    Thanks Joe. It runs great and never any probs. Then, the last time out, abruptly quit running after approx. 30 minutes. 3hrs later started with no prob. Haven't been able to try some of the fixes suggested here...very pleasant surprise at all the response.

    Thanks. This will be the fastest thing to do. I have received a lot of responses on this and appreciate them...one of them is bound to work. If it isn't charging, I can probably run it in the slip for a half-hour or so and see if it dies.

    Need ideas on problem with 5.7L Mercruiser shutting down

    I have a 1996 270 Sundancer with a 5.7L Mercruiser. It was running perfect for a half hour at 500rpm off max and shut down with no warning and would not turn over.
