    Change 05pump down to a old gp1200 one.

    if I have a 05 1300 is just to replace the pump with a old gp1200r pump?

    Plug and play?

    if you have the shaft, yes. if not, you have to press off the shaft and put it in the other pump

    I will replace the whole pump including the driveshaft.

    That will work?

    Only difference is the larger hub. Props will have a mismatch but still work with each other.
