What's the difference in the nozzle you have now versus the old
nozzle? Also, when you change impellers like re-propping, do you
change the angle of the impeller, or is it just because it was worn
that you got better top speed and less RPM's?

New style nozzle is shaped a lot different. Fits inside of the drive as
opposed to external.
http://www.nzjetboating.com/jetunit.htm the old style is a T3. New style is
like on the 212. I have a licensed copy of the 770. By Kodiak Marine.
Changing impellers, you change the pitch.

Gotcha. Looked at the link for the guide that has a boat like yours,
nice boat, looks like it'll handle quite a chop.

Not really, will beat the snot out you in chop. So have to slow down. Mine
has more Vee than most river jets, but still fairly flat. Allows you to run
in about 12" of water. At speed, I draw about 7", but you do want a little
clearance. The smaller pure river sleds will draw about 2" at speed. Still
takes 12-18" of water to start. There is so much draw in the pump that in
will suck a 12" rock off a 3' deep bottom when starting. WIll bounce it off
the intake grate.
