My building of a GPRXP
I am taking a 2003 GPR and putting a 2005 RXP motor in it. As most of you know I have totally parted out the the GPR stuff I wont be using. I have almost sold everything from the GPR and the RXP. Below is some pictures of the conversion so far. I will keep posting on how and what I am doing.
Huge thanks the Mark (hydrotoys), Jerry (Green Hulk) Joe (insandeigo rxp), Abbott, Rapid Acceleration, and Lawracing.

As of right now here is what is done:
RXP tank is installed and filler hose is modified.
took the stock RXP hose cut it in 1/2 put a 2"od piece of metal pipe in there and clamped it. Took the RXP straps and brackets and rivited them to the innerliner and strapped them like they were in the RXP (thanks Hydrotoys)
Pump is installed
I am using a 2003 pump GPR. transom plate water passage has been opened up to 5/8. (thanks Hydrotoys).
Ride Plate installed trim tabs too
R/D ride plate angle modified. They were in the ski from the past project.
Painted CF fairings, gas cap, sponcens, hood, and grabbar
Old School Customs 205 966 2238 Louis
Modified inner liner
A most to get the motor to fit low enough to get the drive shaft to line up. Aslo removed the center brace. Filled anywhere it is possible for water to get between the layers with 5200 or silcone.
Dirt bike handle bars
I like the look and feel of them better than stockers (thanks Abbott)
Mode SET Stop/Start switches and guages
I installed the switches on the dash I used the stock RXP switches but cut into the dash to make thm sit flush. I had to make a plate to hold them in place but I thnk it looks sweet. the guages I used the RXp guages in the hole where the GPR guages were. I had to grid out the panel to make the guages fit. I have also installed an Autometer Boost guage where the old oil filler was. I have installed an Autometer guage for water PSI where the old fuel selector would have been.
Mounted the MPEM up in the nose on a flat plate useing the RXP bracket. It is where on the 03 GPR brain was mounted.
Mounted the battery/Battery Box
Took the RXP battery Box cut down the spacers and used the GPR battery. The GPR Battery is smaller and lighter. One side of the box is bolted to the boss where the center bease used to be, and the other side id bolted to the false boss right behind the center suppoert was. I know for a fact the GPR battery is strong enough to run the RXP due to the fact I lent it to a guy in Jacksonville for the weekend to use in his RXp that had a bad battery so he could enjoy the weekned and not have to run out Saturday morning and buy and miss all the fun.
Mounted and wired the DESS key
I mounted it in the center of the glove box lid. I copied Hydrotoys design. (thanks Hydrotoys)
Motor was sent off to NILS for rebuild
The ski I bought to steal the parts from had a motor that was locked up for saltwater intrusion. The stock intercooler was leaking.
Mats have been removed from the top deck
I am going to install Hydroturf after it gets a fresh cot of paint. As of right not I am undecided on the paint color. I usually paint everything I own Black.
Bitchin Stiches seat cover installed.
I bought this seat cover used from Hydrotoys its black and silver I will get pictures up asap (thanks Hydrotoys)
I will post more as things get finished

One problem with the MPM being mounted there is clearance to the front bucket. I'm pretty sure once you put the wiring on, you won't be able to put the bucket in without rubbing, constantly.
You could take the handy heat-gun, and bend the bucket away from the assembly, once you hook up the wiring??? Or run without it, as some do. I don't recommend it except for super flat, smooth water. Even then, the GPR does get lots of water over the hood in turns
Possibly chop the bottom off that bracket, which would sit it lower, and maybe out of the way of the bucket.

As I get time, I'm putting up the basic instructions on the conversions on the following section over at hydrotoys, mainly to keep it in one place.

See what you started? I love it.

Just one ride, and it's tough to get the sensation of speed, smoothness, turning ability, midrange punch and repeatability out of your mind. It sounds pretty cool too. I am simply amazed how easy it turns now, compared to the 2stroke. The powerband doesn't lurch you...it just keeps coming around. The bottom end hit is way too much for the poor GP800r grate. It burns that puppy off. You must apply the throttle...not just choke it's neck. I can't wait to get one in a full-on handling setup, and not these bouncy, bouncy smooth water speed setup.

Mark my paln was to take a heat gun to the bucket to make the wiring work around the bucket its close just like everything else. My second idea was to cut the bucket down and plastic weld it back together.
