I just came in with my boat and had a problem. When I opened it up 3/4 to full speed after a short time it would quit and die in the water. Sometimes I had to remove the cover and cross the solenoid with a screw driver because the key wouldn't start it . Other times it would start right back up with the key .I had all other electical items working , horn etc. I tried it about 5 times before I thought it best to come back in. At lower speeds it runs okay. any help? fuel pump? Starter switch? all of the above ? I have owned the boat about 7 months so I don't know when it was tuned last. Thanks
