hydromotive intimidator q4's , i got them a last year for my fountain 35 2000' and never used them.. they are brand new... i am looking to see what pitch they are ...

and i see a 28l .. maybe it is 28 pitch left side ? how do i know if these were labbed ?
i remember they being 26 or 28 x 15.5 .is that possible ?

here are some pics

some more pics

The 28 L is the pitch and the rotation. The diameter is 15.5".

Your props look to be stock, not Lab Finished.

Are those stampings on the hubs the props serial # from Hydro. or stampings from a prop repair shop?

Not sure. I didn't think they were Hydro's.

Bottom left is prop shop stamping
Top Left Hydro stamping

so they are 28 x 15.5 ....left ..i have the rt and lt new then...

If you are talking about the pictures, obviously the upper left is the Tom's numbers cast in. But what numbers are you seeing in the bottom left picture?

I thought we were talking about the hand stampings. Are we? Top rt. A prop shops
