So last summer the last time I took out my 19' Viking Sport Deck with a Mercruiser 470. I had problems getting it started so I charged the battery over night and it started up right away. and drove it around for a good hour with the engine on with no problems then I stopped and we all got out and swam. well when I tried to start it again it was dead again I had to get towed in. is this a problem with the battery or the Strator and regulator?

also how do I test for both? would I be able to take it into an autozone for these test or would i have to take it to a marine mechanic?

Please let me know how I should handle this

Thank you

J,
It sounds like the stator or voltage regulator has gone bad if it hasn't it will sooner or later on a 470. Charge your battery back up and start her up, using a volt meter connect the positive side of the volt meter to stud on your starter that has the orange wire coming from your voltage regulator. It should test to around 14 volts if it is good. If it is less than that you have a bad stator or voltage regulator. It doesn't matter which is bad, neither is worth fixing. Get an alternator conversion kit and install. I got mine from Breezeworks one of the most reasonable priced on the market.

Hope this helps,
Larry

Thanks Larry,
I will check it out. also i found one on ebay for $10 cheaper and puts out 50 more Amps

I have a pretty big sound system so i think this one will work a little better.

Same thing happened to me last summer. I got the ebay kit, and it works great so far. The guy was also great about getting back to me quickly with a few questions I had about the install.
