The venerable old 1959 Volvo on my 19' Lund finally died (in a kind of cool way - a story for another post though) and I'm replacing it with an ob in the 115-150hp range.
I found a donor boat on Craigslist and checked it out today. Wanted some opinions (first Merc and first 'big' motor)
The motor is an 82 150hp v6 currently on 1979 fiberglass Invader. It's a clean motor cosmetically.
Compression readings: RH from top to bottom: 120, 115, 90; LH from top to bottom: 90, 90, 120. Is this a rings issue or should I be wary of cylinder wear?
The other issue was a failure to fire. Cranked well and the starter seemed strong. Spark plugs (gapless style) all had strong spark. Fuel was not getting to the cylinders so I would assume that the problems is clogged carbs (owner was unsure if it had been run dry last time it ran so probably wasn't).
So I wasn't able to hear the motor run. I told him to give me a call when he got the carbs cleaned out; so my question is should I still be interested with the compression readings the way they are?
Definitely not buying before hearing it run though
