Max Prop blade setting angle/pitch

[Orla]

I have a classic 3 blade max prop, which I removed yesterday for servicing.
I forgot to take note off the angle the blades were set to, I have the installation PDF which says I can get the correct angle if I know the following:-

prop dia (20in)
Yanmar 4JH2-HTE 75hp
Gearbox is a KBW21 with a reduction ratio of 2.62

I still can't figure out what the pitch should be, from the chart on the PDF..

Can anyone please enlighten me

Many thanks
Doug

Many thanks sailorman.
Darglow came up with the answer, and very quickly.
They said 20 deg should be about right, or 18 deg if I want to play it safe, I'll go with 20 and see how it performs..
