Went skiing the other day and after 4 runs down the lake, the engine gasped and died when accelerating. We were able to limp back to the dock at idle, but any time giving the slightest bit of throttle, the engine would gasp and die.
Background:
About 400 hours on the boat.
Last year replaced the low pressure pump, kill switch, filter, and anti-siphon valve. Eventually found the fuel relay to be the problem.
The boat was just randomly cutting out like a kill switch issue. Later learned that the relay goes out gradually and acts like this a lot of times.
Current:
While replacing the filter after the problem described above, (everyone thought is sounded like a plugged filter) the wire seal on top of the FCC leaked, so I now have a new FCC (it is sold as a complete unit with high pressure pump) and it is still doing the same in the driveway. I was able to test the fuel rail pressure and observe that it was up around 40 and as I gave it some rpms, the pressure dropped to 0, then was just surging at idle, like it is getting shots of gas, but didn't idle smooth after it gasped at rpm. I say gasped, because that is the sound I am hearing from the engine.
My thought is the year-old low pressure pump is bad or the fuel relay is acting up again. This is different than the problem I had last year, when the boat would run fine, then just die.
Any thoughts or prior experience with something like this?
Thank you.
