mcculloch 210 engine in a deep vee hull

[geeman]

Hi forum

Ive been given a Mcculloch 21cc strimmer engine i know its not the blow away performance for more expensive model engines on the market but hey its an engine and its free.
I do have a guy who will give my engine a polish and port it like on perfomance motorbikes and have access to the materials to build a ram air intake and an exhaust system required for tuned length.
Id like to know some basic hull length beam and how deep to make the vee the style of it above the water line im ok with and can cope with sorting something to that part of the build.Can anyone assist me with these i would be very grateful if you could
