I haven’t posted in a while, but have a motor problem that I could use some help with.
For a variety of reasons, I didn’t get out on the water this summer. I have cranked my motor (1996 112VR Johnson) every month for good measure. When I had the boat (180cc Seapro) on the earmuffs yesterday, it cranked fine and ran great for about 5 minutes. I was about ready to shut it down, when it began to rev a little faster, then sputtered and a bunch of tan colored sludge came out of the prop exhaust.
I checked the bulb, which was soft, tried to pump it up, but it wouldn’t get hard. I checked the fuel water separator. The fuel level was halfway down the canister. I put some mixture in the canister and re-fired the motor successfully. It ran great until it shut off again in a couple of minutes. Once again the bulb was soft and I had to refill the canister and refire.
This cycle repeated itself a few times. I can get the motor to run until the separator level falls too far, then the motor is starved for fuel and shuts off. I try to pump fuel manually, but it will not draw from the half empty container.
sounds like the pick up in your tank is cloged! Try takeing loose intake line to filter and blowing back in to tank! if no blockage you will hear bubbles in tank If blocked try compressed air if it dont work, unhook line at tank and un screw tube ck filter at bottom might have to take off screen and clean. I once had the entire screen sucked up the tube and compleatly blocked off line Had a hell of a time removeing it 50 mi. off shore. Also ck for dirtdobbers in vent line try to blow thru it also clean out with close hanger!
Boatpoor is dead on. Another thing I learned recently is the barbed elbow on top the tank could have an anti-siphon ball valve in it that will sometimes get stuck and crush the primer bulb, restricting flow.
I’ve had similar intermittent issues and had success disconnecting the fuel line from the filter and blowing into the tank just as BP described.
My fuel pump is only 3 years old, so I would be surprised if it was that. I like the idea of hooking up to a separate fuel tank. I’ll try all the simpler stuff first.
