Got a slight problem I noticed after last time out after a quick "walk around and shake/prod everything" inspection.
I fitted a new prop about six months ago after an argument with some passing rocks during recovery onto the trailer, and torqued the prop nut to the correct value (not that tight - I think it was 14nm or something but that is what the workshop manual says) and fitted the split pin.
Now there is about 2mm of slack i.e. you can slide the prop back and forth on the splines before it hits the washer underneath the nut. The split pin is still in there so there is no way the nut could come loose.
Is this likely to be a sign of an impending failure of "something" (what holds the shaft into the lower unit?) - I can't see any way it can have come loose as the split pin is still there. Haven't taken it off yet for a look - but the shaft spins smoothly and has very slight play in it, which it has always had since I got the boat - done 110hrs since then.
Just wondering if anybody else has a plausible explanation for this as I can't think of one offhand
