I am having trouble starting my 1999 supra launch with a 350 Indamar in it. The batteries are charged, and the starter is getting power, (just installed a new starter). When you turn the key you can hear the solinoid push out the gear, but doesn't spin. The radio works, not sure what else could be wrong. The starter has 3 wires connected to it. I'm not sure if there could be any issues before the starter, because I'm not much of a mechanic. I will take a pic of the starter and see if that helps. (The boat is in neutral).
