what percent nitro to use in these motors

Does anyone know what % nitro I should use in the following motors? cmb 100 (16.4 cc) and pico 67. I am currently running 65% nitro in both motors. Is that ok?

It sounds about right. I would use 60+ in those boat engines with plenty of oil.

If the CMB has a needle bearings on the rod ends, you can use a much lower oil fuel than traditional boat fuel. Teh Picco, I would use a traditional high oil boat fuel. 60 to 70% nitro sounds fine.
