"Hi I'm new to this forum. I'm not a professional mechanic, however I've done nearly all my own mechanical work for over 49 years (starting with a gokart when I was 12), mostly on cars but also some boats (inboards, outboards, and I/Os), motorcycles, lawn mowers you name it and I may have fixed it.
We took the boat out this past weekend, a 1974 Egg Harbor sportfisherman with twin 454 Crusader engines. A short ways into the trip a low oil pressure warning buzzer/light went on, however the oil pressure gauge at the helm was reading 40psi so we continued, shortly after that the engine shut down and wouldn't restart (the starter wouldn't crank). I crawled down next to the engine and jumped the starter at the solinoid and the starter cranked just fine, in addition after the intial restart from the solinoid we were once again able to crank the starter from the helm. Inspection of the oil pressure sender found 3 oil pressure senders. I disconected two so that only the sender that transmitted info to the oil pressure gauge still worked. We had no more problems after that. Am I correct in assuming that one of the sensors I disconnected was designed to shut the engine down and disable the starter if the buzzer/light was ignored for too long a period of time? BTW two of the sensors had a single wire and one had two wires going to it.
Thanks for any insight you can give me about this issue.
