Overview Mercury 5hp Propane Outboard 5MH LPG
The Mercury 5hp Propane Outboard 5MH LPG offers a smarter, cleaner way to power your boat. By running on propane fuel, this outboard removes the need to transport or store gasoline while delivering true 5hp output from a robust 123cc four-stroke engine.
Designed for convenience and reliability, the 5MH LPG is ideal for aluminum tiller boats, inflatables, jon boats, utility craft, and small sailboats that benefit from simple, hassle-free operation.
Features and Performance
At the heart of the 5MH LPG is a single-cylinder 123cc four-stroke engine tuned to deliver consistent power across a 5,000–6,000 RPM range. The propane mixer fuel system provides clean combustion, reduced odor, and reliable starting without carburetor fouling common to gasoline engines.
A 3-blade aluminum propeller (7.7” x 8.0”) delivers efficient thrust, while tiller throttle control offers precise low-speed maneuvering. Manual starting keeps the system simple and dependable, and the integrated carry handle makes transport easy.
