Re: [Amel] Yanmar Shutdown

Thank you Lars and Eric for your input. I did change the solenoid some
time ago. There was a temporary improvement but not a complete solution.
I will take the stop button apart when I can find time and see if that

I have just solved a similar problem on my Santorin. It turned out that it
was a combination of a faulty STOP-button and a not quite trustworthy
solenoid on the motor. By replacing the solenoid and taking the
apart and cleaning it everything worked fine again.

Subject: [Amel] Yanmar Shutdown

Since new shutting down my Yanmar 100 HP engine on my Super Maramu 2000
(414) has been erratic. When the red stop button is pushed it can take
up to 20 seconds for the engine to stop. Very irritating and potentially

I contacted Amel when under warranty and they sent me an additional
capacitor to fit in the solenoid circuit. Frankly it made no difference.
The solenoid mounted on the engine side near the alternator operates
whenever the button is pushed and held in, and I have inspected the
connector to the fuel shut of valve. It maybe a faulty or sticking shut
off valve but I am reluctant to remove it till I have heard from other
owners who might have had the same problem.

Any clues please?
