Red face Prop Nut Torque

Hi, I have a 2002 X5 with the 310hp predator and standard transmission. Does anyone know the recommend prop torque? Also can you confirm it is a LH rotation. Thanks.

I've never heard or torqued a prop nut. But here's what I found..........

Inboard Propeller Installation Procedures
Put propeller snugly onto shaft taper WITHOUT key in either keyway (propeller or shaft)
Make usre the propeller is nug and ther is no side to side movement by gently moving propeller back and forth
Make a line on the shaft with a non-graphite marker at the forward end of the propeller where is butts up against the shaft taper.
Remove Propeller
Put key into keyway on shaft taper with radiused or chamfered corners (down) in shaft keyway (if propeller shaft keyway has radiused corners)
Put Propeller onto shaft taper
Measure the distance between the back of your propeller hub to the strut bearing. The distance should not be greater than your shaft diameter to avoid possible vibration.
Check to see that propeller moves back to the forward line made in Step 3. If it does, skip down to Step 9, if not, preform the following;
Remove propeller from shaft
Place a file on a flat surface area or work bench
Run opposite end of chamfered key back and forth over file (to remove any burrs) with downward pressure on key until side being filed is clean.
Install cleaned key in shaft keyway with camfered corner side down in shaft (the cleaned, filled side up in keyway)
Replace the propeller on the shaft and fit snugly on taper. Check to see if it reaches the line made in Step 3, if it does not line up then repeat these steps again.
(NOTE: a vise can be used to hold key and then filed, but care must be taken to not tighten too much, causing burrs and irregularities on key.)

When propeller hub moves to correct position, install propeller nut on shaft and torque to seat the propeller. Install and torque jam nut also, if your shaft is so equipped.
Install cotter pin at end of shaft

My 94' 205 owner's manual says torque to 50 ft/lbs and then insert cotter pin.

Same here. My '05 with the splined shaft calls for 50 ft./lbs.

It's worked for me for 19 years, but them boys is sore each prop change, after several comparison runs to see if it's tight enough and it results in a lot of screaming on my behalf! I have a bunch of trouble stuffin'em in the socket!
