Hello,

 

I bought Sail drive style 63mm hub 15-1/2” 2 blade feathering / Variable pitch 
J-Propeller for my CnC 99. Installation was easy following supplied 
instructions.

What is left for me is to find the right / optimal pitch for my boat, that I 
can start from, and adjust the pitch later on the water, if needed (better in 
warm water -😊).

Can you help me with that, please? 

 

Here are details:

*       The prop that I bought is Sail drive style 63mm hub 15-1/2” 2 blade 
feathering / Variable pitch J-Propeller
*       When I look from the stern, the prop is rotating counterclockwise when 
in forward gear.
*       I have C&C 99 yacht with Yanmar 3YM20 3-cylinder 20hp Diesel engine and 
SD20 - YM1 sail-drive.
*       I use the boat in lake Ontario about 50-50 for sailing and motoring

I hope you can give me your recommendations to find optimal pitch based on that.

 

Once I will know the right pitch, I will be able to set correct notch based on 
instructions on page  11 of the manual.

 

Thanks in advance for your help,

Sergey
