Tips for Installing New Impeller on '67 80hp Evinrude

[jetskier16]

I have been restoring an old runabout for a few months now (you can check it out in the link in my signature) It came with a 1967 80hp Speedifour Evinrude outboard. I decided that I should replace the impellar. I have never done this before nor have I really worked on outboards.

Im using a Seloc manual to help out but since it isnt very good I was wondering if you guys had any tips or general advice when I go about doing this.

Thanks in advance!
