Due to drought in Texas last year, boat stayed in garage. Water up this year charged up batteries put unit in tank, started right up did everything it was suppose to. Took to lake, started up, ran up to fishing hole shut down. Fished and trolled for about 3 hours. Went to start motor to head in, would not start, acted like battery was low on charge. Bumped ignition a couple of times and it caught and started. put boat back in garage bought new battery, no start, bought new starter seeing how the starter is original, and a new solenoid, New starter spins but won't engage flywheel. Not the brightest tack in the box when it comes to mechanics. any help appreciated.
