I just wanted to give a big thank's to the folks at Sensenich for all the help they gave me with my prop situation, after I got my boat repowered with the new WaterThunder LS6 and put the 2.68 gearbox on my boat Thunder and I decided that a two blade Q series was the way to go but the motor ended up being a bit much for the prop and it did not preform the way I expected, the motor was turning more RPM's than I wanted it to for the speed I was getting plus there were some blemishes on the prop that normaly would be no big deal to most folks but because I work with the state and feds doing Rescue work the boat is well looked over and inspected so the Blemishes had to be addressed so I talked to Don and Charly at Sensenich and told them what my situation was and without hesatation they told me to send the prop back and about a week and a half later, I not only was given a great deal on a three blade set up but they refinished the two blades that I all ready had and they looked Beautiful but they also cut the blade length down so it would remain 78 " and sent me the third blade and hub to go with it and made me an offer I could not refuse to switch over. I put the new prop set up on this week end and after I set the pitch and tracked the blade tips and the motor was turning the RPM that I wanted, it was off to the river to try it out and need less to say I was shocked at the performance differance between the three blade over the two blade the boat had unbelievable snap and power and the big thing it was real Quit, I even got real brave and tried it on some wet river sand and to my surprise it went accross it efortlessly and I could not tell a whole lot of differance between dry ground and the water so it would be a understatment to say that I was pleased with the results and with the service I got from Sensenich the are an Awesome company to deal with
