    Proper tell tale location for my Johnson V-4

    Another one of my winter projects is adding a tell tale to my '67 Johnson 80hp. I'm doing for two reasons...First: to eliminated air pockets/hot spots in the water jacket. Second: I'm tired of running along on the water and periodically having to ask my son "can u see water coming out of the...

    Are all tilt tubes the same size?

    I just installed a new Uflex Racktech steering system in my "67 Glasspar and I've just realized that the original tilt tube will NOT fit the new cable. This old tube is threaded on the INSIDE and the new cable has a nut that threads onto tilt tubes that have threads on the outside of the...

    Proper fuel line diameter for my 80hp?

    I'm currently using 1/4" ID fuel line for my '67 Johnson 80hp motor. I went to buy a fuel tank connector for the portable tank I bought and noticed that all the connectors seem to 3/8ths or larger, so I started to wonder if my fuel line is too narrow. I checked my service manual and can't seem...

    Which is better fuel tank placement?

    I just removed the 15 gallon metal bow mount tank out of my 16' Glasspar Avalon. It took up too much space under the bow and made the leftover space under there unusable. This is a view of the bow now that the tank was removed. (Ignore the junk I put in there) I plan on using a 6 gallon...

    Uflex rotary steering system...what else do I need?

    I'm going to be purchasing a Uflex rotary steering system for my '68 Glasspar. I don't know what I need(if anything) at the stern of the boat to attach the cable to my '68 Johnson. I currently have the original rack system on the boat right now and I need to know if any of the components are...

    Tiny Tach for my Johnson V-4 ?

    I've finally decided to get a portable tach(probably a Tiny Tach) for my '67 Johnson V-4 80hp...and I don't know which one I need. I've searched here, but I'm still not sure which one is right for my motor.

    Why is my Johnson 80hp hard to restart ? (Updated)

    The motor starts easily and runs very well. It idles smoothly and will remain idling well even when RPMs are very low. Points, condenser, plugs, and coil are new. The problem is that it's hard to restart after I stop the motor to fish etc. Sometimes it starts right up, but dies after about 5...

    Is this "brand new" OEM Johnson coil still good?

    I'm thinking about picking up this "brand new" OEM coil for my Johnson 80hp. http://www.ebay.com/itm/190565793308?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649#ht_500wt_922 Is this coil likely still good? Or can they simply 'go bad' after sitting for so long?

    A/C Delco spark plugs okay for Johnson 80hp ?

    I'm currently using A/C Delco R43S plugs on my '67 Johnson 80hp motor. I couldn't find Champion J4J or J4Cs locally. NAPA says that the A/C Delcos were the same as the Champions, but I'm having doubts. I read a thread where it was stated the plugs with the letter "R" in them meant resistor...

    Started the decarb on my 1967 Johnson 80hp tonight (see video)

    After doing a ton of reading on the many different decarb procedures...I decided that I wasn't going to wait any longer. (Talked to PO and he had never done a decarb on it) Warmed up the motor this morning then pulled the plugs and heavily sprayed each cylinder(at TDC) and let the motor sit...

    Is this decarb procedure ok for my Johnson 80hp?

    Now that my motor is running on all cylinders, I think it's about time that I decarb it. I've been reading tons of threads on the subject, but want to be sure that how I plan to decarb it...is acceptable. Going to warm the motor up on muffs. Then I'm going to mix up a gallon of premix and 3/4...

    Is this fuel contaminated? (see pic)

    I emptied out my bow mounted fuel tank last week(had 18 month old stabil treated fuel in it). I looked in the tank with a flashlight and didn't notice any rust etc(but I can't see too far left and right of the opening). I replaced the fuel line and installed a clear fuel filter like this one...

    1967 Johnson 80hp backfires when I mist fuel into carb

    My #2 and #4 cylinders are still giving me problems. Motor starts right up(on only 2 cyls, I think). I pull the #2 plug wire and engine doesn't stumble....same for #4. I sprayed premix in the starboard carb throat(this carb feeds #2 and #4 cyls on the port bank) and the motor backfires(a loud...

    Need help to set points on Johnson 80hp (Manual is confusing)

    I've been reading my service manual on how to set points, and I'm not sure I set them correctly In the "d" section of instructions it mentions "The breaker point arm opposite the condenser should be on the high lobe of the cam" It then immediately explains in section "e" to loosen the...

    Torque specs and tightening pattern for 1967 Johnson 80hp?

    I asked this question in my "stripped spark plug hole" thread, but it turned into a "Time Sert" discussion. My head gaskets are arriving tomorrow(ahead of my service manual). Anyone know the pattern I should tighten the bolts? And to what torque?

    How to test coil and condenser on 1967 Johnson 80hp

    I finally ordered a service manual for my motor, but it won't arrive til Monday or Tuesday. I'd like to get some testing done on my coil and condenser in the meantime. Going to pick up an auto-ranging multi meter tomorrow (shame on me for not having one already) I'm an electrical noob, so...

    Stripped spark plug hole.....Helicoil or swap head?

    While checking plugs I noticed that my #1 cylinder spark plug hole is stripped. :mad: I def didn't do it...I'm guessing that the previous owner probably cross threaded it and weakened the threads, since there is another helicoil installed on the #4 cylinder. Anyone know how difficult it is to...

    '67 Johnson 80hp. Dropped 2 cylinders.....AGAIN!

    Guess I should start a new thread cause my motor isn't bogging anymore, now I can't seem to keep the port side cylinders running. Quick overview: Compression is 90psi across the board Starboard cylinders are running fine (I pulled plugs one at a time and engine stumbles/dies) Port side...

    Johnson 80-85hp owner's.....What speed you getting out of your motor?

    Before I even bother trying to get more speed out of my '67 Johnson 80hp motor, I need to know approx what speed this motor is capable of. My 15' Glasspar weighs 675lbs, motor 240lbs, gear/fuel/me 310-ish lbs.....and I'm getting a max speed of 33mph w/ stock prop. If this is normal, I'm fine...
