Westerbeke turning over hard

I just bought a 72 Pearson 35 with a Westerbeke (86) 30. The boat had been badly neglected and sat at dock unstarted for a year. When I had the broker start it, it turned over very fast and started within a few turns. It ran beautifully and was exceptionally quiet. Unfortunately all of the engine peripherals looked bad including the injector system. I hired one of the best guys in town to replace or rebuild everything so I would'nt have problems at sea. He did exactly that along with a new fuel system with two filters, etc. He started the engine, ran it about eight minutes and shut down. He made a few adjustments and restarted it. This time it seemed logy but started, ran about 15 seconds and shut down. He went to restart and it was turning over hard and has not been able to be started since. He even pulled all the glow plugs and it still turns over hard! Any ideas?

Re: Westerbeke turning over hard

If it was turning over hard with no compression and the starter was getting adequate juice I'm going to speculate that it's something internal to the block. Perhaps sitting unused for a long time there was internal corrosion that took 8 minutes to come loose. Maybe the rings. Did you get an oil analysis done?

Re: Westerbeke turning over hard

There's nothing wrong inside that engine - its something simple in the cabling to the starter or the solenoid. Don't look for complicated problems folks - its usually the simple stuff that gets you.

All of the more obvious stuff has been checked, and the starter had not turned over enough to overheat it.


The starter will be removed again to make sure nothing slid inside when it was out last time.

Not yet, the engine is still in being serviced by a mechanic. He says that he has never been beaten by an engine and this wont beat him either

We are at this time getting ideas that may help us solve this. What your saying here sounds feasable.

Re: Westerbeke turning over hard

I have a W58. I had a somewhat similar problem. The engine ran, but the max RPMs kep getting lower and lower until it wouldn't start. It turned out that the water injection elbow at the end of the exhaust pipe was a water jacketed type and the space between the inner wall and the outer wall had become clogged with 30 years of rust, etc. This was the space for the exhaust gas. The back pressure was building and eventually the engine wouldn't start.

I replaced the exhaust pipe, which had rusted out, and the elbow and it's fine now.

Re: Westerbeke turning over hard

Back when I had a diesel engine it all of a sudden became a hard starter and then would not start. Turned out the head gasket sprang a leak. Not sure if it's the same issue with your engine but, mine was a Westerbeke 27. Compression test by mechanic should be able to find out.

Re: Westerbeke turning over hard

I was taught 60 yrs ago in high school auto shop, When in doubt,clean all batt conections, and test the draw after that ! Most slow turn overs Ive seen in cars boats heavey equipment ect have been caused by either bad connections, or bad batts ! Just my 2 cents
