You have to decide whether the rest of the boat is worth the money
and effort of replacing the motor
I bought an old boat with a bad motor
, but I thought it was a good buy as the boat had good canvas
, new running rigging
The old Volvo
(MD7) had bad internal corrosion
were no longer available. I was able to find a used Yanmar, with good compression
, on craigslist for $1500. It's worth paying a mechanic
to inspect. Two years later it's still running well.
I would have rebuilt the motor if the parts
were available, though.
Note: A different brand motor will need to be adapted to fit. Volvo
props spins in the opposite direction to Yanmar, so I had to replace the prop. The motor is a different length, so I also changed the shaft and motor mount. (again used parts) Sounds like a lot, but doable once you get your head
around the process.
I made up a jig with the old motor and then made the new motor fit the jig at the same angle / distance. The only build out was to extend the motor mount bracket. I used the opportunity, while the motor was out, to replace the cutlass bearing and stuffing box as well as repaint the engine bay. Man that was rewarding. All good and clean and fresh.
