I have the 2GM 13 with a Martec 14x10 prop. I get 6.4 knots @ 3100 rpm in flat water. If you have vibration, check the cutlass bearing first. If you see what looks like rubber oozing or squeezi9ng out, replace it.

If you have a Martec folding prop as I do, you should also check the prop for wear. In new condition, the blade tips should be prefectly aligned with each other. If the offset between the two tips is more than 1/4 inch, it is about time to rebuild or replace it.

I would like to hear from people about the props they are using. My Martec is now worn out (has been rebuilt once) and I am shopping for a new prop for next year. I am looking at Varifold or Flexofold geared props. These companies are recommending larger props with different pitches. I would be grateful for any experiences others have had with props other than Martec.
