C&C Corvette w/ A4 direct drive shaft size ?

Would anyone know this shaft size or where I can find out ? I am in need of a propeller and I'm going to need to know so I can find out what options I have on the used market...... Thanks

Almost all direct-drive A4s are 7/8" shafts.

While it varied with manufacturer (e.g. Catalina Yachts used 1" shafts on its A-4s almost exclusively) to be certain, you need to measure.

Yep. You can buy a cheap caliper at Home Despot.

By rights you should look at what is on there. C&C generally used 7/8 inch shaft with the A4. My C&C 30 MK1 is 7/8. I think you should measure the shaft and make sure though.

Shaft size

My Tartan 27 is 1" and I do believe that is the size as designed.

Gotta measure.

I can't remember what shaft diameter Jensen used but other examples are 7/8" on the Newports, 1" on Catalinas, 3/4" on Ericsons.
