Re: Diesel or noises
Our 3gm30f Yanmar/Kansaki combo does that too.
As soon as the prop starts to turn at about 4 knots it makes a noise.
It sounds like a heavy piece of metal running over a cam and hitting the prop shaft. It's rather annoying but it doesn't do it all the time.
I talked to the local Yanmar dealer and they said it is was a common thing??? and if you don't like it you could put a shaft brake on it.
I had forgotten about it as it hasn't done it in quite some time.
We have three rules;
No bleeding on the sails.
No slobbering on the charts.
