Lose prop?

[Neverenough]

2008 220 ...... I was doing my normal snooping around on my boat just looking at stuff and noticed that the prop was kinda lose. Nut on pin is in but I can move the prop a little back and for and the shaft is not moving. Normal or should it be static?

It shouldn't move on the shaft. I would check the key to make sure it has not been rounded and tighten it.

you need to get some valve grinding compound and lap the prop. google: how to lap a prop, and i believe correctcraftfan instructional will show up.

Thanks Gride. I have been around boats my whole life and never knew about lapping a prop. Makes since. I have done cylinder heads and valves before but never a prop. Noticed something in the article I read. The boat he was working on had two nuts on the shaft. Mine only has the one and its deep on the shaft where the cotter pin will not go through it. Any thoughts?

i don't remember the two nuts(haha), but basically you should have a prop, key, nut, and cotter pin. i use a harmonic prop puller, but the clamps are fine also. just get it off the shaft, lap it, clean it, and put all the stuff on. get a new nylock nut and screw it on until you can put the cotter pin in and seat the prop. others on here can give you a more detailed how to, but a little bit of sweat equity will get the job done fairly quickly.

if you lap, use only the FINE compound....not the coarse.

Just a thought. Make sure the bolt is tightened to the 30-35 ft-lbs of torque. Lap fitting is a pain.
