    Will 125 HP heads fit on a 115?

    Ive got a spare 1979 115HP I want to build as a 140 spare engine. I'd like to get the compression up a bit though and 140 heads don't seem to be growing on trees these days. Will the earlier 1972 125HP heads bolt up to the later block and have enough piston clearance? I know I'd need to make...

    What 2 stroke oil do you like?

    Ive been running Penzoil to get the new 140 broken in but I'm about to swap to synthetic. Ive got a gallon of Royal Purple 2 cycle. I might pick up a gallon of amsoil just to see what the fuss is about.

    Destroyed my new prop. Not quite a tragedy.

The company buys me a tank of gas and a gallon of oil . Good deal for them and for me and since I'm the guy who signs off...

    Boaters Insurance

    In 30 years of boating Ive never had boaters insurance. For most of that time I never even knew it existed and Ive never lived anywhere that required it. I did go to a private lake in California that required it once but thats the only mention of mandatory boat insurance Ive ever seen or heard...

    Best prop Ive ever used

    Ive used a dozen or so props over the years of different types looking for the best performing prop for my boat. Ive got a 17 foot 1981 Checkmate Enticer with a Johnson 140 crossflow V4. Its freshly rebuilt and is in top form. Best speed Ive had it going was 60 mph GPS with the motor all the way...

    Autolite 2634

    I generally run the Champion QL77JC4 in my 1981 vintage but recently rebuilt Johnson 140 crossflow. They riun fine but I do live out in the middle of nowhere and they are slightly difficult to get. I can get the Autolite 2634 a lot easier and I know the original owner of the boat ( dad ) used...

    90 to 140 conversion.

    I'm doing a 90-140 HP Johnson V4 conversion. Some people say thats a bad idea and I wont notice a difference. That sort of talk give me blank stare syndrome. I've been behind the wheel of a few 140's and the 90's are nice engines down low but really run out of steam on the top end. I want top...

    1985 Johnson V4 ignition wiring

    I replaced the port side CD pack on my 81 Johnson 90 HP with a power pack from a 1985 with coils to match. The power pack was cheap and it already had one post 85 slip on connector coil on it from a previous fix job somewhere although the old man swears he doesnt know how it got there. There is...

    Will 1975 vintage 115 HP heads fit on a 1981 vintage 115 HP Johnson 4 cyl

    Will 1975 vintage 115 HP heads fit on a 1981 vintage 115 HP Johnson 4 cyl cross flow? Will they bolt up and work? I realize the compression would be higher but would it be too high? The coils would have to mount some other place but thats not a big deal. Is it do-able? I want to raise my...

    90 Johnson to 140 spec conversion

    Ive got a 1981 vintage 90 Johnson. Great Running motor. Been on the boat ever since my dad bought it new in 1981. ~125 psi per hole compression. Great engine. He gives it to me and of course I have to take something sweet and make it dirty. Anyway, I want to do the 140 HP conversion. 120...

    Johnson 90 shift and throttle retainer

    Ive got a 1981 Johnson 90 on my Checkmate Enticer. I'm in the process of rebuilding the boat and Ive run into a small snag . The motor seems to be missing the cable retainer or retainers where the cables come into the motor housing. The original owner ( dad ) seems to have lost it and the cables...
