Understanding the effect of ethanol on boat engines

When discussing fuel options for boat engines, it’s important to understand the role that ethanol can play. A common component in most types of gasoline, ethanol is a kind of alcohol that is derived from plant materials. It’s renowned for its effectiveness in reducing greenhouse gas emissions, which is why it’s frequently added to gasoline. However, while it may play a critical role in combatting global warming, it can cause issues when it comes to boat engines.

The chemical properties of ethanol

Ethanol is a clear and colorless liquid that can absorb water. It is polar, meaning it can easily mix with water, but it doesn’t mix so well with materials that are nonpolar. This capacity to bind with water is where the trouble starts when it’s introduced to boat engines due to the tendency for water to accumulate in boats.

Why ethanol is problematic for boat engines

Due to its hygroscopic nature, ethanol can attract moisture from the environment, leading to an accumulated water-ethanol mixture inside your fuel tank. This can subsequently lead to phase separation, where water and fuel become distinct layers that can interfere with the overall functioning of your engine. Additionally, ethanol can act as a solvent that can loosen dirt, debris, and rust in the tank and fuel system, causing clogs and even engine failure.

Signs of ethanol damage in boat engines

Ethanol damage in boat engines can manifest in numerous ways, which include erratic engine performance, poor acceleration, and unexpected engine shutdown. The presence of excessive water or sediment in the boat’s fuel filter can also hint towards ethanol damage.
