"I have a 89 model johnson 70h

"I have a 89 model johnson 70hp that starts up fine, then after sitting for bout an hr of fishing wont start. Turns over but dont fire. Finally it will start (after multiple tries and letting it set for little while) and continue to start the rest of the day. Happens each trip. Also a buzzer is going off periodically while running. Any ideas?"
 
"I would have taken apart all

"I would have taken apart all contacts and connections, cleaned and used contact grease. Particularly ground connections needs attention. Clean out threads from corrosion.
The buzzer might be anything from a defective buzzer to a real alarm. If constant -probably temp. Might be time to change impeller and thermostat, and relocate the pee-hose to the top of the cylinder block if You still have the one that is going from the exhaust cover."
