IVO Prop Inflight Adjust

[chuckitt]

Last week we installed the inflight adjustible kit to George Thomas Dixon Twister. This gives him the ability to change the pitch in his prop blades while driving the boat. Take off and get on plane with less pitch and add more pitch to bring the engine rpm's down to improve your cruze rpm's and save fuel.
George had called me to let me know it was the best improvement he had done to the boat next to adding the Mikuni 42mm carb on his 35 HP Briggs.
Today, George brought his boat to the shop to take me for a ride so i could see the benefit of adding the inflight adjust kit. We took off and ran the engine up to 3900 rpm with the boat running 23.7 mph in heavy wind. I started adding more pitch and got the engine rpm down to 3250 and still maintained the 23.7. Adding a little more pitch and we started loosing a little speed. We were still in heavy wind and deep water. George said he got better results running in skinny water.

Here are some pictures of the kit.
Thanks, Chuck
