I am going to be looking at my lower unit for a few seals that may need to be replaced but i was wondering how much play should there be at the prop. not side to side but out it would move out about 1/4 inch I really cannot go tighter since I have to back off the nut to get the cotter pin in. thanks

Re: how much slop

You didn't say what motor we are working on, but splined shaft, right? There are supposed to be a thrust washer forward of the prop and another one aft of the prop. Betcha one of them is missing (?). Like the aft one. It's about 1/4" thick.
