I have a yamaha 35/50 out board. It runs great at idle. As soon as I go to full throttle to get on step I can run for about 1-2 minutes and then I get an alarm. Im thinking it may need a new water pump and thermostat but Ive never changed a water pump on a boat motor.
Is this something I could do my self?
Do I have another problem possibly?
The shop is about 2 weeks out and I wanted to use my boat next week. Don't really want to pay 500 dollars or so to have it sitting for weeks.
