prop for a toon

[MH Hawker]

I am starting the process of getting a new prop for a 20 foot toon I recently bought,I have a clamp on inductive tach on order and thought I would start off by identifing the existing prop, I belive it is a 11 pitch it is from a nissian 1988 ns40c,at present time i do not have the WOT rpms, and speed is around 25 mph will verifie with GPS on next trip out, the prop origional color is white and has limited markings , japan is stamped on the inside on the hub and a 11 and a J stamped into the blades, and acording to the parts book that would be correct on a standard prop, any help idintifing would be appricated
