Something doesn't add up, going from a 17p to 19p should only drop your RPM
300-400rpm. Comp props work well.

Anybody have any experience with the segmented composite props like the
4-blade Pirahana?
Pros and cons from the real world? As always the ads look good.
Most of the use will be for wakeboarding and cruising. I am looking at an
18P x 4 blade for an '86 20' Chapparal with 305 Alpha 1. Currently using a
17P alum 3 blade which will over-rev up to ~5100. 19P x 3 blade alum
yeilds
top rev of 3800 and no pull.
Not keen on SS due to cost and potential damage to lower drive if I hit
something in the water.
Thanks in advance.
