Just a bit of credibility for sensenich I had a water walker on my gpu it was a very nice prop but when I went to a ngq on it same size I was able to run MUCH more dry ground and quietly. And on my new to me boat I had a 3 blade r 80" cruised at 3500 min and with 3 people it was closer to 4000 rpm and went to a 3 blade ngr 80" and cruise with 3 people at 3300 and seems to have not lost any top end at 5400 rpm one person and it flies this is all deep water differences in shallow they both do great. I am very happy I went to ngr blades.
