What is a good starting point for my FF.12's prop? Centerline of rear sponsons????

I am sure someone more knowledgable will chime in...but your rear sponsons are supposed to be out of the water. So, I think you set it up so that your tub is level to a surface...measure how high the botttom of the front sponsons are from the table...and center your strut barrel at the same height...

As an added note, I tried what you are talking about, actually, with the top of the strut barrel even with the bottom of the rear sponsons. I got a lot of cavitation. Might be my setup, might be my prop...but I went an eighth of an inch deeper, and it worked better...then I went a little deeper still, and again, it seemed to work better.

This was not with a FF.12 though...it was with the lil rascal I was messing with.

with the boat sitting on the front sponsons the rear sponsons should be about 1/8" off the table with the boat sitting level.

The center line of your strut should be at that table level. so about 1/8" below the rear sponsons

Paul, I'll have some soon. I'm mounting hardware and such now. Waiting on my motor mount to come in. If it does not show up soon, i'll just make one myself.
