    'about at my wits end!!

    My 77' Johnson 140 won't start! It cranks over but won't ever fire up - not even a cough. It left me stranded a couple of weeks ago and upon inspection found what I thought at the time was the problem, the stator had oozed and leaked in a couple of places so I ordered a new one - mucho bucks...

    Johnson V4 stator

    I'm needing a new stator for my motor '77 Johnson 140 hp with TnT. My parts catalogue calls for a 12 amp stator. I've researched the internet and have only come up with a CDI/Rapair brand. Are these good stators? Anyone know of any other makers of this particular stator? I couldn't even...

    A little background first. Motor ran great at any speed except idle and was a little hard starting so I removed the carbs and cleaned and rebuilt with carb kit. Linked and synced according to the OEM manual. Motor started pretty good and ran on muffs. Took it to the lake and started first...

    Is there a way to determine if the T/T gauge is fried. It was working fine last season - I had trouble with the T/T earlier this season and ended up replacing the solenoid and checking/cleaning wiring connections in the "Black Box" which houses the solenoid and multitudes of wire connections...

    The parts breakdown shows a picture of one carburator (the upper or lower, I'm not sure)they're both the same right? My question is: it lists a carb kit, is this for just one set of carbs or both?

    WOT rpm & overheat horn '77 Johnson 140 hp

    What should my WOT rpm be on this motor? I'm not sure what size prop I have - is there a way to measure it somehow? The motor is mounted on an 18 ft. Glastron trihull skiboat. Also, I grounded the tan wire on my overheat sensor and made the horn blow. Is this verification enough to know that...

    Thermostat change 140 hp

    I started my motor and was feeling the temperature of the heads with my fingers. I noticed right off that the starboard side was getting alot hotter than the other side. I could leave my fingers on the other side for several seconds and only maybe one on the starboard. I think it's probably...

    '77 Johnson 140 hp water pump/impeller replacement

    I've never replaced my water pump and/or impeller on my boat (I've owned it for 14 years). From reading all the posts related to this subject it looks like I probably should - even though they seem to be working fine. I don't own a service manual, could someone tell me the basic steps involved...

    My trim motor operates in the down position but not in the up. I have an up and down button on my throttle to contol the trim. I have filled it with fluid. I hear a dim click at the solenoid when I press the up button. I've cleaned all the wires in and around the solenoid and still no up...
