    Could it be the timing?

    After I get this coil problem solved, I need to take a closer look at the timing settings on this motor. I'm thinking the misfiring issue sounds like a timing symptom. The plugs look good. If the coils check out(see previous posts), then this seems like the most likely cause. What do the more...

    77 Johnson 70 horse coil dilemma

    I have an issue with my motor. It runs rough and is difficult to get into drive but it DOES get up on plain sometimes but after a LOOONNNGGG and SLOW climb! I rebuilt the carbs, swapped out the reed valves and did my best at a "Link & Sync" but it still runs rough. I decided to check my coils...

    '77 Johnson 70 hp coils

    My 70 horse Johnson is running rough...misfiring and difficult to stay running and get into drive gear. When it does go into gear it WILL get up on plain but it is a VERY slow and steady acceleration. I was thinking that I should check my coils so I pulled them off and checked them with my...

    Reed Valvè Adjustment 1977 Johnson 70

    When open up my throttle to WOT my reed valve are anywhere from (if you think of a clock) 1 o'clock 7 o'clock to 2 o'clock 8 o'clock. Since the roll pins are supposed to be at 12 and 6 at WOT ...where is the adjustment on these? Every video I have seen shows diagnosis and replacement but not...

    How do I adjust the fuel/air blend ???

    3 cylinder outboard engines are a completely different animal to me! It was always simple adjusting my chainsaw...2 screws..."in" is lean..."out" is rich. But 3 carbs all connected by linkage is new to me. I understand how they all run off the center carb and the linkage keeps them in check so...

    Where does this spring go???

    I have a 1977 Johnson 70 hp outboard 3 cylinder. I recently removed the carbs for a good cleani g and when I was finished I ended up with a spare spring, which I assume goes on the middle carb because the linkage runs off the middle carb. I've looked on the schematic and I can't even find the...

    Drain line on Mercury 7.5 hp motor

    I've had problems trying to get my little need to shoot water from the telltale. I got it to dribble a bit but then noticed a short 1/8" id hose that runs from the right bottom side to the right top side and is clamped at each end. The schematic says "drain hose". Question...does this circulate...

    1970s Mercury 7.5 powerhead stuck in forward gear

    I pulled the lower end off and changed the impeller and I don't know if I bumped the powerless shifter or what happened but when I tried to reinstall the lower end I noticed the shift lever in forward. I tried to shift it into neutral so I could SLOWLY turn the flywheel to reinstall the shifter...

    1973 johnson 65 hp and 1977 johnson 70...are the gear cases interchangeable?

    I nought a 1989 Wilker Spirit 4.8 with a 1973 Johnson 65 on the back. Later found out the stator is fried. Bought a replacement stator or so I thought...long story short...I found a 1977 running powerhead on kijiji for $300 and after researching found out most of the electrical is...

    1973 Johnson 65 hp not running on WOT

    I have a 1979 Wilker Spirit 4.8 that I just bought. When I put it in the water I found that it won't run on Wide Open Throttle. I got a local mechanic to look at it and after cleaning the carbs...twice...discovered that the stator was heating up and the insulation on 2 of 3 of the coils was...

    1980 Merc 50 hp won't shut off choke

    This is my first forum...I'm having a problem with my old 1980 50 hp Merc engine. It starts right up on choke and runs great but after about 30 seconds it bogs down and putters along like a 10 horse and goes through gas like the fuel line is leaking! I'm thinking that the choke isn't cutting...
