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.

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.

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 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.

Comments about LEHR 2.5hp Propane Powered Outboard Engine, Short Shaft:

Talked my dad into buying the 2.5 because for the dependability promises. After 1 year he has had it to the shop twice. Both times carb issues. Still very hard to start and stalls below 1/2 throttle. Cowling a very poor
fit. Water discharge hard to see. Propane vent at carb hard to get to and improperly Idenified in manual. Manual very vague on many issues. Oil change very difficult. Very embarrassed that I talk my dad into buying this engine.

      Two years in and it's been in the shop now for three weeks. The engine had a propane leak in the fuel line and a cracked carb with another propane leak and the little metal tab that keeps the engine out of the water broke within the first few weeks. It's a hard staring engine when cold needing 3 to 4 pulls. The engine is so load you can't talk to a passenger when going at anything more than idle. It seems like an engine which you probably won't get more than 4 or 5 years of occasional use.

      This review supersedes my first review. Lehr replaced my first outboard which was hard to start with one that starts in two pulls. The outboard performs as I would have hoped.

      Service and delivery comments:

      Yes, very prompt. Thank you Lehr and West Marine for your assistance.

      Verified Reviewer

      Comments about LEHR 2.5hp Propane Powered Outboard Engine, Short Shaft:

      I wanted an easy to use outboard, this one is not. Main complaint it is hard to start, normally it takes 20 to 30 pulls before it starts. It is cold blooded and needs to warm up for 5 minutes even in moderate weather before it can be used. Other complaints are just annoying, such as poor fitting engine cover, when using reverse water squirts in the boat, the propane connecting hose should be longer, the difference between idle and wide open is small, fuel economy not as good as advertised, and it is loud, the propane bleeding tool is a joke. I could live with the annoying things but hard to start is a pain. Wish I had bought another brand.

      Service and delivery comments:

      West marine was great to deal with. They made great effort to get me the product. I wish the product would have been better.

      Good idea - poor execution

      By Jim B

      from Punta Gorda, FL

      Comments about LEHR 2.5hp Propane Powered Outboard Engine, Short Shaft:

      The Lehr 2.5 propane outboard is a good idea. Unfortunately it is made with such cheap part and terrible fit and finish that it is unsuitable for any marine environment. The idle set is touchy with very high revs needed until you put it in gear. The cover does not fit on the engine and while it has not blown off I have never been able to latch down any cover even the display models on the floor of West Marine. After one season the pivot bolt seized and broke. Fortunately I had the engine in hand when the engine mount stayed on my dinghy's transom while the rest of the engine broke off. There is no real way of running fresh water through it after salt water use short of setting up a barrel to run it in, impractical while at anchor. Bottom line -avoid Lehr outboards. The price is too high for the quality of what you get..

              I purchased this motor in 2013 for use on a small 2 person dinghy. It is always difficult to start ... West Marine recently advised that there was a defect in the carb and that Lehr service would tell me how to fix it ... impossible to get a response from Lehr service and the closest repair facility is 65 miles away. Had I to do it over again, I'd have gotten a small Merc ... reliable and dependable. This is simply not worth the money and the time and effort to start it.

              Service and delivery comments:

              Service for this engine is awful. West Marine provides nothing (have to special order the resistor spark plug). Lehr customer service does not respond to calls. Very few service facilities. This lack of reliability makes one think twice about an important dinghy motor.

              It may be an OK small motor for a lake but not for Hawaii.
              I had to return it and upgrade for 5HP.
              Engine cover has some issues - should be improved.
