Gordon, I just picked up a used W-21 to re-power our 28' Irwin. I was
wondering if there was a Westerbeke group some where. When I pulled the
head (needs a valve job) the valves had what looked like a Mitsubishi
symbol on them. I suspect that it's a Mitsubishi based block and I was
wondering if it was based on one of their tractor diesels like a K3a.
Thanks, Jim
