I bought a Ranger r72 not too long ago.  It is in immaculate condition with a 115 Evenrude  Intruder motor.  The dumb thing is in showroom condition and all of the manuals came with it.  The problem being that I don't know what is holding the prop on.  In the owners manual for the motor, in the previous owners handwriting, is "Prop Lock Western Wind followed  by a 15 digit number.  I have googled this to no avail.  The "lock" has a copper colored nose cone over the prop nut that has a slot in it about 3/8" long.  I have no clue how this set up is supposed to work, can anyone shed some light for me on it?  Thanks guys and gals, I am new to the bass boat world am discovering that my knowledge of 40 years ago is not serving me well!
 

Sorry no clue ☹️

Why not ask the guy you bought it from?  Or, maybe try a locksmith.  At least they'd have the tools to remove the locking device, even if it had to be cut off.

You should post a photo of the lock to see if somebody can ID it for you. 

 

I'd guess the slot is to insert a key to remove the cap while the 15 digit code is for key replacement purposes.
