Started my motor on the muffs after its winter nap to burn off fogging fluid. Alarm sounded after a couple minutes so I shut it down. It was peeing fine so should I change t stats or poppet valve? If peeing poppet valve ok? Impeller or water pump, just done like 2 years ago, I usually go about 5 or any issues(like this one lol).

I was going to launch and try on lake as maybe muffs were letting to much water escape before I try anything, will be next weekend probably.
