To the crew at Holland Propellers:

Just a note of thanks for indicating and eliminating the vibration I had with my boat.

Your Prop Scan treatment proved to be more exact and was able to fine tune each propeller with better results than traditional methods.

I am now able to run the boat at higher rpm's without fear of damaging my drive-train.

Thanks once again
