You only need to add something to the fuel in case the fuel is planned to be stored, to lengthen it's shelf life. In this case though, I prefer to siphon the fuel from the tank as opposed to adding stabilizer, if possible. Some vessels have quite large tanks though.
Use good quality, fresh fuel as per your owners manual instructions, it's especially important in the case of constant duty marine engines.

I would try to stay away from ethanol fuel. Two things. It goes bad faster as it dries out - It lacquers up plugging up the system . Two, it allows water molicues to be absorbed into the fuel - allowing the fuel system to freeze up below 30°F/0°c.
It's okay if you are going to burn through it during a weekend using the 92 Octane.
Try to leave little in the fuel tank during winter storage and add Fuel Stablizer. Then, in the spring/summer give it fresh fuel.

I here you about ethanol I went to a website that lists gas stations that sell real gas the problem is there just isn't any gas stations around me that sell real gas no ethanol and 92 to 94 octane . I found 1 that is 60 Miles away they sell real gas no ethanol but it's only 89 octane

Then the best thing to do is burn through it. Add Fuel Stablizer during the season. Then leave little as possible during storage and add Stablizer for long storage.

To protect the pollution control devices and other things in the engines , the government today requires all fuels sold to have cleaners in them . When you think of the fact that your sending as much a whopping 20 gal / hr through but just 3 injectors of these cleaners through your fuel system , a pwc one would think would have less of a problem then the typical car

Sorry, I just realized this is a fuel injected ski. In that case it's best to keep the fuel tank full and stabilizer in the fuel during off season storage.
non-ethanol has a much longer shelf life than ethanol does, including when stabilizer is added for off-season storage. This is why marinas sell non-ethanol when/where they're allowed.

One might think so but cars are driven daily thus they rarely have stale fuel sitting around in the tanks, dissociating, absorbing moisture, and suspended solids precipitating out.
It's pretty common to find tons of junk in boat fuel tanks if they sit around unused. If that tank has an electric fuel pump inside, allowing it to sit empty allows moisture to attack the pump and exposure to air allows the fuel remnants inside the pump to turn to gum as it dries out, the electric fuel pump begins to take on the look of a russet potato sporting an afro. If it doesn't fail as a result it's shedding junk that gets caught in your injectors.
So yeah, try to keep your fuel fresh. Stabilizer does extend the shelf life considerably. Marine engines are constant duty, this mean there are no coasting periods like in a car rolling up to a traffic light and only turns maybe a few thousand RPM at most and as you point out burning 20 gallons/hr is a great way to make tons of heat so under these conditions it doesn't take long to damage an engine if the fuel isn't burning correctly.
Fresh fuel is so important!
