jPREVENT MAJOR DAMAGE 29 Drain the Exhaust System To prevent major engine damage and to help prolong the life of the exhaust filter, you must perform the following procedure to expel excess water from the exhaust system. This helps prevent premature wear due to internal engine corrosion and the build up of salt or other mineral deposits that can lead to cooling system blockage and overheating. After each use in fresh water, remove the watercraft from the water. Start the engine and run it for several seconds to purge the exhaust system of excess water. Rev the engine repeatedly, until water stops coming out of the exhaust at the stern. Jet Pump and Seals Periodic Maintenance • • • NOTICE To prevent overheating resulting in engine and exhaust system damage, do not run the engine with the watercraft out of the water for more than 15 seconds at a time. Never operate the engine at maximum speed out of the water. each use in salt water, flush the cooling • After system with fresh water (see the Cooling System Flushing section in the MAINTENANCE AND ADJUSTMENTS chapter). The jet pump bearings and seals require periodic service. Major engine damage can occur if the jet pump bearings fail due to lack of maintenance. Have your Kawasaki dealer inspect the jet pump bearings and seals after the first 25 hours of use or after one year, whichever comes first; and then every 50 hours or every year, whichever comes first. The jet pump bearings should also be serviced before any prolonged storage to prevent any water that may be left in the pump from corroding the bearings and causing premature failure. j
