I have a 2003 Yamaha 200hp 2 stroke and went out to fireworks last night and all worked well. had some battery cable issues (corrosion) earlier and replaced with good connectors. Fireworks over she started right up. No waked to the Tiki Bar in Rye and tied up to the dock. when it was time to leave engine wouldn't crack. just a whir from the starter (would not pop up and engage the flywheel). Running lights, fish finder, radio, engine tilt all work fine. Is there still corrosion on a battery cable I might have missed or is it time for a new starter?
