Good day all.
My 1989 31 open has the original 454's with 1200 hours.
The still run well but I am a realist and I know at some point in the not too distant future I will be thinking replacement.
Any ideas on direct replacement and suppliers would be appreciated.
Do I retain the gears, etc are questions I'd like to know.
Not a fan of the newer model full electronic motors due to support issues in BDA.

Assuming you are fresh water cooled 1200 hours isn't a terribly high number of hours depending on how the boat has been run. Not unusual to see 2500-3000 hours on the lower end especially pushing around a relatively light boat. The top end is a different matter and may be due soon but that's a lot easier and cheaper than a repower
Mercruiser 6.2 is a direct replacement engine with similar HP and torque ratings. Transmission is compatible and most likely no need to change props. Guessing $12+K per engine plus installation.
Alternative is to go with a reman long block which will probably be around $2500 each plus install and labor to swap out accessories and manifolds.

I have an 86 36' Open with 454's. About 4100 hours on them. Had a valve job somewhere around 3000 hours. Just keep the impellers changed and motors cool. Change all fluids as recommended and tune up as required. They should last you a long time.
