The first propane-powered outboard engines, LEHR 2.5hp 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.

Introduction to LEHR technology video

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. Convenient Twist ’n Go fueling on 2.5hp model. Simply twist in a standard 16.4oz. propane canister and start your engine—no messy mixing or gasoline storage required. Or connect to a standard LPG tank with the provided 4' hose assembly for longer run times. Includes 4' propane fuel hose for remote tank.

Suggested Tank Options:

2.6 gallon composite tank (11lb.)

      We use the Lehr 2.5 on our 18ft Trimaran sailboat and have been perfectly satisfied with it's performance. We use the 1lb Propane bottles which last about an hour at full throttle. Changing the bottles is a snap and can be done in a few seconds. We average 5-6 knots at full throttle.

      I purchased this motor to go on an 8' molded plastic pontoon bass boat rated for 3hp. It was easy to set up and is easy to operate but does not give me much more power or speed than the 60lb thrust trolling motor I already have. For 1k+ dollar product, I expected a much higher thrust output than what I am getting. If I had to do it over again I would get the 5hp motor even though it exceeds the rating on my boat. Also, the throttle handle has a convenient throttle trim nut, but does not extend out, so you have to be relatively close to the motor to operate. In a small boat like mine, that puts both my weight and the weight of the motor on one end of center and does not lead to ideal weight distribution or float characteristics.

        Comments about Propane powered Outboard Marine Engine, 2.5HP, Short Shaft:

        I've had the Lehr 2.5 since 2013, I was one of the early adopters. I use it as auxiliary power on a homebuilt Woods Strike 18 trimaran sailboat in lakes around North Texas. The motor starts and runs great and I havent had an issue with it yet. The propane canisters are clean and cheap as well.

        Comments about Propane powered Outboard Marine Engine, 2.5HP, Short Shaft:

        I used this on a flat back canoe and small John boat. It ran Like an old two stroke at first but it did run. It could take anywhere from two to two hundred pulls to get it to start. I was really excited about using propane at first but problems started soon. Many small parts began to rust and break. Then it just wouldn't start at all. I took it to the place Lehr said to take it to and the didn't want to work on it. So they found someone else. From there it went into the shop and out over and over. It spent more time in the shop than out over the next year. Finally Lehr gave me a replacement. As soon as I opened the box I noticed a screw that was in the first motor was missing from the second. Then it wouldn't start. Finally it started after trying again and again. I took the new motor out and while passing some kayaks I tried to slow down. But the outbourd decided it was going to open up full throttle. Same thing happened while trying to dock. Lehr said I could take it to the shop. I laughed at him and decided to buy a gas motor.

        Comments about Propane powered Outboard Marine Engine, 2.5HP, Short Shaft:

        Early spring 2014 I was assured by my favorite marine supply retail that the previous issues reported the past year in the reviews were fixed and he was high on it. So I took his recommendation and bought it. took down to the lake and on small sailboat and hard to start but ran fine to go out but would not start again when ready to power back, spent 45 minutes rocking around in a day sailor and had to sail on to the beach...the store replaced the motor, second motor aslo hard to start, the kill switch mechanism broke off easily on the second outing, put it on my little aluminum boat to troll and on low speed the propane fumes coming back were to much to take,....takes several pulls to start all the time,...not impressed at all with the power. Now the retailer will not take it back,...stuck with it.

        Comments about Propane powered Outboard Marine Engine, 2.5HP, Short Shaft:

        Either I have a lemon, or all of the claims of the ease of starting this motor are completely false. It always takes six or more pulls to start, three minimum when it's warm. Twice now the motor wouldn't start at all and left me stranded. When it runs, it's pretty sluggish and feels underpowered, but it's way unreliable. I've had my 2.5hp Lehr for a year now and have decided it is good for little more than a boat anchor.

