Propellers Your Nautique boat is equipped with a propeller best matched to its engine and boat combination. If you feel you are experiencing poor performance, contact your Nautique dealer. Care and selection of your propeller is very important to proper boat operation. 7-7 V-Drive Sec 7_2010.qxp:Naut Air Sec 7.qxd 7/22/09 1:49 PM Page 7-8 Section 7 NOTES 7-8 V-Drive Sec 8_2010.qxp:Naut Air Sec 8.qxd 7/22/09 1:47 PM Page 8-1 Section 8 Care and Maintenance This section describes how to care and maintain your Nautique boat. Periodic inspection and maintenance of items listed in this section is absolutely necessary. Winterization and some engine maintenance functions are best performed by your Nautique dealer. Some maintenance items that can be done by you or your dealer are listed below. We suggest that you familiarize yourself with these even if you have your dealer service your boat. General Maintenance 1. Read engine operator and maintenance manual very carefully. 2. Check for fuel line leaks every time you use the boat. 3. DO NOT start your engine if gasoline odor is present. Gasoline fumes are highly explosive. Before starting your engine, open the engine cover, inspect the engine compartment for gasoline fumes and operate the blower for at least four minutes. Run your blower when operating at slow speeds. If fuel vapors are present, do not start the engine. Check all hoses and fittings to determine the source of the vapor. Make the necessary adjustments or take the boat to your local dealer to eliminate the fuel vapor. Fumes accumulating in bilge area present a fire or explosion hazard which could causedeath or severe injury. Ventilate the engine compartment byrunning the blower for four minutes, especially after repairingor refueling and check for fuel spills or leaks. If you smellgasoline vapor or see liquid gasoline, DO NOT start theengine. ! 8-1 V-Drive Sec 8_2010.qxp:Naut Air Sec 8.qxd 7/22/09 1:47 PM Page 8-2 Section 8 4. When servicing the ignition switch or any wiring, always disconnect the battery cables from the battery. 5. Check for water circulation when the engine is running. Exhaust should contain steady flow of water. In closed cooling systems, make sure the coolant in the cooling system is at the proper level. Engine Intake Water Strainer Visually inspect the engine intake water strainer for debris before each use. To clean the strainer, close the engine intake water valve and unscrew the strainer bowl (A). DO NOT lose the rubber O-ring (B) that seals the bowl to the cap. Carefully remove the screen (C). RAW WATER STRAINER CORC0232 C B A CORC078 Clean debris from the bowl and screen and rinse parts in fresh water. Insert the screen, place the O-ring in the groove of the bowl and screw the bowl on hand tight. Be sure to open the water valve before starting the engine. 8-2 V-Drive Sec 8_2010.qxp:Naut Air Sec 8.qxd 7/22/09 1:47 PM Page 8-3 Care and Maintenance Some engines are equipped with a closed cooling system with a self- contained reservoir for engine coolant. Self-contained systems are equipped with a heat exchanger which uses raw water to cool the coolant. All raw water systems are equipped with a valve and strainer. Bilge Pumps Check your bilge pumps often to make sure they are operating efficiently. There are two bilge pumps: one is at the rear of the boat near the rudder and under the floor by the forward bulkhead located next to the fuel tank. To keep the pumps from getting clogged, remove any debris you find in the bilge. Wash the bilge with a good biodegradable household detergent or a bilge cleaner available at your Nautique dealer or a marine supply store. Rinse with water with your bilge pumps running. If your pumps seem to lag, remove the top of the pump from the base and check the impeller to make sure there is no debris inside. See your dealer if there is still a problem with the pumps. CE Bilge Discharge Filter Your boat may be equipped with a CE-compliant bilge discharge filter system that is designed to prevent oil-contaminated bilge from being discharged into the environment. One CE bilge filter is required for each bilge pump. The CE bilge filter is located below the deck, connected to the bilge discharge hose just before the hose connection to the deck outlet fitting. CE bilge discharge filter cartridge XOil™ replacement should be part of a regular maintenance program to prevent oily, contaminated bilge from passing through the deck outlet fitting into the environment. The period between cartridge replacements will depend on the condition of the bilge. Always replace the cartridge immediately after there has been a great amount of oil or other contaminants spilled into the bilge. 8-3 V-Drive Sec 8_2010.qxp:Naut Air Sec 8.qxd 7/22/09 1:47 PM Page 8-4 Section 8 Cartridge Replacement 1. Turn off power to the bilge pump. 2. Unscrew the filter bowl (A) by turning counterclockwise and pour any excess bilge water remaining in the bowl back into the bilge. 3. Remove the use...
