Kohler 27 hp
- I have not heard anything about it. Sounds very interesting. What have you
heard about it? 27 hp stock would be about right. I would think removing
the blower and muffler ought to be good for another 1 or 2 hp.
To add a little perspective, I installed a stripped down 25 hp Kohler on my
Thunder Gull and did some crow hops with it. The Gull had a total take-off
weight of about 460 pounds and the 20 foot wing. I ended up with a 54x20
prop to get 3500 rpm static. It would just get off the ground. But did not
seem like enough thrust or speed to go ahead and fly it. The Gull is
aerodynamically clean but had the short wing for high wing loading.
I had also built a motor glider with a 39 foot wing using a 23 hp 2 stroke
engine. It took off and flew just fine.
I think low drag and low wing loading is the key to making these low power
engines work. I am now working on a low drag/low wing loading design of my
own which I hope to have flying yet this season. I'll probably start with a
30 hp 2-stroke but hope to make the Kohler or a 2A042 military surplus
engine work ultimately.

- I was just looking at my Kohler and wondering if I could rig up a belted
re-drive for it when I saw on the [surplusengines] group the following:

Looks like GPAC thinks it will work, at least on the airboats they sell. I
didn't have any of the blower, housing, starter, or exaust stuff on mine
when I had it set for direct drive for flying, probably don't need it. I
also wonder if the 16 pound flywheel is needed.
- basic power to weight ratio problems always arise with the small 4
strokes. If a 4 stroke engine is less than 30hp it is usually way
too heavy for the plane. I fly a plane that requires about 25hp but
the engine complete with starter and exhaust has to stay around 50
lbs or less. I have to use a 2 stroke to get that power and stay
light weight. Any of us that fly with 20 to 25 Hp engines know this.
I hope this Kohler v-twin will be at or less than 50 lbs or it will
be near useless. 27 Hp isn't much so the engine better be very light
Have a nice day and stay out of the trees!
