Hi Pierre,
I didn't see it at first, but it sure does...I wasn't looking in the right place I guess! It says 40 ft/lbs. with a 7 inch crush plate.

I guess I'm a bit confused at the assembly order then...because I have a 2-1/4" prop spacer and a 1/2" crush plate. The 2-1/4" spacer goes directly on the crank flange, right? Then the prop, then the 1/2" crush plate?

Hey guys,
Sorry to ask this, but I'm not following you with regards to orientation. If I have my crank flange setup so it's pointed up at TDC, I would think the prop could go on in any of the 6 bolt patterns...therefore, 6 combinations to try. Am I missing something? Or does it not matter which blade is pointed up or down? From one of the posts above, it seems that there are at least 3 different combinations to try.

Also, do you need to use the crush plate for the Catto 3-blade?

I guess I should also ask about torquing the prop bolts...I didn't get an installation sheet or paperwork of any kind from Catto. I've read that most people torque to 45 ft. lbs. Is that right?

In speaking with Craig Catto, I was informed 1) Yes, the crush plate was required, and 2) The torque he recommended was 42 ft/lbs. done in increments which for me involved three successive settings and torquings until the 42 ft/lbs were accomplished.
