Fuel utilized in watercraft engines and that dispensed at typical filling stations are often perceived as interchangeable. However, fundamental distinctions exist regarding composition and additives. Fuel designed for maritime applications typically omits ethanol or contains it in very low concentrations, while standard automotive fuel frequently incorporates a significant ethanol blend.
This divergence is crucial because ethanol can be detrimental to marine engines. Ethanol attracts water, potentially leading to phase separation, where water and ethanol separate from the gasoline, creating a corrosive mixture. Such a mixture can damage fuel system components and compromise engine performance. Historically, marine engine failures attributable to ethanol-related issues have highlighted the significance of using the appropriate fuel type.
