Happy sailing season, all!
I have a strange but repeatable engine starting behavior that has me concerned (E-35, 1984, M25). First noticed this behavior mid-last season: when I would hit the start button I would get a very brief crank from the starter motor and an abrupt starter motor stop (this brief starter motor crank is very short, like < 1/4 second or less). After this abrupt starter motor stop, I release the start button, repress the start button and the everything will crank normal and start the engine just fine. My batteries were at end of life last season and I suspected failing batteries ... just changed them out for new a few weekends ago and have the same starting behavior.
This happens both first fresh start of the day and after hours of sailing and subsequent restarting returning to the marina. If, after a fresh start, I shut down the engine and then reseat right away, it will turn over normally without the abrupt pause.
Any thoughts on what could be causing this or other checks I can perform to find root cause? Do you think I have a problem (slowly failing starter motor)?
