It's a Hydromotive Quad IV (4) 24 pitch LH rotation,

I thought it was a Hydromotive, but wanted to be sure.

If the prop was "lab finished" would it be apparent?


Thanks Again

If Hydromotive lab finished the prop you would be able to tell. On the can between a couple blades there would be a stamp with a series of letters and numbers. The first two letters would be "HE" followed by a series of numbers.

If another shop worked the prop then it's up to the individual shop as to how they mark a prop. Generally a lab finished prop would have a thin leading edge. It may have either a satin or polish finish.
