Dave, if you run around 100 hours every season then change your oil at the end of every season. If your boat is going to sit for a few months you should not do that with oil that has very many hours on it. You could change at 50 hours and the end of the seasopn, but I don't.
Isaac, you can leave the plug wires for two plug changes without much problem, usually.
