Mike was very helpful in the selection of size and pitch of a stainless steel prop to replace a factory aluminum. Service was excellent and delivery fast. Pitch was perfect as the WOT RPM remained at the top of the factory recommended range. Sadly, I have not noticed any significant performance increase as my top speed remains the same as the previous prop but that is not their problem. I will continue to tweak engine height and tilt positions to obtain the best performance.
