It seems the old GPs are like a fine wine. As 2-stroke sit-down PWCs are not manufactured anymore, there will be fewer and fewer of them as time goes on. [links]
And finally, don’t forget that riding a GP is rather a solo activity.
Once you have some experience in riding and maintenance, you can consider switching it to a GP1200!
First, the hull and the top deck was completely redesigned from scratch. The new design was fresh, modern and more stylish compared to its predecessor. here
With this system you can raise or lower the bow of the WaveRunner, depending on its load and the environmental conditions. It’s a great feature to reduce porpoising, which the GP was prone to doing.
On one hand, they are still much cheaper and easier to handle compared to a boat, and if you want to own a legal 4-seater WaveRunner, the SUV 1200 is one of your few options. here
You may be wondering: Is the Yamaha SUV 1200 the largest personal watercraft ever made?
Power source? Surprisingly, you can find a 2-stroke, 3-cylinder, 1131cc engine under the seat, which produces only 135 HP. more
And finally, never miss the water test! [links]
The good news is you can still find 4-seater PWCs for sale, even if only used ones. One of them, the Yamaha SUV 1200 is the largest WaveRunner ever produced. It’s not just one of the longest personal watercrafts in history, but just like its competitor the Sea-Doo LRV, it offers legal rides for 4 people!
I set the Yamaha FX140 4 stroke engine and aligned it up with the interment shaft and marked the engine mount locations. The rear mounts are 2 inches forward from the original location. I cut out the mounting plates and run a tap through each threaded hole. I took a straight edge and marked a line along the original engine mount holes on the SUV on each side. Marked holes 2 inches forward on the rear mounts and the front marks I marked while the engine was sitting in the SUV hull. I cut out the inner hull with a side grinder with a cutting disk and with a chisel and a screwdriver I separated the engine mounting plates from the hull. I removed the fiberglass from in front of the original mounting location on the bottom of the inner hull so that the mounting plates would be flush with the underside of the inner hull. The left rear mounting plate was beveled where the other three were rectangle. The right front mounting plate I had to cut about 1 1/2 inch off the front and at an angle so that it would fit the inner hull shape. I used some 5200 adhesive on the top of the mounting plates and put the bolts in each plate and tighten them in place. I then cleaned the area and laid the fiberglass matting to make the inner hull complete again.

I have studied and measured the two pumps and intermediate shafts and have decided what I am going to do to install the 4 stroke Yamaha FX140 engine as for the pump end. There is a 2 inch difference between the two setups both being 2004 year models. more
The SUV pump has one impeller housing, this is where the wear ring is located. here
Here is a picture with the second impeller housing removed from the FX140 pump. The left is the FX and right is the SUV.
I have the engine and pump removed from the donor jet ski. I will do a little cleanup and change out all the hose clamps with SS ones on the 4 stroke engine. Then comes the painful part, Taking my SUV out of service and removing the newly rebuilt 1200 cc 2 stroke engine. I sure hope that everything goes well so the SUV will be back running soon.
