Hello all,
Had the boat out today after fixing an overheating issue. I replaced the t-stats and the pressure control valve (spring, grommet and valve), ran some salt-way for four days to take out all the gunk i found after removing the t-stats. I came short from removing the heads covers and cleaning them. The boat ran fine for about one hour. I had her cruising at 5000rpm and topped her at about 35mph (not sustained).
When i came to the no-wake zone near the landing, after i slowed down, the engine bogged down and shut off. I tried starting her out a few times and it cranked, but would not stay firing. I tried pumping the bulb while starting her, but it still wouldn't stay cranked. Got towed back to the landing and now i am home. This is what i have done so far:
-Had a drink
-Checked the lines, no leaks.
-Checked and replaced the fuel/water separator. No water in the fuel, some corrosion on the lip and inside, but nothing too major.
-Disconnected the line coming our of the fuel pump, turned the key, and fuel came out.
Past issues:
-I did have water getting into my fuel tank, but that was fixed by draining the tank, filling it with clean fuel, and adding alcohol-based additive to dissolve the water. The water was coming in through the fuel tank vent hole. I fixed by adding a flush vent hole, a longer hose, and making a loop.
-Because of the water issue, carburetors were pretty gunked up, so I had them cleaned.
-As i mentioned earlier, the overheating issue was dealt with.
Notes:
-When i pump the bulb, it is not getting hard. So maybe a fuel feeding issue?
-Someone recommended spraying some fuel in the carbs to spark it...not sure about that.
Even after i did all that, the same issue. I crank it, and it start for about 2-3 seconds and then shuts off. And yes, the fuel tank is full (that was my first thought).
I appreciate any comments or recommendations you all can provide.
Cheers!
