    so why not post up what all 3 cylinder compression readings are now. there is a good possibility, that washed out cylinder was harmed from the extra fuel if this was not a premix. you are throwing bits of info out there and then come back and say that was not really true. not much can be...

    Yamaha, 4-stroke Mid Range Power loss

    timing light will tell if timing is in spec and advancing as it should and it will show if spark is good when problem shows up. could be off idle ports are dirty, so has a hard time transitioning to upper RPM. heated sonic bath cleaner may be a good idea

    1998 Yamaha 9.9ELRX won't rev up past idle?

    Thermostat housing hole.

    my rig is high enough while on trailer that I leave the motor down while trailering and have not hit anything yet.

    1981 Suzuki DT9.9 water pump issue

    antifreeze does not boil at the same temp of plain water, so over the boiling point of water is not good. your motor is getting too hot it has cool water being pumped into it , or at least it should have plenty of cool water pumped in to keep it cool

    96 Yamaha 115 getting overheat alarm

    thermostat controls water flow thru the motor just like on automobiles, it sits in a water cooling passage, so you should be able to see what it looks like when you pull the stat out. the other cooling passages will require heads and other plates to be removed to inspect and clean if the stat...
