300 miles is a long way .
World’s Longest Continuous PWC Race Set for February 24th DSM Events owner, Jim Russell and Mike Follmer, event co-promoters, announced today that the 2007 – Mark Hahn Memorial, 300 Mile Endurance Race is all set to launch on February 24, 2006 from Crazy Beach at Crazy Horse Campground in Lake Havasu, Arizona. The event will once again be sanctioned by the American Power Boat Association (APBA), and it is expected that a very large number of teams will enter to try and break the APBA Endurance Record of 4 Hours 50 Minutes to cover the 300 miles set at last year’s event by Steve Friebe and Matt Legerski aboard their 4 stroke Sea Doo RXT. The Jet Ski race is being held again in the memory of endurance racer Mark Hahn who was instrumental in providing the momentum to keep Jet Ski endurance racing going strong and growing across the country before his untimely death. The “Team” format features two riders for runabout (sit down) boat teams and up to three riders for a stand-up craft. Solo riders are also welcome to “Ironman” the race on either style of PWC, a real test of endurance and stamina reserved for only the true endurance zealots. The race is being held at Crazy Beach at Crazy Horse Campground that has undergone some massive reconstruction at the hands of Jim Russell over the last several months. “This is now a “World Class” site for this very important event”, said Jim Russell, “and the 7.5 mile course we have approval from the Coast Guard for will pit all the teams against the wind, rough water and long runs that this event has become synonymous with.” In addition to all the weather and water conditions all the teams have to contend with, they will also be required to make fuel stops without spilling fuel and make rider changes several times during the race. After the gigantic success and world wide recognition received in the press of last year’s Mark Hahn Memorial, it is expected that this year’s entries will far surpass the 60 teams that were there for the last years event. Mike Follmer said, “We’re gearing up to make this year’s event outshine what we did last year by getting more give a ways and even better trophies for the massive awards banquet we have already scheduled.” “We have on the water still photography to chronicle the event for the riders and magazine coverage and are in the final throes of securing television coverage by tv 45 in Havasu. Follmer added. All of the pre-race attention and planning for this year’s Mark Hahn Memorial guarantee that it will be even better than the inaugural, which has been heralded as the “Best PWC race of the year”! Get your teams together and your entry in early to make sure you don’t miss out on this great experience. Entry forms and entry information sheets were released today for the February 25th event. This race is an APBA Sanctioned event and as such, ALL riders MUST be an APBA Racing Member. If you are not now but want to become an APBA Racing Member, please call Patrick Mell at (586) 773-9700 or go online at www.apbaracing.com to sign up. www.pwcfun.com/markhahn300.asp The Mark Hahn Memorial Havasu 300 Team Race is a stand alone event to honor our fallen friend Mark Hahn. It is not part of the annual point race and therefore there will be Six (6) classes only, as listed on the entry form. Get your team set and your entry in early to avoid the $25.00 late fee if your entry is not received by DSM one (1) week prior to the race. DSM will accept VISA, MASTERCARD or a check for the entry fee to make payment very easy. If anyone has a problem with this entry system or wants to make special arrangements, please contact Jim Russell at DSM immediately at (928) 764-2210 in an effort to limit the confusion on race day and insure that the race gets started exactly on time. All entrants MUST have eight inch (8”) black number(s) on a white background to be scored. Numbers will NOT be available at the race site on race day. Awards will be for First through Tenth in the Overall order and First through Third in each Class. The awards are really special for this event, AND there is a growing pile of merchandise that has been donated by friends and supporters of Mark Hahn that will be doled out to make sure that EVERYONE who competes receives something to take home as a memento to remember this great event! The AWARDS will be at London bridge resort same as last years event starting at 7.30 pm.

