12" 3/16ths id brass tube on the propshaft, i used to press the propshaft snug against the drive dog to see the angle on the setup board, i cut a slot in the setup board that fits the lower unit...To be honest my Cav plate is parallel with the propshaft but its not all that important
unless you want to try somebody else's setup.
you can remove the prop and slide on a tight fitting tube thats say 12 inchs long then put the incedence meter
on there.
as long as you use the same procedure each time then you will be able to get very accurate results
doing it either way

Bingo.I just use a digital caliper, to measure from the table to the underside of the cavitation plate, at the furthest forward point, and furthest backward point. This tells me how much positive or negative I have in the lower.

You got it buddy > Discovered that 2 years agoI got a little digital angel finder from Harbor Fright. Works GREAT!

The unit I bought from Menard's is a piece of junk... can't hold onto a value- too sensitive... think I paid ~$29 for it.If U don't want to pack around Ur set up board . I use one of these digital angle finders in the pits. Set the boat on Ur startup stand set the meter on the cav. plate. zero the meter and then u can increase or decrease the prop shaft angle from Ur base setup board angle till Ur happy the meters are available from Amazon, Harbor fright ECT.
