How easy should the prop turn by hand

Have a 88 prostar and was curious to see how easy the prop should be to spin by hand when the boat is dry.
Thanks.

on my 95 it spins freely... how's the cutlass bearing look?

It looks good as far as I can tell. The prop take both hands to turn. I would classify it as hard to turn by hand for sure.

There should be some drag when turning the prop so if you're use to an I/O or outboard it will spin way harder than those. There should be no up and down play in the bearing and the bearing material should look uniform all around the shaft.

If the boat has been on the trailer all winter and you're trying to turn the shaft it will feel extra tight until you run the boat in the water.

Thanks for the info. I had read some posts about being able to turn the prop with one finger and that seemed almost impossible to me considering the strut and shaft packing. I ran it for a long time Friday and no vibration and the packing nut never got hot so I think I'm properly aligned. May unbolt the coupler to see if I'm aligned properly.

Posting the obligatory "How to correctly align your propshaft once in the boat's lifetime" doc.

Do it once, and you'll be able to rotate the prop with one or two fingers. I can do it with one, but it hurts. Two is a more reasonable measure on mine. It made a significant difference in smoothness when I did it.

Needing two hands suggests to me that you should do this.

Once aligned correctly you should be able to spin the prop with one finger.

My 87 poweslot was always rather stiff. Almost a two hand deal, but fine when in the water. Certainly an alignment check won't hurt.
