New Prop & Shaft - install prop questions

Hey everyone,

I just got a new Campbell Sailor prop and a new stainless shaft. Not sure I installed it correctly (or I'm being too fussy).

Here's what I did:
  1. Key looks good with rounded edges, slides easy in both shaft and prop.
  2. Prop fits well on taper, no rocking.
  3. Slide prop on shaft w/o key and mark shaft with a sharpie at highest point
  4. Remove prop, put key on shaft, slide prop on..couple of mm away from my line
  5. File top of key a little..try again..still a couple mm away from my line
  6. Repeat filing key and testing a few times..still can't reach the line..and now if I shine a light I can see a gap between key and prop keyway.

I can't understand what's holding the prop from sliding back to the line? Should I remove some width in the key? Key slides well in both keyways.

Now that I've got some space between the key and the top/bottom of the keyways, should I get a new key and start over?

If I give the nut a turn with a wrench I can hit my line, but not without the wrench.

Am I over-thinking this?

And, I can't find any info on the proper torque for the prop nut. I've seen everything from 10 to 100 foot pounds.

BTW, the small prop nut is to go on first, followed by the larger...most do it back wards You may want to confirm that with Norm

I would say as long as you can drive the prop fully on with the nut you are OK.
