This engine has a host of sensors that control virtually ever aspect of it's operation. I have the manual for mine and in the trouble shooting section first thing it always says "Did you run a diagnostic scan for codes" I am in the process of finding a dealer qualified to work on mine. I 'm begining to except the fact that I can't fix this one myself.

electric fuel pumps are designed to push fuel not suck! with it being mounted @ the transom that's a long distance for it to suck fuel then pressurize it for the 50psi fuel pressure that the engine probably needs. it could run @ 45 psi, like griff said get the rite fuel pump and mount it as close to the tank as possible and as low as possible so the pump don't have to work as hard to maintain the fuel pressure needed..i would go with a aeromotive,make sure you put a filter in front of the fuel pump,you don't want to jam it up if theirs crud in the fuel tank..

Aeromotive recommends putting the pump as close to the gas tank as possible. Do you have access to the gas thank? If you're hell-bent on running the elec. pump you might want to move it to the forward most position in the engine compartment, as low as possible, and mount it before the mech. pump.

That sounds weird... What size line are running from the mech pump to the elec. pump? It sounds like you might be starving the electric pump for VOLUME of fuel. That big line going into the elec. pump is needed to supply the pump with enough fuel.

Maybe its just my experience with Aeromotive pumps and the volume of gas that they need (and big pick up tubes) that skew my thought process on this...
