Kawasaki Ultra 150 Modifications

Learn what is needed by this great PWC.

The Kawasaki Ultra 150 that was originally a very unpredictable jet ski became a tamed one with a few bolt on modifications. As we all know, the ultra 150 jet ski, was made a high performance rocket from factory and it took the speed title as the fastest stock personal watercraft produced and sold at that time. The handling modifications that follow made a big difference in sharp turning and the kind of water that you can ride in at full speed. They were and are well worth their cost and the effort involved.

There are many types of modifications already developed for the ultra 150 and the only limitations are, usually, the high price they will cost you. I have known of ultras that went over, a verified, 80 mph on radar or gps devices but, it took big $ in doing the modifications to get there. I know of a guy, Daren, that got his ultra 150, to run stable and reliable, up to 81.1 mph and then, he sold it because he had reached the hulls speed limit. That was his claim and I believed him since he documented the complete modification process, video taped the speed runs, and it can be viewed at a couple of related forums online. Some of the many types of modifications that you can do to PWC should include; handling, performance, safety, comfort and cosmetics. You could do them for recreational or circuit racing purposes. Most people that get involved with recreational performance modifications are going for raw top speed gains in order to beat somebody at their water hole. Circuit racers, on the other hand, are looking more for acceleration and handling combined with top speed.

Modifications cost will vary depending on "used versus new" and how good and lucky you get when looking for aftermarket parts. The best prices can be found searching on online at ebay and the many PWC forums that include classifieds sections, these seems to be the cheapest way. Be aware of the risk involved when buying online. I'm not related with any shop so, I can't control what the aftermarket parts will be selling for!

Which is the fastest PWC?

Well, nobody knows yet which one will be the faster jet ski in town but, no matters what brand of jet ski you ride, be it a Yamaha GPR, a Seadoo RXP or a Kawasaki Ultra 250X, nor if you live in the east, west coast or another country, I still like to wish all racing and recreational PWC enthusiasts lots of luck with their next modification and jet ski racing battle. God bless you all... Papoloko!
