Hi, Any advice
on diagnosing the situation would be great.
The boat / propulsion:
44" with two Yanmar
3JH4E engines and SD50 saildrive
Maxprop whisper propellers
What happens and when:
When I start sailing and after stopping the engine
(gear in neutral) I can hear the sound of the saildrive
turning. So I reverse... the turning noise
stops... and I replace the gear
When sailing above 7.5 to 8 knots, it sometimes happen that the engine
and the saildrive jump up and down a few times with very loud clanking noise
The noise make me think that it might be the engine being forced to turn (in reverse?). But the saildrive gear
is in neutral, so even if the propeller
unfolds and turns, it should only turn freely!!!
It does not happen often, but I need to do something as this cannot be good for the engine, the saildrive and the silent blocks.
Anyone has experienced such problem? Any idea to diagnose further and / or fix the problem?
Thank you for any suggestion.
