while in a dr's office this morning i picked up a boating magazine. didn't even look or remember the name of it and started thumbing through it killing time and came across an article about a new company that has started making outboard motors that run on propane. this may be old news to all of you but having led a sheltered life it's the first time i've ever heard of it. they have been making yard machines for a while. the article said they plan to make outboards up to 175 hp. seemed a little high to me but said it compared to regular outboard prices. it will also run with a bigger tank with a hose or with the small cylinders you buy at walmart.

I used to deliver propane, most of our bobtails ran on it. Burns verrrry clean. Took one of the trucks to get emissions checked, they just slapped the sticker on the windshield. Was at a place that builds lp trucks, they got in an old one, rust bucket. Tore the engine down, spotless. A lot of countries run lp/ or natural gas in cars, trucks, busses. USA is way behind the curve.

Propane for engines is what many in the business call "The New Diesel Fuel" Many large haul cross country truck firms are switching to propane engines. Flying J truck stops are installing propane or LNG refueling pumps. Also many garbage truck fleets, school bus companies and the like are switching engines over to LNG. Why one company is now building a LNG engine to replace diesel locomotive engines, they are also in the process of design& build a tender car (like the old coal tender cars) to fuel the new LNG engines. Several of these truck firms are reporting 10 to 20% saving on fuel costs. Doesn't take long to recoup saving on a new truck at 20% fuel reduction costs every year not counting the fact that the new engines will have at least a double lifetime an more. Look up a company called westport innovations- WPRT

i have a friend, yes i have one friend, here that owns the local l.p. gas place. i talked to him a while back about him changing his delivery trucks over to propane motors. i'm sure it would take a while to re-coup the cost but i think in the long run he would come out ahead. and yes, i can find non-ethanol gas. i just posted this because i've led a sheltered life and never heard of propane outboard motors. back in the 60's some farmers had propane pickups. they didn't have quite the power of regular gas engine pickups but like jax, above, said their motors lasted a lot longer. and propane tractors of old just keep on going.

running engins on propain has ben around for a long time . my unckle had a irrigation pump he bought in the 50`s a flat head chrysler that ran on propain .any 4 cykle engin can be converted to propain.

yes they have papa. lots of old tractors from the past were propane. i even had a propane cotton picker. it will be interesting to see if or how long it takes propane outboard motors to catch on, if they do. the article said they already are trying one, i believe, 75 hp. and another article said he planned on building them up to 175 hp. the smaller engines can run off your bbq propane tank which won't be much differnce in weight than a 6 gal gas tank full. probably even lighter.

What are the downsides to going with propane? I liked the idea of cleaner burning but would worry about lack of power and compartment size to handle tanks for bigger boats.

bronson, go to their website and ask that question. LEHR - Environmentally Friendly Technology (http://www.golehr.com). they might answer it. supposedly they are running a 75 hp now.

I used to work on natural gas engines in the oilfield down here. Up to 2500 hp. But they were huge. They are a lot cleaner than gas or Diesel engines. The oil doesn't get as dirty and lasts longer. Just as easy to work on as most 4 cycle engines are.
