My motor is 2016 4.3 MPI.
I experienced my first issue with my boat. Had the boat at the lake over the weekend and one time out it started fine, idled away from the dock fine. Stopped the motor to load kids on the tube went and restarted motor, motor restarted fine. Put it in gear and put the throttle down and NOTHING, it just kept idling. Put it in and out of gear a couple of times by this time I could tell the idle was rough. Restarted the motor, no change. At this point I turned us around to try to limp the 100 yds back to the dock. During this time the idle became progressively rougher , sputtered some and even died once, but it would restart. Made it back to the dock and started investigation.
I have VVM so I grabbed my phone and synced it up. Popped the sunpad checked the motor, oil, visual checks, etc. Everything was in order, no codes were thrown and I never got any alarms. Restarted the motor at the dock and put it in neutral and engine revved up fine this time. I proceeded to go for a quick run around and all was normal. We ran the boat the rest of the weekend without issue, pulling loads of kids around on the tube, etc. I probably put ~2-3 hours more on the motor since the initial problem.
So did I experience vapor lock? Or is something else going on?
It was warm 90-95F this weekend. The time that this occurred it probably had been sitting after running hard for maybe 1-2 hours heat soaking. When I started the weekend I filled up with gas at a Sonoco and put ~11 gallons of 93 octane to fill the tank. Unfortunately I couldn't fine Ethanol free which is what I try to run exclusively.
The boat has run fine thus far and I have never experienced this issue. I just changed the fuel filter at the beginning of the season so I don't really suspect it. Boat has been run numerous times after pre-season maintenance.
I lost some confidence in the boat and I am supposed to take it to Florida in less than two weeks. I would love to hear anything that I should check.
