Re: Thinking of Losing My Inboard
The rebuild was from the local Yanmar dealer. It was a YSM 12, an older 1 cylinder. Parts are available, but expensive. I've done gas engines, including DOHC Alfa engines, so I figured a 1 Cyl couldn't be that bad. After pricing parts, the labor wasn't bad, and it would be done in two weeks, rather than numerous weekends. Even around here winters aren't that long. As mentioned, the Atomic 4 is a good option, as long as reconfiguring doesn't expand the job too much. Several marine engines use Kubota as a base, so parts shouldn't be a problem. My boat was lost in Sandy, and I found a duplicate with a "recently" rebuilt YSM 12, so I ended up finessing that issue.
UOTE=Kielanders;1110625]$5300 seems steep. Did you have the rebuild done at a marine shop?
I've done a few automotive engines (gas). I was going to have the Yanmar (head, block, crank, & piston) professionally remachined (w/ new valves seated), doing the breakdown and reassembly myself from a full rebuild kit - replacing other components (impellers, oil pump, etc) as necessary. I haven't reviewed the manual yet to write-up a game plan.
Something I'm missing, is this harder then it seems on a marine engine?
By the way, does anyone know the Kubota equivalent of a Yanmar 1GM10 for parts sourcing?[/QUOTE]
