Quick question: Today we took our boat on the water, everything ran fine, until we suddenly were trying to move to a different fishing spot. As I went to start the engine, it wouldn't crank over, it was sort of a humming sound, I took the cowling off, and the starter pinion was not going up to engage the flywheel. I then tapped around the pinion gear lightly with the handle of a screwdriver, tried it again, then it engaged the flywheel, and started right up. It did this a couple of times today. Does anyone know if this could be a starter problem or just a pinion gear needs some lubricating, etc?? Your help is appreciated. Thanks.
