Ok, so this is a weird one. I just bought an 89 Bayliner 2755 'as is', needless to say I have been working on it constantly. My latest problem is I cannot get any accessories working unless the engine is running OR has been running recently. What happens is this, if the boat has been sitting for about a day without running and I flip my battery selector to either battery none of the accessories work when i turn the key to ACC or RUN. If I start the boat and let it run for a bit all of the accessories, including all my gauges, spring to life and work perfectly. Then, when I turn off the engine almost everything (except the gauge back lights) stays on for a bit no matter what position the key is in. Any ideas on this one would be most appreciated, thanks!

The engine is a Mercruiser MCM 260 and a Cobra Outdrive.

Re: Boat accessories only work when engine is running

I found it. The main electrical connection for all the accessories coming from the engine to the helm was loose. I noticed it while I was working on the engine, I bumped the connector and heard the water pump kick on for a second. I love cheap easy fixes :joyous:
