How To Tell If You Have Bad Gas In Your Boat?
Poor maintenance is often behind the safety issues regarding any vehicle. This can also cause your boat’s gas to go bad.
Before you take any step, it is essential to confirm that the gas is bad. The following symptoms may help you determine if your boat has bad gas.
Symptom 1: Change in Smell

If you leave the same gasoline in your boat for a long time, it can get old and change its smell. You would get a pungent varnish-like smell which is not so pleasant.
Symptom 2: Change in Color
Another big symptom will be the change in color. Usually, the best-grade gasoline should have a transparent color. If you find the gas in your boat a bit darker, the gas has gone bad.
It happens because of oxidation. The transparent color starts to change and slowly turns a bit yellowish. If you notice a color change in the gas, you may need to replace it.