        I contacted service and initially the rep was helpful and gave me a boat dealer to take it to for service. I called the boat dealer but no one answered. A short while later they called me back (I didn't leave a message, so I thought that was a great sign that they wanted some work to do) but when I told the guy I had a Lehr that needed service he suddenly couldn't help me until after Thanksgiving, said they were too busy. What? I wrote back to Lehr to see if there was another repair shop and I haven't heard anything back.

        My gut feeling is that these motors, while cool in concept, are just not ready for primetime. It's hard to start and very sluggish. The last time it died a couple weeks ago I was in the Keys for vacation. It ran great one day then two days later when I went to use it again it simply would not start. I've tried repeatedly since then and it's simply dead. I was so frustrated I went out and bought a 2.5hp Mercury four-stroke. Now it starts on the first pull every time and easily has twice the power of the Lehr. Yes, I will miss the convenience of the propane canisters, but hopefully I have a reliable motor now.

        Comments about Propane powered Outboard Marine Engine, 2.5HP, Short Shaft:

        I purchased this motor as an auxiliary for my sailboat but from the day I bought it, it has been nothing but trouble. I've had it less than a year and currently it will not start. I would like to have it serviced but there are no local repair centers that work on Lehr motors. I debated between this motor and the Honda 2.3hp. I went with the Lehr because of the promise of trouble free operation and the novelty propane fuel. Now I truly regret my decision. My friends that purchased Hondas say they are very reliable and are easily serviced. So now I am stuck with a very expensive motor that will not run and no way to fix it.

        Comments about Propane powered Outboard Marine Engine, 2.5HP, Short Shaft:

        Nice idea, but implementation needs work. When working properly, starts on the first or second pull, no gasoline fumes, self contained unit with small propane cylinders. Worked great for the first year. In the second year, I needed to have new seals, head gasket, multiple fuel line leaks, and complete failure to start. Problems have been covered under warranty, but service is not always easy to find.

        Comments about Propane powered Outboard Marine Engine, 2.5HP, Short Shaft:

        I've had this motor for a year now and have used it hard. I use it on a home built, wooden skiff and a square stern canoe. Propane beats gas in so many ways. Mine works like an anvil. People complain about the strangest things...kill switch key tricky to install? it's a standard kill switch configuration. Someone found the tiller handle length inconvenient for his particular set up...again, it's a standard length tiller handle. These are things standard to all outboards. I'll agree the motor cover fit is a tad imperfect. But I wouldn't let that frustrate me unless there were negative consequences that resulted...and there have been none for me. It's never come off or loosened. I'm still catching fish. I do appreciate that some folks could have wound up with lemons. I have spent more quality time fishing than I used to because of the convenience, performance, and quality of this motor. This is the future of marine outboards.

        First 18 months with a Lehr 2.5 hp motor

        By AJ Rogers

        from Portland, OR

        Pros

        • clean
        • No Gasoline Smell

        Cons

        • Availability Of Service

        Best Uses

        • Dinghy Motor

        Comments about Propane powered Outboard Marine Engine, 2.5HP, Short Shaft:

        I purchased a Lehr 2.5 hp outboard in Feburary of 2013 to replace a Honda 5 hp outboard on my inflatable dinghy. I was tired of smelling gasoline fumes and the Honda was larger than I needed for our rollup dinghy. Initially, I was quite enthusiastic about the Lehr motor. It solved the gasoline fumes problem, always started on the first or second pull and was quite reliable. I really like the idea of eliminating one of the fuels from my boat, and I already use the propane camping cylinders for my barbeque grill. I found that I had to replace the propane cylinders more than I had expected, but if I ran the motor at a low speed, I could get about two hours of operation from one camping cylinder.

        There were minor issues that tempered my enthusiasm a bit. First, Lehr recommends "disconnecting the fuel" after every use. It was not clear to me if that meant removing the small cylinders or (if used) disconnecting a larger external tank. I never used an external tank and left the cylinder in place until empty, partly because I found switching cylinders to be painful to my fingers due to the short hose in the engine and the limited clearance it affords to hold the threaded gas fitting while installing a new cylinder.

