* After 50 hours of initial operation, switch to a high grade motor oil of the proper SAE spec for your engine. This step alone may double your engine service life.

* Replace exhaust risers and gaskets every 150 hours of engine use (if salt water cooled), or every 4 to 5 years.if fresh water cooled.

* Replace exhaust manifolds every 300 hours of use (if salt water cooled)), 500 hours if fresh water cooled.
  Riser and or manifold failures are the number one cause of engine failure due to water ingestion and corrosion.

* Use a fuel stabilizer to condition fuel for periods when the boat is not in use. This will keep your fuel system clean for a longer period of time..

* Replace your raw water pump every 50-100 hours or one a year, and check the housing for leaks and wear. Todays engines can't survive over heating. Cylinder head failure in GM based engines due to over heating is an epidemic. So keep your engine as cool as possible!

* Replace gear oil and or transmission oil every 100 hours. Inspect propeller shaft seals for wear, fishing line, etc. Perform service every 250 hous as required.

* Use Racor brand fuel filkter to filter your fuel and remove water. Check it every time before leaving the dock..

* Replace all pencil zincs in the engine every 50 to 100 hours.

* Use fuel stabilizer and bio control additives to prevent growth in your fuel tank.

* Use high quality fuel filters such as Racor or Dahl, and replace them every time you perform an oil change at 100 hour intervals.

* Having an oil pumpout manifold will make changing the oil easier and will assit in keeping your bilge clean

* If you experience slow cranking speeds when initially starting, check your battery cable and connections. If you flex them and they make a cranking noise, repalce them.

* Inspect propeller shafts, and engine mounts. If any vibration is noted while underway, do not operate the vessel any longerthan necessary with a bent shaft or propeller. This may cause severe damage to your trqansmission.
