Hey Dick, just installed the 4 blades, and thanks to you it's not the same boat. Much quieter and smoother. Thanks for doing all of the leg work for all that purchased the 4 blade props.

Just installed our new four bladed props and took them for a test drive today. We are most pleased with the change in the boat related to the reduced noise. It made a significant difference. We had Aqua Drives installed when we got the boat and noticed a significant reduction in noise with them. I would estimate that the change to four bladed props has at least as great an impact in noise reduction added to the Aqua Drives. Needless to say we are very happy. Nanci is extremely happy with the ease with which one can converse now while running at cruising speed and the general noise reduction for just relaxing and reading while under way.

We also noticed an additional 1.5 knots of speed. We did not get to the twenty knots reported by Henry Clews however.

Our thanks as well to Dick T. for the assistance in getting the props and the group price.

For the first time since installing the 4 bladed props we took the boat out for an extended trip and into some weather in the Straights of Georgia off the west coast of British Columbia.

In addition to the reduced noise previously mentioned there was clearly less almost no cavitation in the rough water compared to the 3 bladed props.

We continue to be very happy with this change.

T-

Do you have the 100hp or the 110's? With a clean bottom, I hit 21.8 against a small tide. I have never seem 22 ;-)
