The coolant MUST BE propylene glycol coolant ONLY.Never use ethylene glycol or Dex-Cool, nor ever attempt tomix coolants as they will not properly mix. Use of unapprovedcoolant will void the warranty.Inspect the Sea StrainerRaw water from the lake/river/sea is drawn into the boat as partof the cooling system for the engine and drive train. Even with theclosed cooling systems, it is necessary to circulate additional wateras part of an effective cooling system. To protect the system, a seastrainer is installed near the raw water intake, aft of the engine nearthe steering system’s tiller arm. The sea strainer serves the purposeof keeping debris from entering the raw water cooling system andcausing eventual engine failure. As with any kind of strainer, it isnecessary to regularly clean it so that water can flow unimpeded.When operating the boat in “dirty” water that is brackish or hasa noticeable degree of weeds and other flora, it may be necessaryto clean out the strainer in boats equipped with sea strainers evenduring an outing. Pay close attention to the engine temperature,which appears on a gauge or video screen. (See the Dashes andVideo Screens section of this Owner’s Manual for more information.)An overheating engine is probably due to inadequate water flow.Continuing to operate aboat that is overheatingthe engine and drive trainwill result in engine failureeventually. Boat operators should routinely review theengine temperature information provided on the gauge orvideo screen on the instrument panel. Ignoring or failingto take proper steps to reduce the engine temperature,resulting in damage, is not covered under the warranty.Leave the engine OFF.To inspect the sea strainer, open the engine compartment.Note the sea strainer’s appearance as shown in the accompanyingphoto. (If you cannot locate the sea strainer, ask for assistance fromyour authorized Malibu dealer. This step is critical and cannot beoverlooked. Also shown in the photo is the adjacent optional flush kit,which does not require normal consumer maintenance.)Open and lift the cover to expose the filter.Remove the filter and examine for any debris that hasaccumulated within it. When necessary, clean out the filter and thenreinstall it in the housing. Hand tighten the lid so that water will notleak out and into the engine compartment.If it is necessary to check the sea strainer during an outing, turnOFF the engine first and then close the valve on the water pickupfeeding the sea strainer. Make sure you open the valve prior torunning the engine; otherwise, it will overheat. Whenever the engineis running, water is being drawn in and you will not be able to inspectthe sea strainer.Check the Battery Holdersand the ConnectionsBecause batteries contain fluid that is caustic and potentiallydangerous to skin and body parts, boat operators need to ensure thatthe batteries are securely in place. Also, if the connections are loose,erroneous readings may be sent to the boat system, which can causerunning and functionality problems. To avoid becoming strandedduring an outing, it is important to have accurate voltage readingshttps://www.boat-manuals.com/