2007 KAWASAKI JET SKI ®ULTRA® 250X
Staff Kawasaki stunned the motorcycling world with the launch of its Ninja ®ZX-14 flagship. It didn’t take long for the mighty ZX-14 to assume its rightful place as the quickest and fastest stock production motorcycle. Now, Kawasaki extends its high-performance domination into the realm of personal watercraft. As the quickest and most powerful production PWC in history, Kawasaki’s new JET SKI® Ultra® 250X serves notice that “ULTRA” defines the pinnacle of PWC performance. The supercharged Ultra 250X delivers 250 horsepower for astonishing acceleration that can be felt in the rider’s soul. Once up to speed, its precise handling and superb stability are equally impressive, thanks to a brand-new hull specifically designed to capitalize on the engine’s awesome performance. The JET SKI Ultra 250X’s new engine, jet drive and hull incorporate racing technology refined through Kawasaki’s multiple IJSBA championships. This same technology allows it to deliver the awesome acceleration of a drag racer, and help ensure excellent hook-up – even in rough water. With a 1,498cc marine engine derived from Kawasaki’s astounding JET SKI STX®-15F watercraft, the Ultra 250X produces power comparable to a normally aspirated high-performance three-litre engine, thanks to the addition of a Roots-type supercharger. Unlike centrifugal superchargers or turbochargers, the Ultra 250X’s high-volume direct-drive supercharger delivers boost virtually instantly at any engine speed from idle to redline. This results in a linear, smooth torque curve which is ideal for a personal watercraft that needs to accelerate hard all the way from a standstill through astounding top-end speeds. A common drawback of forced-induction is the heat build-up that occurs when the intake air is compressed. The Ultra 250X overcomes this with the use of a large-capacity intercooler. The 250X’s supercharger compresses the air to a maximum boost pressure of 11.4psi. This compression heats the intake charge to extremely-high temperatures, which could limit the engine’s power output. However, the 250X’s large-capacity intercooler cools the intake charge back down to ambient temperature or even less – ideal for producing maximum power. The JET SKI Ultra 250X’s stunning acceleration is augmented by a huge 155mm jet pump featuring the largest PWC impeller and nozzle Kawasaki has ever produced. Developed based on feedback from Kawasaki’s race machines, this pump was specially designed to deliver predictable thrust and good “traction,” even when riding on rough water. The pump uses eight guide vanes (instead of the six used on previous models) to regulate the flow of water from the impeller for efficient and powerful propulsion. This is a significant factor in the Ultra 250X’s mind-boggling acceleration. The new pump incorporates a groove from the center to the rear of the ride plate which makes it easier to hold a stable heading when riding in a straight line. To suit the 155mm jet pump a new, larger impeller was designed, offering improved “bite” in the higher speed ranges. The sophisticated three-blade design not only delivers high performance, but also provides smooth and quiet operation. In addition to more power and acceleration than any other production watercraft on the planet, the Ultra 250X also boasts an all-new race-developed hull. Extensive research and refinement has allowed Kawasaki to design a brand-new hull which is just as comfortable in rough conditions as in calm. Even at high speeds, rough water can do little to deter the Ultra 250X. This combination of unearthly power mated to the latest hull technology allows Kawasaki’s flagship to literally cleave through waves that would send lesser machines running for safe harbor. In addition to its acceleration and top-speed capabilities, the Ultra 250X also offers precise handling and superb stability, thanks to a hull that was specifically designed to compliment the engine’s incredible output. This fiberglass reinforced plastic (FRP) hull is loaded with DNA from Kawasaki’s IJSBA championship winning machines. This includes carefully designed sponsons and chines for enhanced straight-line stability and precise cornering, combined with a 22.5° deep-V hull for a smoother ride in rough water. In recognition of the tremendous power on tap, Kawasaki designed the Ultra 250X’s hull to lean into corners like a motorcycle. This helps passengers stay