I am considering a Catto prop instead of my Hartzell CS prop because of the high compression engine I have (10:1). My cowl fitting is finished and set for the Hartzell in place. Will the Catto prop with a spacer be the same distance from the engine flange to the front of the cowl as the Hartzell?

Thanks for any help.

I fit my RV-8 for a Hartzell propeller and a Vans spinner back plate I gave it 5/16" gap clearance , it was perfect for me . Then I decided to use a Catto 3 Blade prop with a Vans back plate and spinner also used the recommended
2 1/4" spacer . it also fit perfect 5/16" gap . So I would have to say YES !
