Question ... when I did my 36 lb Min Kota calculation afew years back, the
answer I got was about 1/4 hp. Would you mind sharing your calculation (I've
since upgraded to a 55 lb thrust)? Thanks

I have a 9'2" Sevylor XR-86 inflatable. It is powered by a 36 lbs Minn
Kota Endura motor, about the same thrust as a 2.0 or 2.5 hp gas
engine... OK, it doesn't plane. I'm not so sure it would plane with the
maximum 3.5 hp motor. I'm not so sure I'd want to do that anyhow.

It's your choice. The small two cycle and four cycle outboards are each
reliable, and don't burn a whole lot of fuel. With the four cycle, you
don't have to mix oil in the gas can, and their exhausts smell better. I
use a no-cycle outboard on my inflatable: an electric trolling motor.




Wouldn't there be a way to compare pounds of thrust? My motorguide
trolling motor produces-oh, I really don't remember-something like 65
pounds of thrust, maybe. How many pounds of thrust might a 3 hp gas
outboard produce at the prop? A similar number? Larger?

The electric trolling motor is enough to push our rubber ducky around
the harbor for a couple of hours, but if it craps out, no worry. We have
oars.
