I recently purchased a 2 year old Sanpan pontoon with yamaha 115 ob. engine has 50 hours on it. At intermittent times the engine will be running very smooth and suddenly bog down. This has happened to me three times, all on the first outing after filling it with gas. I fill the gas from cans not at a marine dock since there is not one near me.
I took it in to the shop but of course, they couldn't get it to act up.
Also, each time it has happened I have heard a very brief beep like the alarm but it only lasts a nano-second...water pump is working and oil level is full.
the fuel filter appears to be OK....maybe it is coincidence but I believe it has to be something to do with the fuel since it seems to occur right after filling..although this weekend I filled it with gas on Saturday and didn't take it out until Sunday when this same trouble appeared. Monday she ran great!
any ideas?
