Sabb engine props

Hi,

I have a '78 Sabb 10 hp with a variable pitch prop. I’m thinking of
changing the present blades that are the long tapered style for the
shorter, fatter blades. While the shorter ones have a slightly less
surface area, their shortness will give the prop a larger clearance
in the deadwood cutout which now sometimes gives a "whop whop"ing
sound because of too little distance from the prop end to the top of
the cutout.

I’m wondering if anyone else with this engine on their BCC is using
the smaller blades and if so, are they satisfied with the performance
of the system.

Thanks,

Stan on Waxwing hull# 22
