM would get us to the same goal.

Last I heard, the boat and her owner had been sitting behind a rolled over semi for 2 hours and the highway patrol were predicting another 4! Fun way to spend the night.

I had a friend who is also a marine mechanic who put a car motor in for a guy and it took forever to get the rpm's and it running right, he swear's he would not do that again.

the GM HT383 engiine should be perfect for use in an inboard aplication, its tailored for a flat tourque curve( just what you want in an inboard engine), can't understand why Mercury continually builds its own 383 out of 5.7 engines rather than use the HT383
