If you're willing to spend the money on the engine it shoul dnot be too bad.
If you're doing it yourself you might consider getting a v6 out of a wreck
and converting it for marine use. That would help wiith the costs a little.

I have a 1983 Grady White Seafarer 22" IO. The engine is the old Merc
Cruiser 488. 4 cylinder 188 hp. FWC. This motor is just about done and I
am
considering repowering with a Mercruiser 4.3 L V6 carburated 190 hp. Does
anyone have any experience with this job? Any problems or major pit falls
I
need to watch out for? Thanks.
