I have a mercruiser 3.0 alpha one I recently bought for a project. When I bought the boat the previous owner did not have the key so i replaced the ignition switch thinking I could test the motor and installed a new battery. The ignition was installed properly and the battery is fully charged, but when i turn the key the motor does nothing, no clicks or anything. The Gauges will move if I turn the key all the way to the Right which I am assuming is the run position but as soon as I let go of the key the gauges do go back to the off position. Because I hear no clicks I’m thinking the starter and the 50 circuit breaker which is popped may have something to do with it. Has anyone had any problems similar to this?
