Cat prop size?

I am curious what the prop size and pitch would be for a 38'-40' catamaran running 25hp dual Kabotas? I understand there are variables involved but would like to get an approximation. What are you running on your cat? Thanks.

Re: Cat prop size?

We would need your displacement, gear ratio, max RPMs and power at those RPMs, LWL, BWL an depth of axle below waterline to make a calculation....Regards
