Thus my original question,....would changing the prop to this three blade kiwi model (at 1200$) disqualify the OD rating?
Yes it would be contrary to
class rule 5.13.3 which states "Propeller, shaft and strut shall be in accordance with the standard installation with a propeller diameter of not less than 356 mm." You can see the standard installation in the diagrams at the end of the class rules.
You do remove the prop and send it back to Martec for reconditioning. They are very responsive. Here is the web link:
