No!!!!! You must use a marine alternator.Fuel vapors are heavier than air and collect in your bilge. Marine alternators are sealed to prevent sparks that can cause an explosion.same goes for starters, fuel pumps, bilge pumps etc.<br /><br /> Jim
You can try to have it rebuilt. Typically the brushes wear out and and alternator shop could replace them for a fraction of the cost of a new unit. Also since they are repairing the original unit, the sealed characteristic should remain intact.
