    Water in cylinder 15hp '75

    Replaced impeller/thermostat recently, and upon next run wouldn't idle well. Checked plugs and found water on lower one. Pulled head, and sludgy looking watery/fuel mix found in both cylinders (more in bottom one). Replaced head gasket w/no improvement (water still evident on plug). I have...

    '58 3hp JW-14 Flywheel nut and key

    New to me.. No flywheel nut, and gummed up key and cam (crank is good). I have a spare cam, but no nut and key. Anyone know the size of the flywheel nut and key? I'm thinking just a trip to the hdwr store... Thanks!

    '56 Johnny 15 FD-10 carb vent

    Is there a normal vent in these carbs? I prime the 2-line system at the tank, and fuel immediately gushes out the brass nozzle tube into the carb. If I blow through the fuel line into carb inverted, no flow. Good. Upright, air through, but not if high speed jet is seated. Is this right...

    9.9/15 hp info

    Anyone remember that all-encompassing website for these motors? I misplaced the link, and can't remember what it was called. Was just for 9.9/15 hp Johnnyrudes. Thanks!

    pressure tank primer

    Tank works fine, holds pressure fine, but when I use the primer button, it leaks fuel from around the shaft. Only leaks when priming. Is there an o-ring I need to replace? I take it I'm going to have to pull the whole assembly off the metal tank itself to service. What are the odds that I'll...

    '74 evinrude 15hp gear jump

    Buddy's motor said it sounded like he hit a log at speed, similar to what an older 18 would do w/bad clutch dog ears.. He says it doesn't do it at trolling speed, but now it's about every 10 seconds at higher speeds. I changed out the gear oil, and it looked fine. Am I correct that the clutch...

    '75 15hp stator plate wobble

    Electric start motor w/charging stator. I tried using a punch to 4 spots around the motor boss and it worked briefly, then sloppy again. I've resorted to opening the points a bit for the lower cylinder and moving the charging coils back behind the normal placement just a bit to keep it from...

    15hp '75 gearcase access

    I need to re-seal my lower unit, and I need to pull the access cover/bearing carriage from behind my prop. I remember seeing that someone posted how to make a puller to get that off. I can't seem to find it now. Can someone steer me in the correct direction? It's the type that came after the...

    10hp starves for fuel.. 2-line system

    qd-20 10hp, pressure tank system. Great spark, good pressure tank system and fresh fuel. Primed carb w/primer on tank and it starts fine, but dies due to starving out of fuel (sneeze). Even at higher rpm's than idle, where the low speed side wouldn't matter if it were clogged up (it should...

    broken shift handle '72 20hp

    The handle is gone, and it broke off at the shaft about 1/4" inside the housing. I'm assuming I'll have to remove the powerhead to get at it. Any advice? I'm sure once I remove the powerhead, removal and replacement will be self-evident. I'd just hate to find I didn't need to remove the...

    Fuel/oil ratio for a '64 3hp JW-19A

    I know J/E switched from 24/1 to 50/1 right around that year, but I can't recall exactly. Anybody sure of the answer? Thanks!!

    sportwin idles fine at 3/4 choke

    '72 9.5 evinrude. Spark is fine, ran well, but coughed at idle (couldn't adjust it 'rich' enough on low speed setting). I assumed it was the low speed o-ring (packing) and replaced.. same symptoms. I just put in a carb kit (and replaced 0-ring again) and it runs the same. I soaked the carb...

    15 johnson 1975 electric start spark quandry..

    This is the one w/a trickle charge, and points ('74-'76). I have a spark tester, and no/very weak fire on lower cylinder. Disabled kill switch connectors, and inspected the rest of the wires(2) to the connection w/each coil and point set. I am sure coils/condensers/points are functioning for...

    25hp johnson '85 cuts out at 2/3 throttle

    Any clues? I'm reposting from a couple days ago: '85 25hp johnson manual start motor runs perfectly, but when powering up in gear at about 2/3 throttle, it simply cuts out. I can keep it from shutting completely off if I reduce the throttle quickly, and then it 'catches' again. It seems to be...

    25 johnson 1985 cuts out at 2/3 throttle

    '85 25hp johnson manual start motor runs perfectly, but when powering up in gear at about 2/3 throttle, it simply cuts out. I can keep it from shutting completely off if I reduce the throttle quickly, and then it 'catches' again. It seems to be ignition cutting out altogether on both cylinders...

    '52 5hp tn-28 impeller

    I need one. My marine guy couldn't find a brp or sierra replacement. He got one for an old evinrude 5, but it was for a slightly smaller shaft size. I'm out of ideas. And the old impeller is intact, but trash. I could probably find a used one, but what's the point?

    johnson 15 15E75C seems to lose spark on one intermittently. it winds out fine, but just seems to lose 1/4 power for a few seconds and then runs fine.. and cycles like that. It's elect start, and I replaced one set of pts and cleaned the other. Carb should be good, and I tried...

    25hp evinrude '78 no spark after warm.. help

    I've got a 25hp electronic ignition '78 manual start Evinrude. Totally loses spark after about 10mn and comes back briefly, then no more for a long while. Definately a spark issue. No overheat (can grab cylinder head for a brief time-normal, and good telltale and newer waterpump and tstat)...
