So heres the question hopefully someone can help me out ! I’ve got a yamaha 130hp and evertime we run it either full throttle or almost full throttle the alarm comes on. Turn it off for about 10 min.s and its fine. Runs fine as long as its not wide open or close to it, any ideas? Any help greatly appreciated thanks !! Oh its a 1999 .
replace your waterpump and check the impellar housing to make sure the plastic has no blockage
Water pump was just replaced the pee hole is strong. Could it still be the impellar housing?
did you replace your thermostats?
it’s tough being a gamecock fan!
could also be an obstruction in the water passages in the head
