Bogging down

i am having a problem with my

i am having a problem with my motor bogging down after setting in water for a while no throttle response just steady idle then after a few minutes engine picks up and responds fine

fuel pump or bulb leaking???

fuel pump or bulb leaking???

"What engine? Are you saying t

"What engine? Are you saying that after running awhile, it bogs down as idle?

Or are you saying that after idling for awhile, it bogs down when throttle is applied?"

"on start up motor runs fine g

"on start up motor runs fine go to location and anchor for a while decide to move boat will not throttle up it just boggs down and dies if i let it idle which it does, i can wait a few minutes at this idle than try throttle up and it is fine only until i stop for awhile than try to go again the problem is the same this is a 1982 johnson 70 horse"

"You don't say if you pump

"You don't say if you pump up the fuel primer bulb hard again before that second start. If not, do so. If this cures your problem, suspect the anti siphon valve, explained as follows.

(Fuel Anti Siphon Valve)
(J. Reeves)

Many of the later OMC V/6 engines incorporate a fuel restriction warning via a vacuum device attached to the powerhead. If the engine overheats, or if you have a fuel restriction, the warning is the same.... a steady constant beep.

NOTE... Only the V/6 & V/8 engines have the above "Fuel Restriction Warning". The warning horn will not sound on the other models.

The fact that a engine is not overheating, but the warning horn sounds off with a constant steady beep, and that the rpms drop drastically would indicate that the engine is starving for fuel due to a fuel restriction. Check the built in fuel tank where the rubber fuel line attaches to the tank fitting. That fitting is in all probability a "Anti Siphon" valve which is notorious for sticking in a semi closed position. It will be aluminum, about 2" long, and the insides of it will consist of a spring, a ball, and a ball seat. If this valve exists, remove it, knock out those inner components which will convert it to a straight through fitting, then re-install it. Hopefully that cures the problem.

The above procedure will cure a restriction problem with the anti siphon valve as stated. BUT, it may also allow fuel to drain backwards to the fuel tank when the engine is not running (siphoning backwards) due to the fact that the carburetors/fuel pump etc are higher than the fuel tank. This condition is not an absolute as the valves in the fuel primer bulb usually prevent this backwards siphoning problem. However.... if this does take place, the cure would be to install a new anti siphon valve.
