    Retiring my Johnson '71 25hp

    Sad.... why not fix it somebody here must have parts and guidance for your issue. up to you ... you can buy a lot of gas and a spare fuel tank for what you will save on a good fix. how was compression ?

    start by comparing the ohms value of the good coil (boot to engine frame) if identical suspect coil is likely OK if suspect coil checks out as OPEN (infinity) start by simply twisting the plug boot , wire and coil end connection RETEST boot to engine frame If OPEN (infinity)...

    well there you go... better fix what ails it then ... Racerone.... any technical reason why premixing would not work .. be it 50/1 or 40/1 if the needed parts are truly NLA anywhere ? Is it the end fatality of the engine ?

    Trim

    see pict. in the non operating mode both blue and green are grounded with either wire waiting for the other to flip to +12V thus reversing current flow to the trim motor

    Trim

    green and blue motor works both ways so Voltage/current must be presented in alternate directions ..up or down since the motor can trim UP ok then both wires from the relays are ok and do pass juice to the motor because one wire has 12v and the other is grounded. In the...

    1999 Evinrude (90 hp) E90FPLEEC - Runs fine at idle speed. But stalls when running about 3000 rpm

    first things first... up to you... .me I would just open the VST to check the vent float and needle. VST is just a can with a water coil to cool the fuel and let vapors escape via the top needle valve. they have been know to become stuck/rusty if the incoming fuel is contaminated with...

    1979 Evinrude 35 hp Water Pump Issue

    3 inches underwater may not be enough to prime the pump properly . Remember the old farmer's hand pumps.... they needed a quart of water to start pulling water from the well. retest with the LU submerged and spin it with the drill to confirm the pump is pushing water out the pump body...

    Temperature switch circuit 2000 Johnson 150hp

    If my compression readings are indeed low at 92-94psi would this not be enough to pulse the fuel pump causing it not to pump fuel? Actually compression#s inside cylinders have nothing to do with the vacum (crankcase pressure loss during the piston up stroke) inside the crankcase. the...

    understanding idle on 1971 Johnson 50 hp

    to idle properly the idle circuit of the carb must be clean to allow proper fuel vapors to be generated by the upper part of the carb. If you feel adventurous pull the dime size plug on top (drill a small hole and use a nail to pop it out do not drill deep !! inspect /clean the small...

    1999 Evinrude (90 hp) E90FPLEEC - Runs fine at idle speed. But stalls when running about 3000 rpm

    don't assume the small lift pump is bad you also have the fuel filter asa possible source of restriction....then the VST needs to vent properly otherwise entry into the VST of new fuel will be compromised . Check vst top cover for a small float valve/needle which closes when the VST is full...

    Temperature switch circuit 2000 Johnson 150hp

    I can manually choke it, pump primer bulb until I get fuel into the manifolds and it starts fine.... anything wrong with the lift pump ?? feeding the vst no expert on these big engines but.... Carbs look like regular old style float valved carbs. Strange that no fuel reaches them .... any...

    Trim

    maybe this can help basic 2 wire ptt the relays simply forward or reverse the current to the trim relay. if motor works one way seems logical it should work the other way (wires to the motor being ok ) and the big IF is ..... are relays applying juice to the motor in the...
