Thread: Merc Prop

I just did a repower on my boat. My old 40 hp 2 stroke got tired after 23 years of service I put it to rest last week and put on a Merc 60 hp 4 stroke.
Motor sounds and runs great. The dealer added a Mercury Black Max prop and I noticed that it wiggles around a little on the hub. I can move it forward and back 1/8-3/16 of an inch plus it has a little side play, maybe a 1/32 or 1/6". It just seems loose but the prop nut is tight and when I'm running the boat there is no slipping and there is no vibration.

I called the dealer and he said it's normal on some of Merc's props. Something about a different hub. Every other motor I've seen the prop was tight but I honestly don't keep up with all the new stuff.
Anyone have any input on this.

Thanks for the replies, I figured something must have changed over the years.
I looked on the Mercury website and after bouncing around a lot I found some info and it appears it's common on several of their hubs.
