1200/ 1300 pump?
What is the differnts between the 1200 and 1300 pump drives? can they be swapped?
can I put a 2003 1300 jet pump on a 2002 1200? would it be worth buying( the 1300 pump) For interchange able parts? What is differnt?

I believe the difference is the addition of the impeller housing (2 inches). The rest of the parts are the same, at least according to the part numbers on boats.net..

here is the post on the 2" extention.
here is information on the parts conversion list.
The 2005 and 2006 GPR's have an 87mm Diameter Pump also known as the "high pressure" pump
2000-2004 i believe have the 85mm Diameter Pump
2000-2002 GPRs do not have the 2" extension, but the 2002 has a shorter drive shaft for some reason. The year 2002 GP12R will NOT require intermmediate shaft, but will instead require the longer driveshaft.
So to put this easier - 2002 and down do not have the 2" extention.
2002 has the correct intermediatte shaft, but a shorter driveshaft.
2000-2002 were 1200cc's w/85mm pumps and with powervalves / but no 2'' extention
2003-2004 were 1300cc's w/85mm pumps and with powervalves (165hp) / with the 2'' extention / with lighter (SMC) hulls than 00-02.
2005-2006 are 1300cc's w/87mm pumps and no powervalves (170hp) / with the 2'' extention / with lighter hulls than all models before.

What benefits can be expected by changing to the high pressure pump?
I was under the impression that at some point they increased the driveshaft size also. Was this with the increased hub diameter in the 2005-2006 models?
I have a 2002 with the 2" extension added and an 87mm reduction nozzle.

So if I understand this I can use my existing driveshaft acquire an 05-06 pump with cone and swap out the internals? New prop would be to accomadate the benfits of the pump?
