    J120TRCUL sounds like it's running on 2 cylinders

    I have checked compression, all within a couple lbs of 120, replaced all 4 spark plugs and coils, not the wires yet and still get the same issue. Some times it will start and idle fine and then it will start missing and sometimes it will start up missing. It is almost positively running on the...

    J120TRCUL fuel pump leaking?

    Working on a friends boat, when I press on the fuel bulb gas leaks out of the very top of the fuel pump, more on the oil pump side if that makes sense. I think the needle in pump that lets the gas in is leaking or something. Is that normal or is that something that can be fixed or does the pump...

    1987 J120TLCUR carb help

    I have been working on my friends boat for him doing the carbs when I found that 2 of the plastic elbows for the fuel lines were broken. I took off the carbs and pushed the rest of the elbow out and got it out of the fuel line, how ever I can't seem to find a part number for the elbow. It's a...

    help with an 88 spl

    I just recieved an 88 spl from my grandfather. Its been sitting for 4ish years, but it started right up. It idles fine and all, but since its been sitting, I want to do the impeller. Its nothing like my 1978 115 where you just unscrew the shift rod screw to drop it down. It looks like some...

    1978 115 siezed today

    I was going WOT, after crusing at about 3.5 mph for 30 mins, and all of a sudden i lost power. It felt exactly like it did when my other 115 blew, 4 years earlier. So i slowed it down, hoping to limp back to the landing to pull it out of the water at least. It siezed as soon as i cut back on...

    johnson/evinrude 1978 problems/questions

    i put a 78 evinrude and 1979 johnson 115 hp together. The lower unit and electronics from the 79 went onto the 78. It started right up and ran well.

    about to wake a sleeping motor

    I read the FAQ, and i've done everything in it. I replaced all the electronics, cleaned it up nicely, and changed the spark plugs. I will squirt oil in there before i start it, but its been sitting in a shed for 4-6 years. It spins by hand, and it builds compression, so im just waiting to turn...

    Stator question

    I have an old stator that was on a motor that was running until a piston ring broke, but upon inspection, i noticed it was cracked at the top and seemed to have melted and leaked out black plastic out of it. I know the engine overheated at one point, and it was hot when the ring broke, but would...

    I have either a 1977 or 1979 johnson 115, ( i forgot which, its the opposite of the boat). Anyways, about 4 years ago or so, the engine was running terrible, so i pulled the heads off, and low and behold a ring had come off and smashed up inside the cylinder wall. I was wondering at what i...

    I had a problem last year right at the end with bad gas, so i cleaned the carbs and i got a new fuel pump. This year i had fresh gas, and it started up, idled a little rough but smoothed out, and i was able to get it into gear ( all in my driveway) before it would over heat. So i bring my boat...
