Class action lawsuit ( mercruiser) vapor-lock issues.

Nailit, so teeing both return lines together to a single hose didn't cause any issues. I was afraid there would be some type of fighting between motors doing so. That would make it so much easier

My 502 mpi w/VST vapor locked several times a few years back and it was mainly ethanol and winter fuel mix. Filled the boat up at the local gas station before putting it away for the winter. Managed to get most of the gas burned and filled back up with pure gas. I only use non-ethanol fuel now and so far no issues. I do make sure after running on hot days to do a bit of idling to cool the engine down, but so far so good.

I think that's a key point, idle down after a run. I've always done that, idled around 1100 for a minute or two before shutting her down. It's enough to move the gauge south and has to help getting cooler water ingested before the heat soak.
I've never run anything but E10 or whatever they're pumping at the quick stop. No ethanol free stations around here.

I was told that when I bought the boat, but twice last summer after doing so no start. Once I was idling into a no wake bay, long and narrow it crapped out. 15 minutes later starts right up and golden. There is no rhyme or reason to when it occures. The only difference I could see was it was at a lake 6 or 7 hundred feet higher in elevation than I normally boat at.

Twice since I've owned this boat I had to depress the fuel pressure check valve (looks like a tire valve) on the front of the fuel rail to release the vapor. Actually, I'm amazed how much vapor comes out before fuel. Afterwords, starts right up and keeps running. Kind of embarrassing though. Learned to idle with hatch open slightly like others have mentioned since.
Unfortunately, no ethanol free gas around here.

In stead of raising the hatch, just run the blower.
So far as non-ethanol gas, here in KY I'm starting to see it at the corner station in Premium. The inland lakes I boat in many, but not all have non-ethanol gas at the marinas for mid and premium grades. Locals know which marinas have it. I only need 87 octane but will run the mid grade do to ethanol.
