Propane Outboards?

Has anyone actually seen one in operation? I noticed a thread by bljones about converting a gas outboard to propane, but this is commercially available.

Just curious, I'm not an early adopter for this kind of thing. Rather wait for 2nd or 3rd generation to see if it's a viable option. Couldn't find specs for the burn rate yet.

eh. the above motors are outboard and the fuel tanks are out in the open and in a open boat. Not very much more dangerous then someone smoking while running the engine.

Propane in closed spaces is at least as dangerous as gasoline. ANY fuel that's highly volatile and or heavier then air, is the danger with engine rooms and compartments and bilges.

Well, that's interesting. Apparent upside of propane would seem to be the elimination of clogged up fuel jets, from old, gummy fuel. Here in Michigan, or course we're seasonal with our outboard use, so that could be an advantage.

Getting additional fuel would be a pain in the neck, unless a reasonably sized fuel container goes a looooooong way.

I use a small outboard with a internal tank...I can "slosh" the motor and take a look into the tank to see how much fuel that I have...would you have to carry one of those heavy as bag of bowling balls and just as handy tanks with you? or may be use those canisters that you use on your camp stove...just screw one on to the motor. I worked in a warehouse with a propane powered fork lift tools were needed to change the tank and of course they would walk off and I already can hear the sound of a adjustable wrench splashing into the drink...yes it was clean running but the electric fork lift was cleaner and quieter and when done with that we would just plug it in....

Go ahead and be a purist, but I think charcoal powered outboards suck!

So if you cook drift wood in a burner in the middle of the dingy and pipe the wood gas to the outboard (4 stroke) your fuel bill would be drastically reduced. A 5 gallon pail of sawdust could troll you all day .

More details from Cruising World and new brochures/specs on the Lehr website (~37 pounds, 72cc). Some mixed reviews out there on their other products, but it's good to see an enterprenuer out there willing to take risks.

Go Green With Lehr | Cruising World

"The new quiet-running four-stoke Lehr propane-powered outboards created a real buzz in Miami, taking Green Product honors from West Marine and recognition from the judges for the National Marine Manufacturer’s Innovation Awards. Lehr moved on from its lawn-and-garden propane product line by introducing two small outboards at the show, a 2.5- and a 5-horsepower model that can run off either camping gas canisters or larger propane tanks similar to what one would use to power, say, a barbecue. The 2.5-horsepower short-shaft model will run wide open (4,000 rpm) for about an hour on a camping gas canister, which is inserted into an opening in the engine’s cover. Throttle back to 3,000 rpm and you’ll more than double the run time. A 20-pound propane bottle will power the engine for about 50 hours, or roughly the same run time as a conventional outboard and 5-gallon tank. The more powerful model comes in both long- and short-shaft configurations. Notes Lehr founder and CEO, Capt. Bernardo Herzer, the engines will cost you about half as much to run as a gasoline-powered outboard because propane is less expensive than gas. Better yet, CO2 and carbon monoxide emissions are greatly reduced. The first shipment of engines from the Los Angeles-based company is on its way to dealers. Average price for the 2.5-horsepower model will be just under $1,000; expect to find the 5-horsepower engine for about $1,600. The company expects to develop larger engines, too; look for one in the 10-horsepower range later this year. Lehr, www.golehr.com"

Easy winterization, no stabil in the tank, better throttle response, and less weight for the same range...there's a lot of potential here.
Pwer might be down slightly, but probably still better than a 2 stroke that is running on dirty plugs because the mix has been eyeballed for 10 years.

It's 5 o'clock somewhere:
