Maybe this will help. I have a 05 197 with the MCX 350 multiport fuel injection. I have had the 3 different issues with the fuel pump.The first time it was the relay located on the back of the motor, there are 3 of them as i remember, i would replace all 3. The 2nd time i had a problem it was the fuel pump. I removed the canister out of the fuel tank and took the canister( fuel pump assembly) apart, removed the fuel pump from inside and bought one at the auto parts store down the road. The part number I found in the mastercraft team talk. Its a fuel pump for an old corvette, that's what the parts guy told me. The mastercraft dealer told me not to run the gas level below 1/4 because it makes the fuel pump work harder. I found out why. There is a float valve at the bottom of the fuel pump that stays closed so that the fuel is drawn from above until the fuel level is around 1/4 and then it starts to open and pulls the gas through the fuel filter just below it. During the transition I think the pump runs a little dry or has to work harder. I figured this out after the 3nd fuel pump. I removed the float valve about 500hrs ago and it has been perfect. The 3nd issue was the plug connection to the fuel pump canister on the top of the gas tank. It gets corroded and looses connection. I figured this out by moving the plug around and while putting a little pressure on it had my son start the boat , It would run until I let go of the plug. I had to replace the plug going to the canister. Good luck.
