    fouling plugs after decarb

    hey everyone, I just did a decarb on my 83' 140 rude(per the decarb instructions found on this site). It was running great before the decarb. Now it won't run 5 mins before it fouls the plugs and stops running @wot . It just bogs down. I can pull the plugs and clean them and it will run another...

    spark problem, but I don't know where to look

    79' 115 johnny. good compression (around 125 on all), new plugs, new fuel lines and fuel pump, carbs rebuilt, new stator, all 4 wires will jump a 7/16th in gap. Motor will run on muffs until it warms, then I lose the top two cylinders. I can spray premix in the lower carb and it will bog. I...

    No fuel pump kit for 1979 johnny 100?

    Hello, I've been doing some searching on fuel pump kits for a 1979 100hp johnny. I can't seem to find a rebuild kit for it. It is the origional pump and I bought a kit from Iboats that was said it was for a 85, 115, 140 (iboats doesn't list a 100hp online). The gaskets in the kit are just an...

    my newest outboard problem

    Well, my 1979 jhonny 115 has been running great. All of the sudden, it starts missing at idle. It seems to be ok at higher rpms. I cleaned the carbs. A few things I've noticed is that 3 of 4 plugs are wet. I'm guessing it's a low spark issue. I pulled the plug wires off and they all have spark...

    converting a johnny 115hp to a rude 140hp

    I have a good complete great running motor from a 79' johnny 115hp and a 81' 140hp rude with low compression. Is it possible to take parts off of the 140 and put on the 115 to make it a 140? I'm guessing heads, intake, carbs??? Anything else? Thanks for the input.

    Reccomend me a prop size/pitch please

    Hi, I have a 1980 skeeter wrangler 16ft semi v bass boat. It has a 79' johnny 115 (it used to be a 100hp before I swapped powerheads). I'm guessing I'm looking at about 1200lbs. and it runs 44mph WOT (gps) @6200RPMs. I'm guessing that's a little high for several reasons. 1) this was measured...

    Tach reading wrong... or motor not right???

    Hi, I just put a new faria tach on my boat. The motor has been rebuilt and is running great. I am satisfied with how it is running (1979 johnny 115) This Faria tach has 6 selectable positions. I turned it to position 6 and at WOT it reads 3600RPMS. So I'm thinking that can't be right, so I moved...

    rectifier charges but tach doesn't work...

    First of all. I have read all tach related posts...I'm at the end of my rope on this one. 1979 johnny 115. My tach hasn't worked in years, so I bought a new one (faria). I installed it thinking the old one was just bad. I replaced the rectifier 2 years ago because the battery wasn't charging...

    compatibility 100hp to 115 powerheads

    Will a powerhead from a 1979 115hp johnson fit onto a 1979 100hp johnson lower unit. And can I use all of the electrical and carbs from my 100hp? I have a bad 100hp powerhead and I found a 115 for cheap ready to go. Thanks for your answer.

    100hp johnson what to do???

    Ok, here's the deal. I have a 1979 johnson 100hp (javelin? what does this mean anyway and are the parts the same as a non-javelin?) It had been lightly used over the years, and it was used a lot last summer with no problems. This is my situation: Last weekend it broke a ring which in turn...
