Took the boat out on Saturday up the Cooper. Ran great all day long with no issues. Flushed the motor on the fresh side of Bushy and pulled the fuel line and let it run dry. Got back to the house and was cleaning it up (30 minutes +/- out of the water) and I smelled something burning. Looked back to see smoke coming from the cowling. Pulled the hot wire off of the battery, just in case it was an electrical short, and pulled the cowling off the motor. Could see smoke (white) coming from the bottom edge of the flywheel. Checked further and had fried a coil which is on the side of the motor. What could have caused this? I have yet to pull the flywheel to see what had burned. To my knowledge, the only thing under the flywheel is a voltage regulator that feed spark to the two coils. Am I right on this? I’m kinda stumped. I need to fix it, but even more impotant, figure out what caused it. Thanks.

Has to be something hot wired. Your fuse should have blown. The only way you cause electrical fires is power going to ground. It should have been protected. You have a stator and a pulser coil under the flywheel. Voltage regualators are usally on the side, or somewhere else, unless it’s older Johnson engine.
Do you have any aftermarket adds like an additional sensor that is not factory that they may have strait wired it?

The stator will supply the power to the coils, the pulser tells it when to fire.

Dang Tex, sorry to hear you’re still having troubles.
Thanks SH. Me too. I think that the mechanic may have caused this issue. We were discussing moving the key start to the rear of the boat and he was showing me how to wire it up. He used a screwdriver to cross the leads and “bumped” the starter. After the spark, the motor lost electrical power @ the ground. So instead of repairing it he made a new ground and attached it to the side of the block, bypassing the fuse (which probably blew when he hotwired the motor). Thanks for the info SCboatworks. I sent you a PM SC.
