My sailboat has a Westerbeke
42B4 diesel engine
It starts normally, and can run for hours at cruising speed. Later, when I need to wait for as bridge opening, I would witch between neutral and idle speed for some time. Then, when bridge opens, I would press ahead, but the RPMs wild slowly drop and engine
stops. Even at full throttle. Sometimes RPM
would fluctuate without giving full power.
Restarting the engine sometime fixes the problem temporarily, until the next bridge...
- In neutral, the RPMs are holding fine, the problem is when engine is engaged.
filters are freshly replaced and clean
- Tightened all fuel
line clamps, etc. - fuel and air leaks
- Prop is clean
Any suggestions will be greatly appreciated.
