Motor stalling on the water

[chadderkdawg]

Took the boat out for a shake down run this weekend, had recently rebuilt the carb, and found the anti-siphon valve broken at the tank. I replaced the anti-siphon with a regular barbed fuel connector temporarily and was able to get the boat running. Also attempted to replace the fuel filter but NAPA failed me and the replacement I got didn't work, so the old one went back on. Anyway, onto the problem.

We got in the water, idled around for 10 minutes or so until I was pleased that the motor was running well. Started to give it some gas, was doing great through about 2000 rpm, got up on a plane and the thing took off like a rocket, was running really strong. After maybe a minute at 2500 the motor stalls out and we nose dive. I was able to get the motor started after 5-10 seconds of cranking and turned around to idle in. The boat died 3 more times while idling in, and it became harder to start each time, the last time just barely sputtering to start. We did get off the water under our own power, when I pulled the plug from the bilge there was easily 2 gallons of new water, which concerned me because we were only on the water maybe 20 minutes....

I don't really know where to start with this one, any suggestions are welcome, thanks everyone.

Ayuh,..... It sounds like yer fuel delivery issue still isn't fixed,....

Donno where the water came from,....

Were any drain plugs pulled last fall, replaced this spring,..??

Fuel delivery is still my first thought too, new filter and antisiphon will be here tomorrow., Not sure about the plugs, only been my boat for about 2 weeks.

Let me add this, the other day I felt that the ignition coil was really hot, but I didn't think a lot of it. I cant confirm that it was hot when the stalls happened though, I'll try and test that this week. Would a faulty coil cause stalls like I had?

gonna bump this before it falls off...

Pulled the old fuel filter off and replaced, poured the gas out and it was filthy and had some fuel at the bottom as well.... Replaced antsiphon, and replacing coil and spark plugs tonight. Also going to drain the fuel tank, please speak up if you have thoughts, we are hauling the boat about and hour and a half this weekend and really want to have a great weekend.
