CONTINUOUSWAVE

I have an update with my Mercury 115EFI. October 2022 I took out the boat for diagnostic runs. [The Mercury 115 EFI engine] stalled out at full throttle [when running from] the boat’s fuel tank.

Thanks again for the answers. I've had 4 primer bulbs, oriented essentially horizontally (maybe a little upward toward the engine) on the back of the boat, which is a 2006 Crestiner Canadian 1850. I've had the anti-siphon valve checked 3 different times and the mechanics have been reluctant to just ...

The claim is that the FSM gets fouled up eventually trying to pull gasoline through the primer bulb an...

Thanks everyone for the help. The Mercury [mechanic] guy thinks [the cause of all these problems is] probably the fuel tank. I will get an auxiliary tank. Once the engine stalls, I will connect the engine to the auxiliary fuel tank. I will see if that change prevents a relapse. If [a different fuel ...

I have an intermittent but annoyingly recurrent problem with my 2006 Mercury 115-HP FOURSTROKE EFI motor that has escaped diagnosis and which no one can seem to fix. This 2006 engine is from an apparently short lived-joint venture with Yamaha, and has less than 650 total hours. Beginning about three...
