Why It Matters

Ethanol fuels absorb moisture, break down faster, and leave behind deposits that clog injectors and carburetors. Over time, this can lead to difficult starts, reduced performance, and costly maintenance. Using this fuel stabilizer prevents phase separation and keeps your gas clean—so your engine fires up reliably when it’s time to get back on the water.

It’s peace of mind in a bottle—and one of the smartest additions to your maintenance routine.
