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' hose assembly. Remote tanks are sold separately.

    Comments about Propane powered Outboard Marine Engine, 9.9HP, Short Shaft:

    I mounted the motor, filled the oil to the proper level (not overfull), and hooked up water and propane.
    40 pulls later, no sign of turning over. I may have pushed the throttle too far (up to 1/3), so disconnected the propane and let it rest overnight. Next morning, I was able to start it after 40-ish pulls, in the driveway. It ran fine, once started.
    Got it in the water and it started after 30-ish pulls, then ran it for 15 minutes and shut it off.
    Now, it was REALLY tough to start. After 60 or 70 pulls, I was ready to give up. My 10-year old started praying and low and behold, the thing started.
    Anyway, I just tried to start it again in the driveway and no luck, after 60 or 70 pulls, at different, low throttle settings.
    I'm disappointed because I was hoping that my 14 year old could use it, but no way he's going to get it started.
    I'm hoping for some help or a replacement from the Seattle store right now.
