The only carbon fiber prop I can think of that might work on the K&B 7.5 is the one that comes with the O.S. 21 OB and that's too small. Get a X447, it will work. There's lots of other choices, but the X447 is a good base prop.

As jerry said, X447 is a good prop to start with, let you find the needle and set-up fairly easily. After that you can try X450, 1450, H-7, P230, P225 pitched up, P235 reduced,...... lots of props will work with that motor, assuming its on a tunnel?

I have the most luck with a Prather 230 or 235. The GPS also liked the Octura X648.

I have two K&B 7,5 cc outboard. I use P235 prop on a DeepVee fibreglass hull 40".

However, anyone know where I can get spareparts for this engine?
