Water was slick as glass today while testing the Hydromotive Quad IV o/t 27 and 28 pitch propellers.

I ran the 27p first and here are the results.

Hydromotive Quad IV o/t 27, 87.49 mph/gps @ 6500 rpm's, could have turned more rpm's but I was already over my limit.

Hydromotive Quad IV o/t 28, 89.97 mph/gps @ 6400 rpm's, she was maxed out as far as the engine height.

Next I will play with some more set back. I will be adding my Bobs machine shop two inch spacers for a total of 12.5 inchs.
