Oil and Gas mixing

[coachdaddy7]

Running a 1999 Yamaha 40 HP with seperate gas and oil mix tank. Boat sitting 2 months for trailer repair. Will the oil and gas seperate in the tank and need remixing? Thanks for replies, oil and gas are in one 6 gal. tank with proper amount of marine Sta-Bil. Worried that when I run it, the oil and gas may have seperated.

not sure how you can have a separate gas and oil mix tanks.
maybe an oil tank and separate gas tank.

If this is a pre mix motor it should be something like a C40TLRX as mine is, but yours may be something different.
Always good to post what you motor model # is when asking questions about it.

But once mixed oil and gas does not separate back out.

Even mixed fuel can go bad from just sitting if not stored properly for 2 months

Pretty sure that's what he meant, a fuel tank and oil reserve tank. I think he was asking if the fuel/oil mix in the fuel tank will separate.

Sounds like pre-mix in ONE tank to me....
