Prop Sizing and Placement

[GregH]

Morning Folks;

Thought I would start a new thread about the prop I have as I wasn't sure about its size due to being able to go 2-3kn at idle, plus vacuum readings - but the engine needs a good tune up in the spring before I can feel good about those numbers.

The pics below of the prop. it's a 13x7 2 blade in an Alberg 30.

- The gap between blade tip and top of notch is about 1/4"
- nothing is bent or loose for the prop to ride that high in the space. it is angle of the shaft log as built from what I can tell.

As some have mentioned - maybe going with a 12x 7 or the indigo 3 blade (I only cruise about) 10x7

The small gap at the top worries me, but I have no experience with this and so looking at discussion/advice

Sorry for the out of focus....
