I recently purchased a boat with a 250 sho and I have been running Yamaha Ringfree but I know this is not a ethanol buster. Is it recommended that you run Ringfree and an ethanol buster such as Biobor? Also is there a certain octane you should run on the gas?This is my first four stroke and in the past I always ran Biobor on my pro xs. Thanks
I run this in the recommended dose plus I put about a 1/4 of the dose of biobor in too. Might be too much fuel treatment, but I've not had any issues. I also have a fuel water separator filter too. Newer model Skeeter probably came from the factory with this:

My new Merc 250XS has a fuel filter/water separator as big as the after market in-line types I have had on other boats. Its under the cowling. I assume this is adequate. The SHO not have a built-in separator?
You should have one mine was mounted directly in front of engine in the compartment you couldnt see it unless you stuck your head down in there to look you couldnt see it standing on the ground looking.
