Hi guys. I just pulled off my lower unit to inspect the impeller and sure enough its a goner. It was worn down enough that I can't tell which direction to put the new one in. Its a 99 120hp Force. Thanks.
Good idea Robert. I could also tell by the rubber left behind. I figured out the impeller direction. Its the same as drawn here: http://www.boatpartstore.com/obdrive.asp
Once I took out the impeller and let it sit for a couple minutes it resume its natuaral shape, plus I could tell by the rubber marks.
