    Can a Mercury switchbox be repaired?

    The one that is on the 1987 9.9 two stroke is actually badged CDI. It is not firing the top cylinder and is going to cost me an arm and a leg to replace. I don't see there is a "core" charge so I will get to keep the dead one... my question is; can the plastic in the back of the thing be dug...

    how do I know (for sure) if a coil is not working (1989 9.9 two stroke)

    I have had trouble periodically with this motor for the last few months but had not located a fault till today. It will not start without advancing the throttle by hand (by pulling forward on the cam follower) and even then it runs poorly, missing as though on one cylinder. Having noted that I...

    no fuel getting past the fuel pump on 1989 9.9 2 stroke

    The motor was working like a charm in June, then I took it off and set in on a stand by the dock and ran my 1987 Johnson 9.9 all summer; I keep the two motors so there is always a back-up. This past weekend I switched motors but could,'t start the the Merc, not even a pop or fa?t out of the...

    92 90 Johnson VRO ran HOT for a minute then OK in tank

    The shop I purchased this o/b from was demonstaring the engine in a big tank at the rear of the building to show me the "no start" condition was fixed (new powerpack was required). They had backed the boat/motor/trailer to the tank and lowered it in with the tilt. It was running pretty good so...

    1980 Johnson 9.9 water jacket gasket #$%@**&^%$##@$#%

    OK...I'm a little frustrated.... I decided to change the head water jacket gasket just because... anyway I'm second guessing that decision since I CAN'T get the plate off. I removed all but the lower right bolt (it won't come out; not enough wiggle room) so I followed the instructions and tried...

    1980 (ish) Johnson 9.9 running cool

    I bought a 1980ish 9.9 locally and although it runs great I've noticed that no matter how long it runs in a garbage can, even in gear at moderate throttle the tell tale water stream never even gets lukewarm. I measured the temp at the top of the head and at the back of the head water jackets...

    Which Evenirude/Johnson oil to use in 90 hp VRO?

    XD 30-50-100... I will be breaking this engine in after a rebuild and was wondering which one to use. i know that I should run the oil in the tank and a premix of 50:1 until I confirm the VRO is working. Should that be with the sythetic because its a better oil (is it?) or is one of the other...
