Dan,
With the power today's engines are making and what race water conditions mid race, 35" I feel is not going to be desirable.
37-38" would be optimal.
If your building for yourself it will meet the rules IMPBA & NAMBA.
but if your building to try to get your boats racing, I would rethink your length.
If you are building for SAW or oval records, if you could keep it on the water it would prolly be a rocket!
Just my 2cents of experience.

Dan, I am not being critical of you endeavor, I just what to help and make something usable by the masses.
Sport-40 IS one of my two favorite classes.

Speedmaster universal motor mount will fill the bill also

I can easily make it longer /wider ect. I am building it like my gas sport, the sponsons are built separate from the center. Also the rules are such that the impba boat is slightly different than a namba version. the namba hull will more likely resemble the gas boat, the after plane section of an impba boat has to be wider.

Awesome,,
I look forward to seeing what you come up with.

Jerry at Seaducer can also tailor his mounts for specific motors in 4" rails. He recently assembled a 4" drop mount for a 45 motor for me.
