Hey guys. Okay, last year I had a starting problem with my boat. She would engage for a few revolutions and then die. Ended up having a bad ground inside the central computer. Had that changed.
Now, the motor won’t start again but I stumbled upon a “fix.” I can restart the motor by putting the throttle up (disengaged of course) and having someone pump the priming bulb while I crank her over. I let it run like this for 30 seconds and she continues to run just fine.
I noticed two trips ago that my fuel filter was only about 2/3rd’s full when trying to restart it once. When we force fed it gas, it filled back up and seemed to run fine. Not sure if the two are connected, but figured I’d mention it.
Also, I had a few times where the motor would “bog down.” It would settle some, in the RPM. I would have to come out of the gas, bring the RPM’s down, and then push the throttle back up to get back to the power I was after. One time it wouldn’t let me get above 3,000 RPM. I kept bringing the throttle back and forth and it eventually “reset” itself and gave me whatever power I wanted.
I was thinking that was one of my possibilities. Is there a good way to check for a leak? I’m used to checking for leaks meaning there is something coming out of the hose, not going in.
Can be tough to find the leak sometimes. A lot of times one just has to start checking, loosening, retightening hose clamps and fittings in hopes of curing it. Sometimes a hose clamp will cut into a hose a little if too tight, can be culprits, or anywhere a chafing situation might occur with the fuel line. Sometimes just cutting off a inch or two of the fuel line and reclamping can solve air leaks.

Sirecks, I’ll bet if you tell your C17 Crew Chief that you have this problem and suggest a fishing trip for the crew, he will find that leak PDQ! Just saying! Even trade! Win, Win, but you have to supply everything!
I was working on a 70hp rude that would plane out then drop back over the hump. Choke or prime it and it would pick back up. Replaced complete fuel line and primer bulb to solve problem. My 88’ 110 johnson would act crazy like yours and found connector at motor was bad and primer bulb leaked where ends were clamped in. If you have a separate oil tank check it real good for water while you’re checking. My primer bulb was between tank and filter which was not letting filter stay primed.
Well, today I tackled the fuel lines. I trimmed all the ends that I could find. I then disconnected the fuel line that runs from the fuel/water filter up to the motor. I stuck that end in a gas can full of gas, squeezed the primer bulb a few times until it went rigid from sucking the gas out of the fuel can. I then capped that end of the line with my thumb, and after filling the gas line up completely with gas I reattached it to the fuel/water filter end. The motor cranked right up. Shut it down and restarted it about 4 times, primed it each time and within three squeezes of the bulb, the bulb would go rigid and the fuel filter would be full. Somehow, I think there was just air in the line and I seemed to have gotten it out. We’ll have to put her on the water to be sure, though.
