Please do not move this thread. I have a Merc Stern Drive with a 35 Gallon Gas Tank and want to hear what like owners think. I know what Merc recommends but Boat U.S. is also highly respected and I would like to hear some dialog.
Boat U.S. recently came out with a recommendation that boats in winter storage should have their tanks filled to 95%. According to them it helps to prevent phase separation of the Ethanol Gas. Once that happens they also say a water separator or treatment doesn't help.
Merc and my dealer say to leave the tank close to empty for winter and fill up in the Spring. Boat U.S. says that promotes condensation and phase separation. What do you think is the best way?
