The LEHR 2.5 HP outboard motor is powered by lean, efficient, eco friendly propane. Simply twist in a standard 16.4 oz. "camping" style propane canister and go!. No choke, no priming, no carburetor gum up. For increased range use a remote 5 gallon "BBQ" style propane tank. LEHR also offers two sizes of lightweight composite auxiliary tanks.

Fuel consumption for the LP2.5S 2.5HP model is .10 gallons of propane per hour at 3000 RPM which translates to a 2.5 hour running time on a 16.4 oz. Camping Bottle of propane. At 4000 RPM the LP2.5S burns .24 gallons of propane per hour for a running time of one hour on the same 16.4 oz Camping Bottle of propane. However, by using the optional remote 20 lb. auxiliary BBQ tank option this can be extended to 20 hours at 4000 RPM and an incredible 50 hours at 3000 RPM. All times are approximate and may vary based on the size and type of boat, wind, current, and other factors.