centered, and keeps the rider in control during peak cornering g-forces. The Ultra 250X features a five-step adjustable handlebar position that allows either stand-up or sit-down riding for enhanced comfort and versatility. As Kawasaki’s flagship watercraft, the 250X includes thoughtful standard features like an enormous 53 gallon detachable front storage compartment and a 20.6 gallon fuel tank (the largest in its category) for substantial cruising range. From horsepower to handling and everything in between, once the spray settles after the first ride, one thing will be certain. As the most powerful PWC on the planet, this “ultra” new JET SKI offers performance and excitement that are unmatched by any other watercraft. 2007 JET SKI ®Ultra® 250X Features and Benefits Engine − Liquid-cooled 1,498cc, in-line four-cylinder engine is fitted with a supercharger and intercooler − Most powerful production PWC engine in the world − The 83.0 x 69.2mm bore and stroke are the same as the JET SKI STX®-15F’s powerplant − Compression ratio is lowered to 7.8:1, to minimize detonation at high-boost pressures − Inconel exhaust valves are fitted for superior heat resistance and enhanced reliability (Valve sizes are: 33.4mm intake / 28.3mm exhaust) − The engine’s over-rev capability has been raised by 700 rpm (redline is 8,900 rpm) − Precise power adjustments are easy with a throttle lever that is designed to prevent finger fatigue on longer rides Roots Type Supercharger − The Roots type supercharger design produces large amounts of boost even at low rpm, for instant and powerful acceleration right off of idle − Force-feeds the engine two liters of air with every revolution, providing a stable supply of high-pressure intake air at all rpm − Provides a very flat and meaty torque curve with step-free power across the rev range and none of the lag associated with turbochargers − Produces a maximum of 11.4psi of boost pressure − Produces more low RPM boost than competitive or aftermarket systems − To prevent over boosting at low and medium rpm, two different air bypass valves (ABV) are used − The smaller ABV releases low amounts of excess pressure build-up, for precise boost management − The larger ABV is used when excessive boost pressure is accumulated, to maintain an even intake pressure even when giving full-throttle from idle Air-to-Water Intercooler − Efficiently cools the high-pressure intake air − Cooler air results in higher combustion efficiency and high engine output − Liquid-cooling allows the intercooler to maintain consistent thermal performance Fuel Injection − New, high-flow fuel injectors with four orifices are fitted to complement the increased power output and improve combustion efficiency − Single throttle body features a large 60mm bore diameter Exhaust − The Ultra 250X features a 4-into-2-into-1 powerboat-style exhaust system, which routes the exhaust pipe upwards. − Allows the smoothest path for exhaust gases, maximizing exhaust efficiency Jet Pump − To efficiently convert the Ultra 250X’s massive horsepower into thrust, an all-new, large-diameter 155mm jet pump was designed − Developed based on feedback from Kawasaki’s race machines, this pump was specially designed to deliver stable output and good “bite,” even when riding on rough water − The reverse lever has been moved from the right side to the left side for easier operation Impeller − To suit the new 155mm jet pump, a larger impeller was designed, offering improved thrust in the higher speed ranges − The sophisticated three-blade unit delivers both high performance and quiet operation Guide Vanes − To suit the new jet pump, a new eight-vane intake guide is used. These guide vanes smooth and regulate the flow of water from the impeller for efficient and powerful propulsion − Eight guide vanes provide superior “traction” compared to the older six-vane system Ride Plate − Features a groove from the center to the rear of the ride plate, to enhance straight-line stability Hull − The new hull was designed based on feedback from Kawasaki’s IJSBA championship winning racing machines. − Specially designed to cope with the engine’s horsepower − Offers a combination of high stability and responsive handling in both calm and rough-water conditions − Delivers the neutral handling and turning characteristics that made Kawasaki JET SKI watercraft famous − The new super-strong hull is 250mm longer, to ensure stable handling performance with