new day new problem.. yesterday I replaced the 90 amp fuse on the starter, problem solved. Today I turn the key and the shut off switch to the on positions, the gauges all turn on but the engine doesn’t crank. I can jump the boat from the solenoid and it starts right up, but next time I go to start it I need to jump the solenoid again. When I shut off the key the engine stops. I replaced the solenoid maybe a month ago, which is weird that it would already be bad. Any ideas?
