Just bought a 2006 GTX Limited 215 and it has a stalling problem at idle on occasion, when jumping or hitting choppy seas, and also when idling down from speed. It will usually rough idle until it kills. When I restart it though, it runs fine??? I thought it could be fouled plugs or bad gas...

I have a 92 GTX with a 587 motor. I had the carbs rebuilt a month ago because it ran a little rough. It starts and runs in the water just fine, full power and on plane. After it gets hot, it goes into a cycle of bog, rough idle, full speed for 5 seconds, bogs down, rough idle again, full...

55 hrs, new plugs. just above idle runs rough with alot of surging until about 1/3 throttle, then runs fine with good power. Tach does not work, so I can't give exact rpm. Any ideas? thanks.
