Product Description

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.

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.

      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.

      I love this thing!

      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

      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.

      QC problems?

      By Joe

      from Rhode Island

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

      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.

        Poor quality control

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

            Right out of the box, engine cover was loose and askew and crimping the rubber gasket. Rear latch was already broken off. Kill switch was loose in the throttle handle - several turns required to tighten it. About 1/2 hour into first use, the tiller handle came off and would be in the lake except the throttle cable held it. I can't even see what is supposed to hold it on so I assume that piece did go into the lake and I will have to improvise something. Motor ran fine but if it got the same poor quality control, it won't last long.

                We use this motor on a 10' Sea Eagle that stores in my fifth wheel. This motor I can easily store in the bed of my truck while traveling. The motor ran perfectly each time I've used it. Plenty of power, granted its no speed boat but its dependable, starts easy, and no fumes or fuel storage. Nice...

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

                  I use this to power a J22 sailboat when there's no wind and I need to get home or get out of the bay and find wind! It replaced a 2-cycle 4HP outboard which was cranky, unpredictable, and fussy. What a difference! Comments about top being difficult to replace after you take it off are true, but I can live with that. It ran all summer when I needed it on a little over 1 small canister of propane. I'm putting a retractable motor mount on the boat next year to replace the fixed mount because I wasn't able to tilt the motor out of the water on the fixed mount -- it ran into the transom when tilted. So the prop stayed submerged all summer, which I'd like to avoid. The manual isn't very good, either. I wasn't able to locate all the adjustments because the photos in the manual are too dark and indistinct. Despite the problems, though, I still like the motor and am glad to have it.

                    Big disappointment. Started from 3 to 18 pulls. Cover is really flimsy and hard to get latched. Fuel runs out of tank unless you disconnect after each use. Low power output, would only run about 1500 rpm under load. ???
                    Seems fuel hungry. Book says idle speed is 2000 rpm; seems a little high don't you think.
                    Too bad for this mfg. Hard to be a pioneer when your product flops this badly. I'll probably never try another one.
                    I guess I could have gotten a bad one. Who knows.
