[easyloader]

I am planning on taking off the outdrive to prep it for paint. I noticed on this drive thee one nut that looks different and you can't get at it with a socket. (see attached) I'm not sure what tool I need to remove this.
any help is appreciated

Nope, it's a 9/16 nut with a nylon anti back off sleeve on it. They are called Nylocs.
To remove the drive put the shift in forward, remove the trim ram ends, then remove the six nuts. Pull.

that's a anti-theft locknut from McGard. without the key you will need a small cutoff wheel to split the outershell off and then needle nose or small chisel to remove the nut part.

Ayuh,.... Search the nooks, 'n cranies of the boat for the key,....

oops, doesn't look it to me but I'm just a windbag any way.

The key to remove the lock will look like the gold color tool where a 5/8 socket would fit seen in the following link. http://www.mcgard.com/index.php/mari...rn-drive-locks

You'll also need a mercruiser engine alignment tool since you're removing the stern drive.

I just bought the boat and will search it for the key. Who would be afraid that someone's going to steal the outdrive?
Thanks everyine

there worth 5 grand, minimum $2500 for a newer drive.I always had my customers tie it to the front of the engine

And a good thief can pull one off in probably 5-minutes. Easy cash.
