    Default Alternator went bad have some ?'s

    My alternator went bad. My jet is a 73 wreidt with a 455 olds. The alternator was a marine delco. Ive got an automotive alternator laying around from a 455. Would this be ok or is the spark something to worry about? My motor compartment has a lid on it so its not open. If it is something to worry about does anyone have a marine alternator they want to part with? Thanks, Tate

    Check around and see if anyone around you can rebuilt it. Mine was shot, really really bad, the internals crumbled when they took it apart, and it was still only about 50 bucks to have it rebuilt.

    I'd vote for the real deal marine alternator with that closed engine compartment. I run an automotive type and have for years, but my compartment is open.

    I'd also second the motion to try to get it repaired. It would probably be considerably cheaper than buying new. Actually they're not that difficult to rebuild and you could do it yourself if you're feeling adventurous. Brushes, diode trio, voltage regulator (if internal), and a new bearing. That's pretty much it.

    Thanks for the advice. I called a place by me they said prob $60.00 to rebuild. Being a closed engine kind of makes me nervous about using an automotive one.

    Knock on wood, mine has lasted 15 years...... it was reman'ed by a local builder. One thing to prolong the alt, is to run the larger racing pulley, slows it down considerably, as the jetboats run 3k and up in RRRRR's

    i would NOT run one of those moroso large pulleys i ran one for about a week and i would always have a dead battery by the end of the day i like to just float down river and i would start the engine for short periods of time for corse corection but still i have a brand new g29 battery in it and it would not start the boat by then end of most days just my .02

    x2 on the closed engine compartment thing, my dads boat cuaght on fire once because of a non marine starter in a closed compartment deal.
    Boating is nothing like cocaine, boating is much more addictive and results in bigger parties!

    Dont know where you are, but there is a shot in Riverside that rebuilds starters and Alts.

    Stay with the marine one.
