My old boat has a Mercruiser 120 which I have discovered is not going to run. The boat sat around for years and it is too long and boring a story to explain why. Low compression in 3 of 4 cylinders. Possible freeze damage IMO.
I want to Re-Power, but the 120 block is no longer manufactured and hard to find used.
So I have these choices for repower:
1) Replace the entire drivetrain with a 3.0 or 4.3 Mercruiser set-up (Engine, Stern bracket and outdrive). I say all three items because I was told today by a marine repair facility that my 120 engine accessories are not compatible with the 3.0 Mercruiser.
2) Hang an out-board bracket on the stern and buy an outboard set-up
3) Find a re-buildable GM 2.5 liter (Mercruiser 120) and re-build. Near impossible it seems.
If you have done any of these options to your boat or are a marine mechanic, what should I have to pay for these options?
Thanks for opinions in advance!
