I’ve heard that side as well. And keeping your tank full does help. It’s the shelf life of e10 gas. If you’re running your boat all the time or monthly. And you don't know how fresh it is when you buy it. If you keep the boat on the water its in a humid environment . When e10 starts to go bad it goes through phase separation. There’s where the Star Tron comes in. It prevents phase separation for a much longer period of time. And a fuel water separator is the way to go as well. The little rig I have now uses a portable fuel tank which when not is use sits in my shop 1/2 full or less sometimes. I don’t always keep it full because I premix for the 2 stroke. I have a water separator and haven’t had any problems. Fallow the directions for how many hours to change it. Maybe less in your case. If you can get one with the clear bottom and you can see the water accumulation and can stop a problem before it happens. Look up the info on Star Tron website.
