OK I checked my prop and here’s the numbers.  Note: I gave Catto the following parameters:

HP 185-200

Cruise RPM 2760

 

What he recommended and I purchased:  64” Dia. 76” Pitch, Red Line 3100.

Joe, funny you should mention.  I was just about to call Catto and order up a prop.  May as well wait for a few more details from yours.  How was your experience with Catto?  How long was the lead time.  What was the final pitch you settled on? 

 

With my new engine I need a little more pitch if I am truly going to be the fastest kid on the block.  Either that or the ability to turn the prop a little faster... hmmm

I’ll try to remember to check the pitch tonight and report back.  Catto is good to work with but he’s also a popular guy, so his lead time is out there (and you may want to pad his estimate a month or two just so you aren’t disappointed).
