If the Volvo engine is still in production, I would rebuild
. If the block is out of production, replace.
My boat had a Westerbeke
that hadn't been in production since 1987. Parts were available, but the prices were beyond ridiculous. I ended up buying
Phasor (same as a Beta Marine
BZ482). The Kubota Z482 it's based on has been in production for years and is still in production, so parts are available and cheap
My costs were:
complete salvage motor
and control panel
rebuild kit $130 (which I ended up not using because the trans worked fine once it got a thorough cleaning)
Machine shop costs for heat exchanger
repair after I broke a header stud off in it while disassembling the engine $400
Replacement Kubota Z482 bobtail & freight $1950.
Two cans of Kubota blue paint
(which is actually green if you ask me) $20
Remanufactured starter from ebay $92
from ebay $84
Air cleaner as the salvage motor didn't have one $40
Total cost for brand new marinized engine $3216.
That's still less than the parts costs quoted for the rebuild of my Westerbeke
. It's also significantly less than the $6500 or so quoted for a new Westerbeke or Beta Marine
Alignment took a long time, but the hardest part of installation
was lifting the motors in and out of the cabin
If you don't mind doing the work and you're in no rush, check your salvage yard, watch the ads on ebay and craigslist, and see what you can find. But again, it's only a good deal if the motor is still in production.
