LEHR Outboard Motors 9.9hp Propane Powered Outboard Engine, Short Shaft, Manual Start

The first propane-powered outboard engines, LEHR motors present an environmentally-friendly and cost-effective alternative to gasoline.

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′ vapor hose assembly. Remote tanks are sold separately.
