I have a 1989 Johnsoon 150 V6. Sorry I don't know the technical terms for all these parts. When I turn the key, the gear that the starter kicks up to engage the flywheel doesn't kick up high enough to engage the flywheel.<br />The battery has a full charge, and it doesn't do it all the time, probably 65% of the time. Also, sometimes when it engages, it only engages for a short time, not long enough to start.<br />It will usually eventually start, but I'm selling the boat and can't sell it this way.<br />I'm assuming this is the starter. Am I correct? Or could it be the solenoid, or even the battery? I did fully charge the battery.<br />Tell me where to start and how to test the starter.<br />Thanks much.
