help with prop
 

can any one give me advice on a prop for my project boat,basically its a 27 foot deep v hull in which i have fitted a yanmar 440 6ly2 stp,and i have made my own fixed surface drive,ratio of the zf box is 1.23.1,the boat fully loaded weighs 2 tonne,any help at all would great,many thank,seamy.

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.
