I have a 23 HP Volvo
MD-11 in my Cheoy Lee
35. Raw water
cooled. It starts and runs okay but has very little cooling water
through-flow, say 1/2 gallon/minute. Thus it tends to run hot although it never gets into the red on the gauge. (I also tend to avoid long runs and minimize use of the engine
because of this issue.) I have changed the water
pump impeller and checked for clogging in the transmission
and other accessible passages, but have found no problems. This leads me to conclude that the internal engine cooling
passages are crusted up from salt
accumulation. I have read that this is a common problem on the MD-11.
1) Other takes on my diagnosis? What other checks should I run t rule
out other possibilities?
2) Can anyone recommend a SF Bay
Area diesel mechanic
who doesn't charge an arm and a leg to assist with diagnosis and remedy? Preferrably East Bay--Richmond-Berkeley Area.
3) I could also use some additional HP and the thought of re-powering has crossed my mind. Does anyone have budgetary numbers for re-powering to say 30 HP with a new Yanmar
