2004 Mercruiser 5.0 MPI - SN: 0W011661
Alpha Drive
I put my boat in the water on Saturday and it ran perfect. After a few trips up the lake, I was idling into an area we park and hang out at. I noticed the boat begin to idle and sound rough. It eventually died all together. After that, the boat would start fine, but immediately die shortly after. If I attempted to rev the engine it would die. It was like it was starving for fuel.
The next day, I took the boat and filled it completely full with gas. It took 37 gallons to fill it up, and since it was a 50 gallon tank, that means I had 13 gallons in the tank. I got it home and hooked it to the hose. The boat started fine, started to act like it wanted to run rough, but then started running great. I allowed the boat to idle on the hose all the way up to temp. In total it ran for 30 minutes on the hose and sounded great.
I am left wondering what the issue was. I am putting a new fuel filter on it this week. When I did my seasonal maintenance, my ship only had a sierra fuel filter. This is the first time I've ever used a non-mercury fuel filter. Is my fuel pump failing? I wanted to see if anyone else has had a similar issue.
