Prop nut/cotter pin question

[todd river]

I had my prop reworked recently. I had a friend who had
tools to help me remove the prop. I have a torque wrench,
but I wanted to know if anyone knew the size socket I
would need & cotter pin as well. My engine is the f-150
4stroke 2006 model. I measured the nut & it looks to be
1 inch across. I am guessing it is metric? I tried to look
it up in the manual. and it only mentions the torque.

It takes a 27mm socket.

Prop torque

ok, I give up, where do I find the torque to secure the prop on a f150txr 4 stroke...or am I over thinking this one? Thanks

Good and darn tight(torque setting), then a bit more to align the holes in the prop shaft with the slots in the nut. For a wrench, just about any X-shaped tire lug wrench works great(prefer chrome plated so it don't rust), hack saw off the 2 sides of the X that you don't need and you've got it! One of those folding tire lug wrenches would work fine also. I buy a 100 count Stainless Steel cotter pins from the nut/bolt/fastener place for about $10 and use a new one every time.
