    Lower unit reassembly

    Stick with it. You'll get better at the each time you work on them. last 2 lower units i've dropped. I've had the impeller replaced and back on in under 15 minutes. 3 or 4 months ago i would've laughed at that.

    Jet Engine vs Mud motor

    After a full year of using multiple outboards at the river I am finally ready to admit defeat. A standard outboard motor isn't the best option for me in the rock bed shallow river I frequent. I am going to get either a mud motor or a jet motor. Does anyone have experience with both and which...

    1976 Johnson 6 hp no water coming out of exhaust

    Friend of mine just replaced the impeller, so I didn’t inspect things. He said impeller passed the bucket/drill test with flying colors. On full throttle I can get the water to shoot out thermostat housing a good 4 feet in the air, so it’s pumping like a champion.

    1976 Johnson 6 hp no water coming out of exhaust

    I feel the same way. I I thought it might be either the upper (power head to brass tube) or lower (brass tube connects to water pump housing) water tubing grommet, but if those were melted/in poor shape motor would not pump like a geyser our of thermostat housing correct?

    1976 Johnson 6 hp no water coming out of exhaust

    I decided to get a back up motor after not being to fish for several weeks due to problems with my 15. I bought this 6 hp long shaft for $100 and was told it wouldn’t pump. New water pump and still no water coming out of exhaust. Water pumps great from water pump to thermostat housing (see...

    1990 15 hp Johnson won’t start, sort of sounds like it’s sucking air/leaking air

    Update on this mess of a thread. Motor starts and runs. I cleaned the carb and put on a new fuel pump. Seems to have resolved everything for now. I think high speed jet was clogged up.

    1990 15 hp Johnson won’t start, sort of sounds like it’s sucking air/leaking air

    Since I had the wires backwards, how was I still able to see spark in bottom cylinder it it’s supposed to be dead? Does it have to do with my gap testers being in place?

    1990 15 hp Johnson won’t start, sort of sounds like it’s sucking air/leaking air

    This is the best explaination I’ve ever seen for this! I’m saving it to my phone tank you! As far as the wires being crossed I only checked the black wires to make sure they didn’t go to the wrong cylinders. The orange wires didn’t even cross my mind.

    Once again racer is always right. That’s rule #1 I need to follow. This is exactly right! I got it to cough this morning. I had the orange wires with the blue line and orange with green line backwards. Spark problem that I caused fixed! 😱. Now I’ve got a motor that quit running acting like it...

    Folks i sincerely do appreciate all your help. I am happy to admit that I am a complete moron when it comes to these motors. I’m willing to take on advice and learn. Sometimes when I get 10 people with 10 Opinions it’s hard to decipher which route to take. I know the very basics of trouble...

    1990 15 hp Johnson won’t start, sort of sounds like it’s sucking air/leaking air

    Thanks for your help. I am honestly not sure what the proper tests to do from here. I have minimal experience with key ways, so I wouldn’t know if it was broke or not.

    I also have the blue/orange wire on the bottom I think: I’m at work not but will check when I get home.

    1990 15 hp Johnson won’t start, sort of sounds like it’s sucking air/leaking air

    I didn’t know that hitting fuel directly into the cylinders means that it’s not a fuel issue tbh. First time I’d ever done it, and wasn’t really sure of the logic. I was just doing what was suggested from another poster. I don’t know what diagnostic tests to do to check timing.

    1990 15 hp Johnson won’t start, sort of sounds like it’s sucking air/leaking air

    Purely novice It will jump about a 3/8” gap. I haven’t tried a 7/16” gap. Happy to try tonight. I’ve never heard of a DVA test so I haven’t done one. My compression is 96/100
