Splined or tapered shaft?

I Dont Have A Shaft As Yet Was Trying To Keep My Options Open,do You Have Any Thoughts On It,unfortunately Im Fairly New To This,cheers.

I would use a 19 spline shaft. Same as Arneson #6. That would give you a wide selection of used surface drive props to choose from. The prop is the most important part of a successful set up. I would call John Rose at Ellis Propeller. He can make a new prop for around 1,500 bucks. I have a set on the way from him right now.

I ran fixed drives on my boat for years. It was very simple and rugged. Keep us updated on your project.