        Another issue (perhaps not unique to Lehr,) is that in salt water, they recommend running fresh water through the engine after every use. This is easier said than done. There is no fitting to attach a garden hose or other water source to introduce cooling water to the engine. And the usual motor flushing accessories won't seal around the water inlet due to protective fins and the small size of the shaft housing. So that left me having to use several gallons of water in a plastic trash can held in place by a strap while I ran the engine attached to the rail of my sailboat. I don't know what the requirements for other outboards is, but I ran my Honda for entire seasons without rinsing until the end of the season and never had any problems.

        All in all, I was very happy with the Lehr outboard for the first season of use. I used it several times per week for the entire 4 months I lived on our sailboat in the Pacific Northwest, and apart from the minor issues above, had no complaints. THIS SEASON, however, is a completely different story,

        After being properly put away for storage in the winter, I first attempted to fire up the Lehr on a trip from Washington to Barkely Sound on Vancouver Island. The instant I attached a gas cylinder, I heard and smelled propane shooting out from inside the engine in the vicinity of the fitting for the external tank hose. At the time, I was far from any authorized service location, but desperate to get it running, so I contacted Lehr and got a timely response to my inquiry about repairing the leak with O rings purchased from a hardware store. I was able to replace the seals of the internal fuel line with O rings and new gas compatible Teflon tape, and there were no more leaks. The motor ran fine for about a week.

        Then, the motor started becoming difficult to start and was not running well. Finally, when it would not start at all, I tried replacing the spark plug. I was able to start it and it ran badly for about an hour. At the point it died again, and I noticed that the oil had turned white, looking at the oil level inspection glass. At this point, I contacted Lehr again and began the (arduous) process of finding somebody authorized to work on it. There are plenty of stores which sell the Lehr motors, but apparently far fewer that actually service them. Finally, I was able to get the motor to Harbour Chandlers in Nanaimo and after a brief diagnosis (mainly to be sure I hadn't dropped it in the water, I suspect,) they ordered new seals and a head gasket. Lehr was able to get them the parts in a timely fashion, only three days including customs, as the parts were shipped from California. The mechanic replaced all relevant seals and the head gasket and (four weeks after the problem arose) I now have a working motor, which once again starts on the first or second pull and seems to run just fine. There was no cost to me, apart from the moorage fees, taxis and time lost on our trip. The engine comes with a three year parts and labor warranty, and they seem to honor that without a problem.

        I understand that a Chinese company (Parsun) manufactures this motor for Lehr, and also very similar motors (except for the fuel system) for Yamaha, Tohatsu and other companies. That gives me some confidence that the reliability of everything except the fuel system should be similar to other small outboards on the market, despite my unfortunate experience. I am keeping my fingers crossed that this is the last problem I have with this motor and that I get a few good seasons of use from it. My serial number ends in 00090, so I think I have a very early motor. The manufacturing date is shown inside the engine as May 2012, even though I bought it in February 2013. Hopefully, the new motors are less prone to problems.

        right out of the box the pull handle did not line up. Took off the cover to see cracked/broken plastic cover on the cord recoil system. Kill switch has a rubber tip that makes attaching the "key" tricky.

          Comments about Propane powered Outboard Marine Engine, 2.5HP, Short Shaft:

          I've had the kids using our AB 9'6" RIB which weighs around 140lbs or so all weekend. A 9 year old can start it with one pull when warm. It has an alarm that went off when the propane tank needed to be changed. Small engines are such that outboard mechanics are recommending you replace your carb every year. With ethanol, you absolutely can't rely on an outboard to get you anywhere. Now with the propane motor, no more carb cleaning which doesn't work, flooding it when you give it too many pulls, water in the gas, dirt in the gas, anything in the gas. It simply works. And you can lift it like a small suitcase with one arm and carry it back to the dingy rack and store it. The kids were using it full throttle all the time, and I think it probably last about an hour. They had a blast. Either way, now I know I can finally rely on an outboard again. I've owned 5 outboards in the past and spent maybe 3,000 miles motoring with them over the last 20 years. I'm happy to be done with gas.
