Are you using stock solas or did you buy them pre-pitched. What pitch and type did you go with ?

Well... 13/19's pitched for torque I assume. You'll never hit 55 mph like that man.. horrible just horrible.
Then again, I have amps, subs, a tower and a non removable bimini like the new E series so I doubt I'll break 50 ever again.

When you do a side-by-side comparison of port and strbd, looking at lateral profiles, I'm curious if you can see the pitch differences on the trailing edges. It could be very small, like 1mm, but you should be able to easily tell if you rotate it on a smooth surface up against a ruler.

At any rate - I would take notes on the trailing edge blade angles, if you ever need those. There are devices for measuring the angle, but I find the simple distance at fixed points on the blades to be the most accurate, at least in amateur settings.

How many hours were on the boat and did you think of changing the wear rings to make sure you eliminate all cavataition

It is such a shame that something so pretty will never be seen again once installed! Please report back with results!

Initial results are ok , I'm pulling them out to have them repitched , good holeshot , but stops after that , pitched way to low , was hitting the revaliminator on the top end , had to back off power to 75 % to keep it off the revaliminator !!
