I have removed my direct drive set up (42 inch prop) from my UH13pt,
and rebuilding it as a belt reduction, with a 54 inch prop, powered by
a 23hp Briggs. (Thanks Marquis for your input).
If 6.25 / 12 pulleys - is that the pulley diameter ratio?
How many rudders should I use?
How tall and wide are the rudders?
Is a trim wing needed?
