The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
I have struggled with this and have taken them apart and cleaned both carbs and rebuilt. New needle and seat and my bottom carb will have the needle get stuck and motor runs like junk on top one. I found out which was not working by spraying fuel mix in carb adn seeing which one would kill...
My motor recently started acting up. Wouldnt turn over or electric choke wouldnt work at controls. But if I used rope I could pull start it adn then shut off then it would turn over with key and choke worked. Is this a sign of the neutral safety switch going bad? I did hear a click and hum...
I know I ve seenn it on here before but cant find it. Looking for a diagram especially for the carbs. I have a spring or linkage I found after motor started acting funny like down a carb not sure where to look for this. Will try to post a pic if I can get camera and all working.
I have oil leaking or seems to be from where my spark plugs are installed in the head. Is this normal? Or is there a problem motor is running great now just not sure of the oil. Thanks.

My dad went to the lake with his boat today that he just bought. We had it running on muffs with no problems, and this afternoon he went to the lake to try it out. Put it in the water and it fired right up pured great he said. Then still in neutral it just quit as if you turned the key off...
Can these motors be run out of the water on muffs??? I only see a narrow strip on the bottom where I normally hook my muffs up to that is only like 1/4 in high by 3 inchs long. Is this enough to suck water from garden hose??
I have a 1972 50 hp Johnson dual carbs. Motor ran fine but had electric choke issue. Fixed that issue and put boat in the water and fired but was sounding real sick. Replaced plugs and ran fuel treatment in the tank and sprayed carb cleaner in carbs while running. Not a whole lot of carb...
How difficult is it to trace an electric choke issue? MIne used to work but now it doesnt have to use manual choke havent touched anything on the motor or controls not sure where to start
motor runs fine but when I shut it off gas seems to leak out of carbs notice it more when the motor is lifted up to trailer. Any advice on what is wrong and easiest way to fix?? Thanks in advance
