Pretty much every marine engine has a connector or two in the engine/panel wiring harness. They are there to make installation convenient at the factory, but, after a few years, can cause a lot of problems as corrosion and wear set in. I’ve seen electrical problems on every size of boat regardless of make or engine type that bypassing these connectors has frequently cured. I suggest cutting out the connectors and splicing the individual wires together using top quality heat shrink crimp butt connectors. In the event that the engine has to be serviced, removed, or replaced, the wires can be severed and rejoined as needed.
I’m not sure that this is the root of your problems but it’s a good place to start. Rich Knowles Nanaimo, BC Boatless.

Could also be your starter solenoid. Good luck. All the best, Edd ------------------------------- Edd M.

Normally, when the main switch is turned to on, the oil pressure alarm sounds. Pressing the starter button starts the engine and the alarm stops. This season, after a few successful starts, when I turned the main switch on one day there was no alarm and nothing happened when I pressed the starter. No cranking. Not a sound. My batteries spent the winter in my basement and were fully charged. As well, shore power was plugged in and the charger showed full charge on both batteries. This happened once or twice last season but when I repeated the process the engine started. I assumed that the main switch was worn out and ordered a replacement Yanmar switch from Rosborough Boats. It was my first dealing with them and I was very impressed. Rob Manual had a new switch to me within a day. I had carefully labelled and photographed the connections at the old switch before removing it, but when I installed the new one it didn’t solve my problem. When I keyed the switch on, I got a very weak sounding alarm and pressing the starter button got no reaction. I’m unskilled at tracing problems, so thought I’d ask for help.
