I was reinstalling my prop this weekend (s.s. 19p merc outdrive)and i noticed that the washer that holds the nut and securing tab-washer has groves in it that i thought whould also seat into the outside of the props hub. <br />But after instaling it it doesent lock into it.<br />do i have the wrong size of spacer washers<br />or is this normal?<br /><br />purchased the boat last year and did not lose the prop or have it come lose, but i sure dont want to either,<br /><br />I dont see how the locking washer with the bendable tabs can work if it does not lock into a fixed position.<br /><br />thanks<br /><br />russman