the larger, more powerful engine − The lower hull is specially designed to distribute the engine and power delivery loads over a wide area − Although it has a similar V-shape to the JET SKI STX-15F, the Ultra 250X’s hull enables a high bank angle, for motorcycle-like turning performance. This reduces the side G-loads imposed on riders during turns − The V-angle at the bottom of the hull has been changed to 22.5° to help prevent spinouts during sharp turns and to provide a smoother ride in rough water − To avoid concentrating heavy components towards the rear, the battery is located inside the front storage area near the center of the machine. This remote location also frees up space inside the engine bay Bond Flange & Bumper − The bottom of the hull slants upwards steeply from the center section to the bow, allowing the Ultra 250X to penetrate swells and waves with less shock. At low speeds the result is extreme stability; at higher speeds the Ultra 250X’s massive thrust enables the hull to push through waves rather than bounce over top of them Sponsons − Newly developed sponsons extend further from the hull, providing stable straight-line performance while helping to retain the narrow hull design. They also contribute significantly to the Ultra 250X’s excellent maneuverability when changing direction (particularly at higher speeds) Quattro KSD − Ridges across the bottom of the bow, Kawasaki Splash Deflectors deflect water splashing forward from under the hull. To reduce spray during high-speed turns, the earlier triple splash deflector now has one more deflector mounted at the top. Whether turning or blasting straight ahead, at high speeds or low, the Quattro KSD minimizes spray, allowing greater rider concentration and a drier ride Kawasaki Smart Steering®/SLO-Mode − Kawasaki Smart Steering (KSS®) is equipped to help new riders better enjoy the performance of this remarkable machine − Smart Learning Operation (SLO)-Mode function allows newer riders to become familiar with the handling and response of this JET SKI watercraft at a more relaxed pace before unleashing the full power of the Ultra 250X. Two separate keys (one for SLO-mode, one for full-power operation) help prevent confusion over which setting is in use Comfort and Convenience − Five-way adjustable handlebars allow operation while standing or sitting and are designed to suit a wide range of riders. − Relatively narrow seat is comfortable for either stand-up or seated riding, or when riding with passengers − Ergonomic deck design gives plenty of legroom without necessitating a high seat, for rider-friendly seating accommodations − A long rear boarding step makes it easy to climb on board, and the step retracts inside the bumper to prevent damage − A quick and easy under hood hose connection allows nearly silent cleaning system to flush sea water out of the engine − Mirrors are mounted to the upper deck to facilitate opening of the hatch cover Capacious Storage − The large-capacity, fully sealed 53 gallon storage area has plenty of room for recreational equipment. A detachable storage tray is also fitted − Mounted on the center console is a detachable drink holder with space for two drink bottles − A compact storage area is integrated with the under-seat rear grip and ideal for small items Increased Fuel Capacity − Offering more fuel capacity than any machine in its class, the Ultra 250X’s 20.6 gallon fuel tank holds 3.7 gallons more than the JET SKI STX-15F watercraft 2007 JET SKI® Ultra® 250X Specifications* Engine: Four-stroke, DOHC, four valve per cylinder, inline four-cylinder Displacement: 1,498cc Bore x stroke: 83.0 x 69.2mm Compression ratio: 7.8:1 Induction system Roots-type supercharger with air-to-water intercooler Maximum boost: 11.4 psi Maximum horsepower 250hp @ 7,750 rpm Cooling system: Inducted water Fuel system: Digital fuel injection Ignition: TCBI with digital advance Starting: Electric Lubrication: Semi-dry sump system Coupling: Direct drive from engine Propulsion system: 155mm jet pump, axial-flow, single stage Impeller: Three-blade, oval-edge stainless steel Thrust: 1,524 lbs Seating capacity: Three-person Load capacity: TBD Fuel capacity: 20.6 gal Oil capacity: TBD Storage capacity: 53 gal Dry weight: 903.8 lbs Overall length: 132.7 in Overall width: 46.9 in Overall height: 45.3 in Colors: Sunbeam Red / Sunbeam Red Valiant Blue / Metallic Phantom Silver MSRP: TBA Kawasaki Motors Corp., U.S.A.
