The motor is a 2000 Yamaha 90. It runs fine and everything but for some reason the water that comes out is always cold. I am worried that the circulation pipes or tube or whatever in it is plugged so the water just goes Straight out the nozzle. (or whatever it's called) Does anyone know what is going on here? Also, a mechanic put a thermometer in it and the warning beep goes off every now and then. So I will just stop for about 30 seconds and the beeping stops. I go off on my way and it won't go on agian. I don't know if it just has a mind of its own or the motor is actually overheating. So basically I think that the water isn't getting through the right parts of the motor and that makes it overheat. (If it really is overheating)
