It was also 76” vs a
data plate calling for 74”. With that data incorrect, it could have been a
totally wrong prop and may not have even been 88”
pitch.
What is Sam going to
have Catto do to the prop?

Comparison
Just doing a rough back of the
envelope calculation comparing Sam Hodges prop (8" cord) to my prop (5
1/2" cord) and assuming the two props blade profiles were similar, Sam's prop
would have approx 45% more prop area trying to push the air back than my
prop. Small wonder his engine was groaning trying to spin it up to 6000
rpm.
