bare foot wader Posted November 28, 2012 Report Share Posted November 28, 2012 looking into one of these for next year, anybody have any experience? good or bad thinking about using one on a jon boat for small backlakes, canoe on portages, etc...trying to find out run time off propane vs gas, I'm thinking a 5lb propane tank would be lighter than equivalent required amount of gas for the same run time??? just a complete guess/hoping that could be the case would guess easier to maintain, carbs fouling, no mixing, easier starting, etc http://www.golehr.com/docs/specs/specs_5.pdf Link to comment Share on other sites More sharing options...
BillM Posted November 28, 2012 Report Share Posted November 28, 2012 I don't think there's anything easier then a small 2 stroke for a back lack/portage motor. Link to comment Share on other sites More sharing options...
Joeytier Posted November 28, 2012 Report Share Posted November 28, 2012 I'd be interested to see how many hours you could get out of a 1 lb. tank. Seems like a great design. Link to comment Share on other sites More sharing options...
Lip-ripper Posted November 28, 2012 Report Share Posted November 28, 2012 Very cool! I watched the video on the website. No priming, no choke, 99% less pollutants and using a cheaper fuel source... seems like a solid idea! Link to comment Share on other sites More sharing options...
Terry Posted November 28, 2012 Report Share Posted November 28, 2012 I prefer a 2 stroke for back lakes I am always setting the 4 stroke down the wrong way the the oil gets into everything but if the bottles last, it would be cool Link to comment Share on other sites More sharing options...
woodenboater Posted November 28, 2012 Report Share Posted November 28, 2012 Very interesting but what will make or break it for me will be cost of the outboard and running time (approx). If a single 1lb cannister can run as far as say a gallon of gas, it'd be worth looking into further, more or less. I could see using a 10lb tank with this or even a 20lb. I think it's telling that they're not publishing these details (that I could find), esp the run time and/or distance at a given speed. Something we can compare to a gas kicker.

Roy Posted November 28, 2012 Report Share Posted November 28, 2012 Taken from their site. Fuel consumption is similar to an equivalent gas-powered outboard. A recent test by Boating magazine found that the 5-hp Lehr could push a 12’ aluminum boat 4.5 mph at 3300 rpm while delivering 24.3 mpg. At 4600 rpm, speed was 6.2 mph at 3.1 mpg.

woodenboater Posted November 28, 2012 Report Share Posted November 28, 2012 Thanks Roy. Saw that but propane is measured in lbs up here so I wonder how that translates from mpg ? I'm better with charts so a simple bar graph would be easier for me to grasp Good to see a company looking for alternatives and I wonder if they have any plans for outboards up to 9.9 ?

BillM Posted November 28, 2012 Report Share Posted November 28, 2012 You're going to burn a lot more propane then you would in a similar gas engine, no doubts about it. Link to comment Share on other sites More sharing options...
Roy Posted November 28, 2012 Report Share Posted November 28, 2012 4.2 pounds of propane is roughly one gallon at 60F. So at 3300 rpm you'll go 24.3 miles. If what they say is correct, the mileage goes way down at 4600 RPM. Link to comment Share on other sites More sharing options...

Terry Posted November 28, 2012 Report Share Posted November 28, 2012 (edited) The suggested retail price of the 2.5-hp model is $1,199; the price of the 5-hp engine is $1,919.

aplumma Posted November 28, 2012 Report Share Posted November 28, 2012 I would check also what support there is for parts and people who can work on them if you can't. It sounds like you want to go to some pretty out of the way places and while it should be durable it would stink if you had to get parts that are order in only.

bare foot wader Posted November 28, 2012 Author Report Share Posted November 28, 2012 You're going to burn a lot more propane then you would in a similar gas engine, no doubts about it. would it be a lot more? I thought it's only about a 10-15% difference? but propane is cheaper and are supposed to be cheaper on maintenance...or in my case don't need to worry about carbs gumming up for an o/b that is only used about half dozen times a year Link to comment Share on other sites More sharing options...
Fisherman Posted November 28, 2012 Report Share Posted November 28, 2012 If you google it there's a video, the guy says a 5HP will run 1/2 hour at WOT, the 2.5HP will go 1 hour at WOT on the 1lb cylinder. A 1lb cylinder is roughly 1/2 a quart/litre of gas, so 8 x 1lb tanks would make about a gallon. Unless my math is really bad today, that would mean the 5HP would go about 4 hours on a gallon, hmmm. I quit. Link to comment Share on other sites More sharing options...
Tootsie II Posted November 28, 2012 Report Share Posted November 28, 2012 (edited) You members won't like my reply, but they should ban them in Ontario until we get a hefty return deposit on those 1 lb propane bottles. I am so sick of seeing those things discarded all over the bush in Northern Ontario. Edited November 28, 2012 by Tootsie II Link to comment Share on other sites More sharing options...
