First I have to tell you that I'm a Lehr dealer.
That said, I've owned a Lehr 2.5 for about two years now and I love it.
It replaced a Suzuki 2 cycle that was a pain to start after not using it a month or more. My use pattern is that the engine
will sit unused for long periods of time, then I'll use it a lot for several days.
After it's been sitting for a long time, I need to bleed air out of the fuel
line which takes less than five minutes. After that it will start on the first or second pull every time.
Last week I loaned my engine
to a customer. I told him I thought he'd be happier with the 5.0 but to try my 2.5 to see if he liked the propane fuel
. Sure enough he came back and bought a 5.0 Lehr. He wanted the largest engine he could easily lift
on and off his dinghy but he didn't need to get it up on a plane.
I think the 2.5 would be plenty for a Walker Bay, as long as you are happy at displacement
You can expect about an hour's run time at wide open throttle from the one pound cans. I use one of the 11 pound fiberglass tanks
as my main fuel and carry a can as a fuel reserve.
If you decide to buy one, I'd love the opportunity to quote you on it.
