Johnny.....I operate on a 5 month use and 7 month storage schedule.
Manual says to treat gas and run for a bit and then fog
cylinders.....which is exactly what the dealer does at the end of the
season. And yes, this is a 4 stroke motor and no one confuses 2 stroke oil with 4 stroke.
In the spring I burn off the previous years treated gas and then change
my water filter. Motor starts up right away and might smoke for a
couple of minutes...but works well after warming up.

Why would you keep gas over the winter? When you cover the boat for
winter, pour the gas in the RAV4 from all the gas cans. Start new in the
spring. I have had problems with my boat and old gas after an extended
layup. But my tank is harder to empty. 70 gallons.
