Does anyone know what the prop Hub Bold torque should be.

This would be the bolt that goes into the crankshaft and has the cotter pin.

If the hole does not line up at the proper torque I imagine you would need to use washers?

I also would like to know what the hoffman prop bolts are torqued to?

I did not see either of these things in my manuals.

Go to "Files" on the left margin. The Adobe document "Grob 2500 Engine
Assembly and Repair Manual" shows a torque of 100(+/- 20) Nm for the
"Screw, crankshaft/prop flange". This is found on page 63 of the
manual (page 64 of the Adobe document).

I will also attach a zipped file in the "Files" of the Hoffman HOV62
manual which are scanned files I made of the manual.
