I have a mariner 150 magnum 11. The audible goes off all the time as soon as i turn the key on, my temp guage no longer works i get a louder audible when i ground the temp sender and my temp guage pegs hot. It runs great for 5 min. then shuts off, i wait a few then it starts then dies , when it runs i can turn the key a little and the audible goes off and my fuel guage goes off , any suggestions?

May be the oil alarm if it's a oil injection model, need to make sure oil injection is working properly.

i checked the oil injection on the tube that goes to the fuel it was empty, i took off the oil pump and turned the motor and the notch that holds the shaft was not turning does this piece come out? if its fubared can i disconnect the audible system and pre-mix the fuel and what ratio
