I have a 1996 Chaparral 1830 with a 4.3L mercruiser motor, carbuerated. While out on the lake wakeboarding or tubing I will sometimes shut off the engine to let people on & off, jump in the water, etc... Sometimes the boat will not restart. I turn the key and the starter warning signal is much lower than normal. When I turn the key to start I get nothing. If I let the boat sit for 5-10 minutes it seems to reset. Also, I have disconnected the battery cables, then re-attached. This seems to reset it as well. Looking for help to track down the problem.
