TSD Diesel Inboard vs Gasoline Outboard

Diesel has a high flash point, is not easy to burn, and is safer.


Fuel types more compliant with government requirements and easier to buy.


Higher fuel efficiency and economy, durability.


The initial purchase cost is high, but the maintenance cycle is long and the user operating cost is low.


Greener and emits less CO2 than gasoline


Gasoline has a lower flash point and has a higher chance of an accidental explosion.


More and more government directives require that government ships in the fields of defense, navy, etc., transition from gasoline engines to diesel engines.


Fuel consumption of the same horsepower is about 40% higher than that of diesel outboards.


Low initial acquisition cost and high long-term operating cost.


More carbon dioxide and pollutants.
