    1980 120hp

    Get everything from a newer boat. Everything between the prop in the back forward to the pulley on front or the motor.... Including wiring, controls, etc

    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

    If your boat has a 4.3 in it, it was transplanted. The 4.3 came out in 1985

    1980 120hp

    I personally would get a 1992 or later prop to pully setup to get the newest drive and motor combination.

    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

    Help! Overheating 3.0, not impeller or circulation pump

    Overheat is lack of water flow. Either no flow in....or no flow out Is there flow from the raw water pump thru the hose to the thermostat housing?

    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...

    Conversion advice

    You can use the block and heads. You need a whole bunch of marine bits to make it work. You are no further ahead than your 1984 block and heads

    Conversion advice

    There have been about a hundred outboard conversions started on iBoats. About a dozen completed, about 1 or 2 that came out well. The transom must be reinforced to use a pod As for your existing motor, other than the short block, there is nothing that could be used if you convert to an SEI...
