Hydrocopter propeller thrust test

The nice looking Sensenich propeller made engine rpm´s little to high, also suffering thrust in open water and soft snow, we also had a very old prop partly broken at one tip, so after fixing that and balancing it we made this test, 44kg/97us lb compared to over 70kg/154us lb is remarkable, and after some driving the "feeling" confirm the figures. Also at WOT we have 6kg(/13us lb and 2800 rpm, engine rated 48hp @ 3600rpm, (industrial ver. of Porsche 356 B) equipped with WIDO (Willy Dost) reduction 1:1,68
Sensenich got the figures from the old one when we order, but made more narrow blades on outer 1/3 part and added 2" diameter.
