Hey guys I took my boat out of storage last weekend and changed the oil startd in up in the driveway and everything was fine. Went out to the lake and no start. I began trial and error process and checking everything out. I am thinking it is electrical problem. A blown fuse maybe or something. It turns over and acts like it wants to fire but it wont start. If i hold the key all the way to start it fires up but I let go because the starter is still turning. I have an 91 omc cobra 4.3L. Any help would be much appreciated!
