    My Johnson 120 won’t rev in water

    What spark plugs are installed and do they jump a 3/8" gap using an air gap tester with all 4 plugs removed? That was a big leap to change the fuel pump before verifying everything else. We need to know compression #'s and spark gap results before moving forward. Water in your fuel can cause...

    Trying to identify 2000 Johnson/Suzuki 50 HP (J50PLSIB)

    Is there any oil left in the remote tank? 10 years of running should surely have used up all the oil in the tank. Unless a previous owner bypassed the VRO in which case you should have been running fuel pre-mixed with TCW3 oil at 50:1 ratio. That engine should have had both No Oil and Low Oil...

    1996 EVENRUDE 20HP HELP NEEDED

    This is the first time I've seen MarineEngine.com have conflicting information. On the spark plug page and the "Common Replacement Parts" list, both links show QL82C. But you are correct, when looking under Cylinder & Crankcase it sure does show QL77JC4. I'll contact the admins and let them...

    1993 Johnson 115 VJ115TLETS locking up. HELP

    Excellent advice. If the OP's engine is locking up solid with a lean seize I would be very concerned there is already cylinder wall damage.

    1996 EVENRUDE 20HP HELP NEEDED

    Nope. I went to the MarineEngine.com and the E20CREUM Parts Diagram Page has a link to QL82C "Spark Plug - OEM". The MarineEngine.com Champion Spark Plug Page does not show QL77JC4 for any year of 20HP.

    A lost soul with a newly acquired "0 time" 1958 Evinrude 35 HP electric start outboard motor...

    Here is a link to your parts diagrams --> 1958 Parts Diagrams for Model 25936 In short, yes, it appears your model has an electric choke. The components are on the lower left of the carb diagram that I have circled in red.

    1983 Johnson V4 140 Low Compression

    If you've worked on Jet engines using precision tools, then you can work on this outboard. Just follow the CDI steps point by point and it will either confirm your ignition system is good, or will tell which component (s) is bad.

    overheat ?

    The entire pump kit is $101 for Part #5001594. The impeller only kit is $41 for Part #5001593. If you used a cheap knock off kit, or you've dry run the engine, I would strongly encourage buying the entire OEM kit so you have 100% good known parts. If the last time you used OEM and your...

    overheat ?

    Backing out the shift rod retainer is a bit of a pain, but not impossible. You should be able to drop the lower, replace the impeller, and reinstall in less than 4 hours. This video is a good run down of the LU removal process --> V4 LU Removal from Brandon's Garage

    overheat ?

    Sounds like your water pump is bad. "A few years old" means exactly what? Typically replacing the impeller every 3 years is recommended. If you happened to have sucked in sand and grit it could have drastically reduced the life of your impeller. If you've done dry starts that will really...

    1996 Evinrude Intruder 150 - Runs great on muffs, dies in water

    I have the exact same engine. Compression and spark on your engine sounds like you're good. So you've messed with the timing? Go to this link for some guidance on OIS2000 timing --> MaxRules OIS2000 Ignition. The timing on these is not just a simple straight forward thing. Have you verified...

    1996 Evinrude 150 Intruder starts with choke, but dies.

    With the primer in manual position you are just flooding the engine with un-metered fuel. As Racer said, step one is cleaning cone shaped fuel filter, the VST and installing a new gaskets/O-rings. Have you looked for leaks around the fuel manifold and throttle body on each side? When cleaning...

    Re-start fuel bogging at higher elevations-1989 Evinrude 150hp

    Bogging and wet plugs can be caused by blow-by in the rings (hence the compression test), weak spark, incorrect spark plugs, or a carb flooding the cylinder. As Racer said, verify the compression with an accurate gauge. Use an air gap tester and confirm the spark on each cylinder with jump a...

    Reeds. Metal vs fiber -- sources for replacement parts.

    It's not likely that reeds are your issue. But, if you go down that route Boyesen is a long respected name in aftermarket reeds. In most cases fiber reeds are meant for fast throttle response and more air flow at high RPM, not for low speed operation. Carbs are a very likely source of your...
