My son and I worked till midnight last night to get everything ready for today. We put the motor back on the boat and hooked up the running lights and all of the cables for the controls.I have a 87--50 hp force and replaced the impeller. I had a garbage can full of water to check the pump and it worked fine but this morning my wife went to get the sunday paper and told me that the boat motor was smoking.I removed the cover and found the top coil smoking and cracked open on both ends. I disconnected the battery.I found that the ignition switch was left on over night.If it is like a car years ago I know you can't leave the ignition on that it will burn out the points.My questions are is this what caused the coil to burst and what else is likely to have fried.I have ordered new points and the dealer did not know the correct setting on the gap.If anyone can help it will be greatly appreciated.<br />Thanks<br />Ron
