Performed Recommended Maintenance Item
date/hours Interval

Engine
           Each sail date    Check engine oil level, coolant level, visual inspection for any fluids in the well; with engine operating check oil pressure,
                              coolant temperature and alternator voltage
           About every 25    Engine water strainer--Clean and remove debris
            hrs or each      Shaft Packing Gland--Depending on type installed, it should be visually inspected for excessive leaks
            time in engine     The standard gland should drip one drop every minute at rest and once every 15 seconds while in gear
             room            V belt--Inspect for hairline cracks, if find any, replace immediately. Buy a spare
                             Exhaust Riser--Look for corrosion,hairline cracks or water. Remove/inspect, probably replace, they last about 5 yrs

           150 hrs           Transmission Oil--Replace, most 4JH2E use same oil as engine
           300 hrs           Fuel Filters--Replace both, this is a great time to practice bleeding the fuel in case it needs to be done out at sea
           300 hrs           Valve Adjustment--Be sure engine is cool
           300 hrs           Water Pump Impeller--Replace, keep best looking one as a spare

          Zincs             Replace as needed
          Cutlass Bearing   Check for tightness by giving it a good shake. If it rattles, replace bearing
          Rudder            Should be less than 3/4" deflection at base of rudder
          Keel              Look for cracks or signs of looseness, may need to torque keel bolts*
