Rich -- when I had a top-end rebuild a few years back, the diesel mechanic I used (a legend in the northern Wisconsin area) said the QM series was originally designed for industrial uses like pumps and compressors, and given the sparse use on a sailboat by comparison, it should last just about forever. So while they're large, heavy and noisy, they're also built for heavy use. He suggested that, with proper maintenance, mine should be good for another thirty years before it needs more work.
So you should be good for a while... :^) Fred Street -- Minneapolis S/V Oceanis (1979 C&C Landfall 38) -- on the hard in Bayfield, WI :^( On Sep 19, 2012, at 7:23 AM, Rich Knowles wrote: > I got my Yanmar 3QM engine back from the rebuilders and into the boat > yesterday.
