My Eagle Tree data with m445

How do you harden a prop?
-t

A really sharp prop is thin and easy to bend along the sharp edges so I heat treat. I bake my props at 600 degrees for 2 hours then let them cool slowly over night.

#2. Just do the 600F step after yo work the prop. Still very hard, but you canbend them a little if you really need to.

Hit 55mph with the m445!

I took a break from balancing and sharpening my next test prop, a Grimracer L42x66, and decided to run my M445 again.

Apparently my driveline has loosened up a bit and is now broke in. I hit 55mph and it is pulling a lot less amps than prior testing. Data below.

Looser/faster water conditions will help pull less amps and make boat faster also.
