I have a Robalo with twin 115 Johnson's. I am having a problem with the starter motor on the port side. I've changed sylnoid and tried a different starter with the same results. When I turn the key over the starter just spins and will not engage the flywheel. If I connect directly to a battery with jumper cables, it pushes out the starter gear and engages the flywheel and turns the motor over. It seems to be a grounding problem. Any suggestions are welcome.<br /><br />thanks
