I have a 285 hour 8kw diesel Westerbeke which has been completely trouble free.
This season has been unusually hot so I've had to utilize it quite a bit. It starts and runs
exactly as it did when brand new. After about an hour it looses RPM, slows down until
it shuts off completely. No over heating, no low oil pressure, no unusual noises. It starts right
up but will run at normal RPM for a short time and then slowly slows down and shuts off.
I climbed into the engine room and started it from the control panel. I watch while the engine
started to slow. The plunger Westerbeke Part 023041, Solenoid, Fuel 12Vdc I think this is the correct part
starts to move to the left away from the running position as the engine slows down. This part was replaced
maybe 5 years ago. So you would think it's a fuel filter or fuel pump, or fuel regulator issue?
The filter is clean, Racor, /the engine runs smooth until it dies. I'd like to think I need that same part, but
when running it's magnetically firmly in place. Where else should I be looking or should I hire a
professional.
Thank you,
