Over the weekend I replaced my starter on my mercrusier 7.4 changed out the Ignition Module in the Distributor boat started up and was running ... yesterday I took her out and cruised at no more than 2000 rpms for about 5 miles parked the boat and once again went to go start it and the starter would not turn the motor this is the 2nd time in 2 weeks I have had the same exact problem anyone know of an issue I might be missing? Boat ran fine now it the starter cant turn the engine over
