Impeller on my 9.9

[carpenterken]

I just ordered (through here) a new impeller for my 9.9 Honda. I'm guessing it's as easy to change as the OMC or Mercs. Is there any thing different I need to know?
Thanks,
Ken.

recently did mine on a 9.9, easy as pie. Hardest part for me was getting the LU off.

Re: Impeller on my 9.9

So I got the impeller and went to put it in and it's way taller than the old one.
IBOATS only shows 2 different ones and they both look the same. Mine is 9/16 tall and the one that got shipped out is 1 1/6 tall. Can some one point me in the right to the proper one?
Thanks.

Edit; I think I found it 18-3100?
