Westerbeke
12.5kw Genset
I have a 12KW Westerbeke four cylinder engine. I had gone through the whole engine and put a new back end on ~5 years ago. Since then standard maintenance, filters oil and such, the generator has been flawless, always started within 2-3 secs on cranking over. About a month ago it started up very strangely, it started like it always does but did not ramp up in rpm and stayed at some much lower rpm and died, like no fuel. So I started it again and then shut it off right away, re-started and ran great like nothing ever happened. It has ran this way every weekend since and will run for hours/days with no problems. But continues to need to be started twice.
I checked the lift pump, primes just fine and keeps running on/off as needed to keep pressure up, filters are clean (just changed). Checked the run solenoid snaps into place correctly and stays there, moves free and easy no binding of any kind. No smoke or exhaust residue to speak of in water.
I am completely stumped over this. Any ideas would be greatly appreciated.
