    A Serial # for the Motor would make it easier to find which Carb Kit is required The Rebuild Kit you purchased, was it a Genuine Mercury/Quicksilver Kit, or a 3rd Party Kit? Also when you reinstalled the Carb, did you verify the Sync between the Carb, and the Ignition Advance? What condition...

    Johnson 5.5 CD-20C carb and running issues

    Welcome to iboats That would be a 1963 Motor, and will require a 24:1 Gas:Oil Mix. You say unburnt Fuel is coming out the Exhaust? If you have a ruptured Fuel Pump Diaphragm, Fuel can build up in the Crankcase, and be expelled by the Crankcase Vent/Drain into the Exhaust Housing. Does the...

    My new project.1972 johnson 25e72r .

    I believe 1968 was the last year they used Packing and a Packing Nut to secure/seal the Idle Mixture Screw. In 1969, a Plastic Retainer, and what they referred to as a Bearing replaced the Packing and Packing Nut

    Hesitation at wot help

    So this is a New to You Motor? A bog/hesitation when the Throttle is advanced can be due to many Issues, often a lean Fuel Condition. Did the Previous Owner give you any Maintenance/Repair History? How long did the Motor sit since it last ran? Was the Fuel System drained, or a Fuel Stabilizer...

    Etec 75 hp

    Stay with the 88. Simple easy to work on Engine, that isn't dependent on Impossible to Troubleshoot Electronics, on a Engine that is an Orphan. I guess both are Orphans, but Parts will be available for the 88 for far longer...
