What engine is in your cheoy lee?
 

I've got a clipper 42' and I'm not sure what was originally in these boats. I've currently got an older Isuzu C-240 (actually a "QD" - some outdated nomenclature for the same engine) which seems to have been hand retro-fitted to bolt up to a 2:1 Velvet Drive.

But my maintenance log clearly says this was not the first engine in the boat.

The maintenance log was started by the third owner, and I have no idea what was originally in it. I'm kind of curious :-) Supposedly the motor was totally blown and was yanked out in 1981. I sort of wonder how someone blows a diesel engine in 10 years, but I guess it's not that surprising. Of course the engine that replaced it is easily as old as the boat and still running strong.

But what came in your Cheoy Lee?

My CL Luders 36 has a Westerbeke four 107. With 107 cubic inches it can produce up to 40 HP @ 3,000 RPM and would burn 1.3 gph. A more useful setting is 2,000 - 2,250 rpm making a bit under 20 HP and using about .7 gph.

I think the transmission ratio is 1:91 to 1 but am not certain. The propulsion system ends on a three blade prop, the pitch of which is presently unknown.
