Next step in my tug build spending spree are the propellers......
I'm not planning on any super competition towing, so what props should I choose; I have steerable Korts and need a 70mm prop.
Now should I go straight for the second mortgage with 5 blade Kort props, or how does performance rate with 4 blade Kort props, or 4/5 bladed 'standard' props, bearing in mind the price comparison is from over £40 for a PropShop 5 blade kort, down to £17 for a 5 blade, 70mm Raboesch Type A.
Ok I understand you gets what you pays for.... but is there a really noticable difference at the end of the day......
What do you serious competion Tuggers have to say??
Thanks

4 blade kort will do you fine.
Thats what mine run on.

I agree a four blade is more than adequate.
Five blades increase power output by about 20%.
' Prop shops' are without equal in my mind BUT ' George Sitek's' are by far the most economical if you are on a budget and still want a proper Kort prop.
A standard prop in a Kort is very inefficient.
A plastic prop by Raebosh is seen by many as a perfect compromise. Though of hand I do not know there sizes.
Just my opinion
