LEHR Propane-Powered Outboard Engine

The first propane-powered outboard engines, LEHR 9.9hp and 15hp motors present an environmentally-friendly and cost-effective alternative to gasoline. Electric Start portable motors with internal starter battery that recharges while the engine is running. Your portable outboard remains portable—no rigging or clutter in your boat!

Overhead-valve four-stroke engines run on 110-octane propane, and are eco-friendly with zero evaporative emissions, because propane, unlike gasoline, is not listed as a marine pollutant by the DOT. Propane is 50-times cleaner than gas, with 96% less carcinogenic compounds, 60-70% less smog-producing hydrocarbons and no Class I or II ozone-depleting chemicals. It’s also domestically produced, reducing our dependency on foreign oil.

LEHR outboards are easy starting with no choke and no priming, reliable with no carburetor gum-up or winterizing, economical because propane costs roughly half as much as gas. 9.9hp and 15hp models connect only to remote tanks and are complete with a 10' hose assembly.
