Rudder and prop shaft kit recommendations

[Turbotaz]

I have hand built wood frame and fiberglass 55? l catamaran with 22?w
I need recommendations for rudder and prop shaft kit for it. I have twin leopard 4082 2200kv
Esc180 x2 and lipo battery 4s 14.8 x2.possibly upgrading to 240esc for 10s And I want to go as fast as possible. Not racing

You would certainly need different equipment if you ended up going 10s.

For 4s I see no reason why a 3/16 flex shaft setup wouldn't work well.

I have not found that many places offer setup "kits" per say. Usually you end up having to purchase all the components separately....

There are so many unknowns here to recommend the right parts. Is your CAT an older model where the strut would mount to the transom or newer designs have the mounting forward and under like this one:

I?m middle of the building the hull looks like mystic 5000 Geico, it?s my first time building a hull, size 55?x 23?, I think it?s too wide but it?s too late for me the change the dimensions, hopefully next one. Now for the motors should I go for 5692? And esc 240?
