I was reading through discussions on problems associated with starting Yanmars. There was a lot of modification being done to the solenoid wiring in that it appears in a lot of cases to be undersized. The one thing I did not find was a descriptive on how the problem manifests itself, was the solenoid weak, did not engage? I am experiencing a new problem where the boat was in the yard for two months and upon splashing would not start (turn over). In troubleshooting I found a loose connector and voila it cranked right over, later I tried just before leaving and dead again. I ran a wire pair from the momentary start button down and I could hear the solenoid clicking so I assumed I have a dead spot on the commutator, but an quite curious about the aforementioned issue. The started had no problem prior. Getting to the starter is a bear, growl! I will be installing the hatch port access through the bathtub to get access to the engine port side pronto.
