Outlaw, thanks for for the response.
OK.... so then what you would recommend to get the best performance (top speed) out of the 2002 Waverunner XLT 1200? Stage 2? Personally, paying the quoted cost of $2500 (includes labor) to get an additional 5mph, or maybe a tad more is somewhat laughable to me. In optimal conditions, I have had my waverunner to 63 speedo ~ (62 mph on Garmin GPS) ~ which for stock 155hp PWC weighing 780lbs (plus 200lbs for my weight) is pretty good top end speed.
I get the whole idea of the stress mechanically created on the internals of the waverunner (prop, etc) by adding nitrous, but yes, my goal is to achieve a short run at top speed while still having the waverunner for regular ole' weekend use.
I believe with the proper engineering and modifications, the engine (and other components) can handle the stress created by the addition of the nitrous. It is just a matter of understanding what will happen by adding nitrous and what components off the motor, etc need to be modified to handle the additional stress. This was the intention of my post. To gain some insight into those modifications needed.
Trust me, I am the type of person who puts thought into things and gains a full understanding of what it is I am attempting to accomplish and I have been putting a lot of thought and research into this project and was looking towards gaining some information from this forum by people who have either installed, had experience with or are currently using nitrous in their PWC.
My nephew has been working with nitrous for some time now with cars and motorcycles/drag bikes and I have their mechanics ready to install the nitrous kit for me, but I don't feel it is just that simple. I believe there are more mods to the engine that need to be done to support the install and that is what I was hoping to gain from members of this forum.
I appreciate your input and will invite others in this forum to reply with comments or suggestions as well.

Personally I think that a nitrous kit would be a total waste of money and time. I have drag raced snowmobiles for twenty years and never used or saw it used. What could you hope to accomplish? Any time you have an abrubt, temporary horsepower increase it can only be used in drag racing to try to get an edge in the short run. It would be hard to prop for it because of the horsepower differences. That is why they don't use nitrous on performance boats. Once you blow your load (tank) the party is over. Not to mention the engine will probably blowup.
I mean my fastest ski runs out at 75 MPH with just a supercharger kit. Don't get laughed at don't do it.
