Our Services & Offers


Annual tune-up services include all the necessary manufactures required maintenance to ensure your watercraft will run at optimal performance, extending the life of your craft.



Watercraft tune-ups are recommended after every 30 hours of riding time. Service includes changing or cleaning the fuel filter, replacing spark plugs, engine compression testing, carburetor adjustment, filling the oil tank, greasing zerk fittings, grease PTO (Power Take Off), changing pump fluid (Sea-Doo models), adjusting and lubing all cables, tightening nuts, bolts, and clamps.



Did you know that elevation affects the performance of your personal watercraft? If you want the highest levels of efficiency and speed from your jet ski, a carb tuning is highly recommended before operating your watercraft at higher elevations.



Jet Ski Carburetor rebuilds for personal watercraft vary depending on the application. Kit charges and replacement parts will apply.



PWC’s are required to have the jet pump serviced on a regular basis. Sea-Doo jet pumps have a sealed, oil-filled impeller shaft which requires an oil change every 30 to 50 hours. Failure to have this service performed regularly results in costly watercraft repairs.



Hydrostatic lock, hydraulic lock, or hydro lock occurs when liquids, typically water, enter an engine cylinder. You can hydro lock a jet ski engine by flipping or sinking a machine in the waters and then cranking the engine several times trying to start the engine. This process will bring water up the exhaust system filling the crankcase with water. Because water does not compress, the engine becomes locked up. 

The best way to remove a hydro lock is to take your PWC to our qualified watercraft repair service center in Rialto to have it properly removed. If not handled properly, water ingestion will cause internal corrosion which results in premature personal watercraft engine failure.



Major engine rebuilds are available for all personal watercraft. There is no guesswork performed here, everything is tested in our in-house testing facilities.



Repairs and diagnosis are available for all PWC make and models in our watercraft repair shop located in Rialto, California. Downtime varies depending on the availability of parts.

JV Motorsports can service, repair, and maintain most makes & models of motorcycles, ATVs, UTVs & other powersport vehicles.
