So I took the new 1981 115hp johnson and my boat out to the lake yesterday for its epic test run.

The primer cylinder on it is missing, so I plugged all the hoses with screws until the new primer cyl. gets here.

I started it in the drive way before we left, took a few seconds but started, and after it started once, it continued to start just fine.

Well, about an hour after driving around, I shut it off to take a swim. Then wouldn't start back up.

So I took the screw plugging the fuel line into the primer out, and stuck the line into the carb cover, as to give it gas. It would fire for a second then die. about and hour later of this. I gave it one more try and it started right up, where i hauled butt back to the launch.

Now the lake police were hanging out near the empty launch, so i couldn't full throttle it in the no wake area, so i throttled down to were it was at idle, yet in gear, and it died and didn't start, so i swam it the rest of the way to the dock.

what could the problem of been?

Re: ran great until an hour of driving, then wouldn't start.

Fire w/primer, die w/out
Won't idle, dies

Acts like little to no fuel thru the idle jets

Something has gotten into those carbs, dirty fuel, water

Another tear down and cleaning

Replace or install inline filter/water seperator
