any other engine

the 4.3L V6 is probably the easiest swap into a boat with a 3.7L. It will give similar performance. The 5.0L and 5.7L V8's are probably the best performance per $ as the 4.3L V6 is not a cheap engine. Either one will require some glass work to build stands for the motor mounts

under repairs forum page five you will see a thread that reads how to clean a bilge. that shows a clear picture of a V-8 chevy motor bed. i could also give you all the dimensions needed for the conversion. mine V-20 was factory original 5.7 gm i/o mercruiser.

I have the 4.3 litre Chevy v6 in my 1991 v20 cuddy. It performs nicely.

ok is yours a cast iron block and heads how does it handle the weight i the back does it sit low in the water

yes cast iron block,heads.intake and exhaust manifolds am sure there is a little more weight involved here but trade off for more power is worth it . i have a stock 260hp . but as you see on this site what happens when you re-work a 5.7 with all the correct stuff. the best part is its proven. it passed the lie detector test gps speed in mph!!!!!!!!!!!!!!
