HOW TO UPGRADE THE GP1200R WITH THE 2'' EXTENSION.
Here is a parts list, with various pictures. You will need to extend your trim and throttle cables as well.
60E-51317-00-94 HOUSING, IMPELLER2 ONE **Actual spacer.
99590-14016-00 PIN, DOWEL TWO **Locates spacer to B-plate.
90119-06859-00 BOLT, WITH WASHER ONE **Small bolt on left side.
90119-10803-00 BOLT, WITH WASHER FOUR**Longer bolts that mount spacer plate AND wear ring to B-plate
68N-51323-00-00 SHAFT, COUPLER ONE **This part is the intermediate shaft.
F1G-61481-02-00 CABLE, STEERING ONE **This part is over $200!! You can make a cheap extention instead!
68N-45593-00-94 FLANGE, COUPLING ONE **This is the coupler on the intermediate shaft.
90201-248M5-00 WASHER,PLATE ONE **This is the washer behind coupler.
Note: The year 2002 GP12R will NOT require intermmediate shaft, but will instead require the longer driveshaft.
66V-45511-00-00 SHAFT, DRIVE ONE
NOTE: All years of GP1200R will require some type minor grinding to original or aftermarket 1200 rideplate and pump housing.

I am thinking about doing this with a HO Pump on my GP1200R.
Do you have any installation instructions (How does the coupler shaft go in)?
Do you have any pics/diagrams/how-to's on how to extent the cables?

well, it's said to be about 1-2 mph. and then the 05 pump is about another 2 mph. go with the 05 pump and 2 inch spacer and u looking at 2-3 mph on top end and better hook-up

Mark, will you touch base again on which GPR (Year model) that does not have the 2in extention already on it? I think RX talked about it in his thread about this as well.

2002 and down do not have the 2" extention.
2002 has the correct intermediatte shaft, but a shorter driveshaft.

I think that the actual extension may slow you down. The gains are from the new pump vein housing.

6 months ago, all I heard was that you HAD to have it to keep the ski hooked up.
Kerry told me this directly over the phone.
