1981 Mercrusier lower unit

[troyl]

Hey everyone well i have searched all over the internet and i cannot find an answer to my problem so I hope someone here has some help Today i took my lower unit off so i could change the impeller i got that done no problem I rotated my prop counterclock wise and the shifter shat clockwise so that the splined shaft would turn now i have tried to install lower unit and while doing so I turn the prop counter clock wise so the shaft turns but i cannot get the lower unit all the way up so i am not sure what the problem might be it just seems like the splines on the shaft won't go into the gear in the upper housing I would so very much appreciate any and all help

Thanks Troy

I replaced my impeller last year for the first time in my 1984 mercrusier 470. Look at this link and it may help you with your 1981. Look at this web site and you may find your same lower unit. It is a pain in the butt. It helps with two people on the insallation.
