    Getting hot at WOT.

    Anything over 180 is an overheat Running hot is lack of water flow. Bravoitis limits water flow. Remember, your exhaust is a bunch of rubber hoses that melt around 250. As your water flow diminishes, the exhaust temps go from 200ish to 1100idh

    No power to pin 86 when ignition turned on.

    What specific model number? If this is EFI, the ECM controls the relay

    What's this? Off my 1980 20' wellcraft with mercruiser 4.3 engine

    Help! Overheating 3.0, not impeller or circulation pump

    Yes. Should fill a 5 gallon bucket in 15-19 seconds with motor at 1000 RPM. Should shoot a good 8"+ up when holding the hose vertical However before proceeding since you stated you have water flowing from the raw water pump. Pull the thermostat housing apart and clean the blockage

    Help! Overheating 3.0, not impeller or circulation pump

    Pull the thermostat assembly and remove what ever is blocking it. If you have water coming from the raw water pump to the thermostat housing, you should have water to the exhaust as that is a straight shot unless there is a blockage or there is no flow from the raw water pump Running your...

    1980 120hp

    The timing gears for the 120 hp 2.5 liter have been available since 1962. Same parts as the 153 in the Nova ii, same parts as all the 196/230/250 inline 6 Agree to swapping to the 3.0

    Conversion advice

    Your vintage is a mechanical shift (1981-1984), not the earlier hydro-mechanical shift (1978-1980) If you want to look at the stringer, look at the following problem areas: Raw water housing leaks 3-piece vertical drive shaft splines Ball gears Tilt motor and hammer coupling The only source...
