I am  interested in upgrading my propeller. The boat came with a 2
blade
13-6  sailor prop. I have an A-4 with a 1:1 gerar ratio. The engine
seems to max out at about 12-1400 rpms at about 6 kts, if memory
serves
me correctly. I want to go to a 3 blade sailor prop to improve the
thrust and maneuvering capability, especially near the dock.  Michigan
Wheel recommends a 12-6 three blade prop based on the data I provided
in
their prop-it- right web survey.
My questions are - what sort of rpms do you get if you have a three
blade sailor prop coupled with an A-4 having a 1:1 gear ratio. What
size 3 blade prop do you have?
What are other sources for props - aside from Michigan Wheel? 
Any other reflections or observations would be appreciated. 
Thanks
