WATERCRAFT SEASON! QSM is the Inland Empire’s premiere watercraft one-stop shop! From parts to service and everything in between we can help you out! Don't take your ski to a bike shop that claims to "know" how to work on watercraft. QSM has the experience to get your watercraft running right so you can enjoy your vacation. 


QSM specializes in the following brands:



KEY PROGRAMMING- We can program all your Seadoo, Yamaha, and Kawasaki coded watercraft keys.

DIAGNOSIS- QSM can diagnose even the most complex problems. Many times, a watercraft will run perfectly until you put it in the water and start riding. This can be very frustrating and a very difficult diagnostic. With over 25 years of experience, QSM's service department can figure it out the first time. 


BATTERIES - QSM offers free battery installation with the purchase of a new battery from us. Also, you will not find a more competitive battery price. Please call for price and brand options available.

Two stroke watercraft myth: (taken from)




Two-Stroke Vessel Engines Facts About Two-Stroke Vessel Engines Two-stroke engines are not "banned" for use on all waterways in California, nor is there any plan to do so. Carbureted and electronic-injection two-stroke engines are considered high-emission engines. Generally, these engines were manufactured prior to 1999. A carbureted two-stroke engine can emit up to 25-30 percent of

its fuel unburned into the water or atmosphere, which is why high-emission engines are prohibited on some lakes. There are no salt-water or river restrictions in California on high-emission

two-stroke engines, excluding personal watercraft (vessels such as Jet Skis) bans in some areas. For example, San Francisco has prohibited personal watercraft within 1200 feet of its shoreline. See

"Local Restrictions" on our Web page for a list of lakes. Direct injection two-stroke engines, made since 1999, are considered clean emission engines and can be used on every water body in

California, with some exceptions not related to emission limits. A new direct injection two-stroke engine will normally have a label sticker (with 1 to 3 stars) on its engine cover indicating that it meets California Air Resources Board emission regulations for 2001, 2004, and 2008 for vessel engine manufacturers:
