CD-30 prop size

Post by John MacArthur »

For everyone who has been asking about prop sizes: I just got this information from Michigan Wheel regarding proper prop size for CD-30s with Volvo MD-7A motors. Presumably this would be close for CD-28s with the same motor.


" Diameter and Pitch: 13 L 12
Number of Blades: Three
Material: Bronze
Cup: No
Style: 3-blade Sailor
*Price: App. $341.00
*Plus applicable tax and shipping.

COMMENTS:

The recommended clearance between propeller tip and hull bottom is 15% of
the propeller diameter."


Turns out this is exactly what I have, and the clearance in the aperture is just what they recommend, so I assume this to be the original prop.
