Hope you are correct about the weight of the kawi ski. I really don't want a 900+ lb ski much less 2 of them.

Availability?
March? April?

Hopefully March but with my luck it will be like late April/May timeframe

800-900 lbs....

Hey Orlando; Kawi would never put a "4tec" in ANY of their skis because that is a Sea-doo engine...you must have meant to say a "4 STROKE"

Richard

Yes you are correct. I am speaking of 4-Stroke. Ill correct it now, dont want to drop the market value of Kawi.

Those pictures on my shutterfly site are a little hard to read. Sorry I couldn't upload the bigger pictures.

Here is some better info....in pdf format with big pictures and stuff. So download it before the link disapears... this other guy can't host it too long.

[0044] A supercharger 41 is connected to a lower portion of the intercooler 40. More specifically, the supercharger 41 is positioned in the vicinity of a lower portion of the air-intake ports 37 of the engine E and above the crankshaft 9 in this embodiment. In this structure, the air flows from the supercharger 41 to the air-intake ports 37 through relatively short air-intake passages. The supercharger 41 is of any of mechanically driven types, including the Roots blower type and Lysholm compressor type. In FIG. 3, the supercharger 41 of the Roots blower type is shown. As shown in FIG. 4, an air-intake box 42 is disposed behind the engine E. The supercharger 41 and the air-intake box 42 communicate with each other through an air-intake duct 43.

[0012] The personal watercraft equipped with the mechanically driven supercharger, such as Roots blower type supercharger or Lysholm compressor type supercharger, can improve operation while ensuring high power output from the engine, since delay in the response to the rider's throttle operation is less likely to occur.

Correct me if I am wrong but I see TWO DIFFERENT diagrams for a supercharger setup in that pdf! The one on page 8 is a supercharger driven from the cam direct to the supercharger and the second one which is on page 4 is a supercharger driven from what looks to be the driveshaft coupler to a supercharger that has a clutch pulley on it. Wonder which one they will actually be producing??

Keith,

The picture your looking at on Page 4 is the clutch setup. It's kinda looks like the AC compressor..lol... It really looks simular to the clutch setup Toyota used on the superchargers they put on the MR2. If you read the discriptions they claim it's a cam driven supercharger and explain this.

Yeah but in one picture the sc is driven from the cam in the other picture it is driven from the coupler...

Maybe this might help...

[0016] The supercharger may have a rotor shaft configured to be coupled rotatably in association with a crankshaft of the engine by a pulley mounted on the rotor shaft and a pulley mounted on an output end portion of the crankshaft.

[0015] The supercharger may have a rotor shaft configured to be coupled rotatably in association with a camshaft provided in a cylinder head of the engine. The supercharger is mounted in the vicinity of the air-intake ports to be relatively distant from the crankshaft and closer to the cylinder head. In this construction, the camshaft may be coupled rotatably in association with the rotor shaft of the supercharger through a belt or a chain, or by a gear train of gears mounted on these shafts.

[0045] The supercharger 41 is configured to house a rotor (not shown) within a housing 45. The rotor is configured to rotate with a rotor shaft 46. As shown in FIG. 4, the rotor shaft 46 protrudes rearward outside the housing 45 to extend in parallel with the crankshaft 9. A first pulley 47 is mounted on a rear end portion of the rotor shaft 46. A second pulley 48 is integrally and rotatably mounted on a portion of the crankshaft 9 protruding rearward outside the crankcase 30 and located in front of a coupling means 10. The rotation of the second pulley 48 is transmitted to the first pulley 47 through a belt 49.

[0046] In the air-intake system 50, the crankshaft 9 of the engine E rotates to cause the supercharger 41 to be driven.

[0066] A driving rotor 85 and a driven rotor 86 are housed on the left side and the right side within the housing 81, i.e., the first chamber 76a. The driving rotor 85 and the driven rotor 86 are mounted to rotor shafts 87 and 88 with center axes oriented in the longitudinal direction of the body 1. As shown in FIG. 7, the rotor shaft 87 to which the driving rotor 85 is mounted has a rear end portion protruding rearward from the housing 80, and a first pulley 90 is mounted on the rear end portion of the rotor shaft 87. A rear end portion of a camshaft 91 on the air-intake port side which is housed in the head cover 33 of the engine E1 protrudes rearward from the head cover 33 and a second pulley 92 is mounted on the rear end portion of the camshaft 91. A belt 93 is installed around the first and the second pulleys 90 and 92 to connect them. In this embodiment, the first pulley 90 has a diameter half as large as that of the second pulley 92.

[0067] In the personal watercraft constructed as described above, when the engine El drives to cause the camshaft 91 to rotate, the rotation of the camshaft 91 is transmitted to the rotor shaft 87 via the first and second pulleys 90 and 92 and the belt 93 such that the number of rotations of the rotor shaft 87 becomes twice as many as that of the camshaft 91, thereby causing the driving rotor 85 and the driven rotor 86 to rotate. As a result, the taken-in air drawn into the housing 81 through the air-intake inlet 83 is supercharged by the driving rotor 85 and the driven rotor 86 within the housing 81, and the resulting supercharged air is sent out under pressure from the air-intake outlet 84 of the supercharger 80 to the air-intake ports 37, through which the air is supplied to the combustion chamber of the engine E1. The first pulley 90 may be configured to be driven by the pulley mounted on the crankshaft 9 as shown in FIG. 3.

That last one put us all to sleep. Its like ready the instuction to putting together a garage door opener..

hopefully someone can sneak some pictures or video and post it up here. That would be sweet.

Yeah well there's no SC ski on the Kawasaki press kit (yellow SXR, yellow STX900, red 12F and green 15F).

So unless it's a late release (don't dream) or even better an unwarrantied short run of race skis (unlikely) guess we'll just have to wait another year.

Or two
Or three
Or four

or whatever...

from what i hear, it is a 2007 release. Looks like Kawi blew it for 06......

I don't think they blew it.........they will however be competing with Yami's new release in 07.

It's war guys.....and the RXP started it all.

its a good call. it looks like the horsepower wars will be back in 2007. Im sure BRP has something up their sleeves as well to compete. should be an interesting year.

jeff.....you think by filing a patent in february is enough time to actually develop, test and mass produce the machine? i dont think thats nearly enough time. Just because they did the survey doesnt necessarily mean that its ready to roll for this year. If I recall correctly, didn't the reps that were giving the survey make mention to the point that the skis were no where near ready to be realeased and in the early stages of testing? like you said, this weekend is the telltale. I wouldnt be surprised to see the ski be realeased in short production as I believe 11 was saying. Lets wait till Saturday and see!!!

short production!!!!!,yes i remember they did the same thing with the 2002 stxr ,i put a deposite on one of those the day after the dealer show,
