OMC 800 Stern Drive Impeller Replacement

I have a 1978 Grady with a OMC 800 Stern Drive, I believe the impeller is bad so i am attempting to replace it. The Seloc Manual says i can drop the low unit to replace the impeller, so i have pulled the prop, the 5 bolts and now I'm trying to drop the low unit. It seems to be very tight possibly like its never been apart. Any idea on how to get this loosened up to drop down and get to the impeller?

Thanks
 
I took out the 2 on each side and 1 underneath toward the rear of the drive. By dropping the low unit do i need to worry about the shift cable? i'm using a Seloc Manual and its not rear clear about the cable
 
folks on these forums say the impeller can be changed with the upper still hanging on the boat. I have always taken the drive off. Crowley marine might have some factory manual excerpts on their site.
