Best prop for 1970 Johnson 40hp?

[Hercplt]

I will need to replace my prop. In absence of a shop manual at the moment, can anyone tell me what size, pitch etc I should be using?? Motor is a 40E70.
The motor will be hung on a small 15 foot fiberglass boat. Pretty basic application I guess.
Thanks for the help in advance.
