Re: Lehr Propane Outboards

I inherited a 5hp with my monohull.

A larger Tohatsu we have couldn't be pull started by my girlfriend. So, we used the Lehr all summer. It worked well. None of those carb problems everything else has. The little disposable propane cylinders were what we used for the summer and it was ridiculously expensive. But, it served its purpose.

I thought we had a great little kicker in the Lehr 5hp, until it came time to put away the dinghy for the season a few weeks ago.

The motor had been on for 4 months. Tohatsu has been on for years at a time between removing it from the transom. Well, the Lehr fused together due to corrosion. 4 months on the transom and you couldn't spin the handles that are supposed to rotate the bolts that clamp it to the transom. I used penetrating oils, time, tapping, heat, you name it.

Ok, I decided to get more leverage.

I put a pipe on the handle to spin it. Predictably, the handle broke off the bolt. It's just cheap plastic on these after all. It wasn't as weak as I thought because it actually twisted the bolt!! The bolt didn't budge, but the metal of the bolt twisted like wringing out a rag! I put some vice grips on to replace the handle. The bolt just twisted like a piece of pasta!!! Never once budging to release the motor from the transom!

Eventually I gave up. I had to take a pair of bolt cutters and just cut the thing off my dinghy.

Couldn't believe how the dissimilar metals welded together or how cheap the clamping bolts are that they'd twist like pasta.

The motor itself ran great. Never a single issue other than the small propane tanks running out mid channel at night every single time. But always started right up and 90lbs girlfriend could pull start it too. But the hardware was not up to par.

Still may keep it though.

HopCar,
Thanks for the sincere assessment. I thought the concept was great and we could be free of gasoline while we traveled. It is still a good concept and some day it might become a dependable dingy engine. Or, as you said, an excellent aux for small sailboats.

Sorry you had to deal with that.

I always put TefGel on transom bolts. I use TefGel for automotive and HAM radio stuff as well. It works.

Yeah. I guess next time. I have never had to do that in the past two in all my decades of boating. I’ve never had an outboard stick like that before. Times they are a changing. LOL cheaper and cheaper materials.

Re: Lehr Propane Outboards

Just bringing this post back from the dead. Any body have any info on where to purchase parts for these outboards?

Lehr is out of business and is part of the Onyx corporation. I called and they have no contacts what so ever from that division.

West marine was a dealer but they don't have access. Also tried Michigan Motors who used to be a dealer with no luck.

I did find a service manual online and I have part numbers but Google searches coming up empty.

Looking for a shift lever which is plastic and broke off. I figured while I had it apart I'd order a couple other items to refresh it.

Anyway, if anyone has any info, it would be greatly appreciated! Maybe there is a warehouse out there with some NOS on the shelf.

All the best,
AJ

Re: Lehr Propane Outboards

I have a Lehr 5 hp in my garage with very little use. It had a known manufacturing defect that created a propane leak under the cowling. Lehr never contacted me about the defect and I discovered it when we were in a foreign country, far from warrantee repairs. A propane expert in Mexico repaired the <extremely dangerous!> defective parts. I bought a replacement gasoline outboard and have never trusted or used the Lehr since.
It might be OK for puttering around on a small lake but if you are doing any serious sailing, the Lehr would work better as an anchor. I would not waste much money on repairs.

Re: Lehr Propane Outboards

Yea, not doing anything crazy with it. It came with the dinghy when I bought my current boat. I can see the flexible fuel line is severely dry rotted and I will be replacing that as well. That is actually a part I can purchase...but anything else, it looks like I'm currently SOL.

Re: Lehr Propane Outboards

There is a Lehr Outboard Owners group on Facebook that is a useful resource for orphaned Lehr owners.

Rafreeland, thank you for your response. The link requires creating an account . I was hoping there would be a way for me to read the posts without one.
