    OMC control unit high idle failure

    I have an 82' 50hp Johnson with the stock OMC control unit. My high idle lever has never worked, the lever, when pulled up, does not seem to grab anything and has no effect on the starting capabilities. It appears the cam that engages the throttle lever is bent and unusable. When I first...

    Installing temperature sender

    I have a 1982 50hp Johnson and I'm looking to install a temp sender. I want better feedback than just the current overheat horn (which I'm not sure works) but my problem with installing a temp sender into the coolant stream would be that it would not be consistent, as the water temperature would...

    Fuel pump addition

    Hey guys, I have an 82 50hp Johnson that I've had a fuel pump hooked up to for priming purposes. It is not a flow-through pump and has been causing me issues while running (I have to routinely tap the prime button to keep it running). I realize I could just use a primer bulb, however I'm...

    Strange humming noise

    I have a 1982 johnson 50hp motor that runs pretty well. However, usually on a cold start, the motor will turn over, and instead of take off running, it will start to hum until I turn the key back to off. It may do this several times before the motor starts. Anyone with a similar experience?

    Lower unit question

    I blew my lower unit on a J50BELCNR (1982 johnson 50 hp outboard) and have found one on ebay from a 1982 evinrude 60 hp. The 20" transom model fro evinrude does not appear to match the 20" shaft model from my johnson, can anyone confirm this?

    Loud pop when trying to start motor

    I have a 1978 mercury 200 20 hp that i just recieved. It needed a power pack, which i installed, and the motor ran for a little bit before cutting out, but did run. I pulled the carb and cleaned it all out (also replaced the plugs) only to find that the needle valve was sticking closed and no...

    Having issues with my eska carburetor needle valve

    So I am facing some confusion regarding my 1974 sears eska 5hp. The needle valve appears to be incorrect for the motor, but matches dimensions with the one pulled from the carb. The needle, when in contact with the seat, appears too long, so the float is at an extreme angle so it barely fits in...

    Sears eska leaks fuel out exhaust port

    I have a 1974 (I'm pretty sure) sears eska 5hp with an internal gas tank. I got it to run, but it POURS fuel out of the exhaust port when pulling the starter cord and while just sitting there after running. I suspected the needle valve not sealing well so I bought a rebuild kit and replaced the...

    1978 Mercury 200 20 hp power pack

    Two years ago, I fixed up a 1978 mercury 200 20 hp to good running shape then it ended up in storage out of lack of necessity. Now, one of the wires coming from the stator had rotted out all the way into the power pack. Is there a good place to buy a used one? A stock unused pack will run about...

    Need help matching up wiring harnesses

    I have a 1982 johnson 50 hp outboard. I removed it from the back of the boat last year, and wrote down how everything was wired up, but left my list outside and it was destroyed. This is what I'm looking at from the boat connector: purple w/ white stripe purple black w/yellow stripe black tan...

    Johnson lower unit issues

    I have a 1982 johnson 50hp outboard that I needed a new gear case for. I was able to get a new case and rebuild the whole prop shaft/ bearing carrier assembly. I am now rebuilding the drive shaft assembly. There is a few pieces called the "cone and roller assembly" that fit in a cavity around...

    Lower unit distortion

    So last season my 1982 50hp johnson outboard's lower unit cracked. I sent it to a friend who does aerospace welding to be welded, and it was. However, there is ever so slight weld distorition in the rear of the housing that does not allow the transmission casing to seat back all the way, my only...

    Johnson outboard overheat?

    So I pulled the motor off my boat this season to get a lower unit crack welded (a 1982 johnson 50hp outboard) and I decided to run it for a couple seconds without the lower unit to ensure it was running properly (I did the same last night with no issue) and the motor made a vicious clanking...

    50 hp johnson lower unit warped

    So my Johnson 50 hp (1982) had a lower unit crack that leaked all the oil and caused it to bind up. I sent the lower unit casing to a friend who does aerospace welding and had it welded closed. The problem is that the bottom of the output section of the casing (where the transmission goes) is...

    Johnson wont crank over

    So i had a bit of trouble with my starter motor, the brushes and armature grew in resistance after repeated use. So i changed it all. The starter works awesome, bendix shaft jumps and engages well, but fails to turn the outboard (a 1982 50hp johnson). Electrically, it all checks out fine. The...
