Engine Break-In Procedure

Running the Break-In Procedure during the first 10 hours of operation will: 

  1. Improve overall engine performance. 
  2. Extend the life of your engine. 
  3. Prevent excessive oil consumption. 

The Engine Break-In Procedure

1. Preparing for Engine Break-In Procedure: 

  • Keep your engine in neutral. 
  • Start your engine. 
  • Run your engine for 5 minutes. 
  • Keep an eye on your Oil and Temperature gauges. 
  • Time your engine with a Timing Lamp to factory specifications. 
  • Continue running your engine for 45 minutes at 1500 rpm. 
  • Make sure your Oil and Temperature readings are OK. 
  • Note: this preparation can be done with your boat outside of the water. Make sure the water supply is hooked up correctly! 

2. Engine Break-In Procedure: The 10 Hour Sea Trial 

  • Safely run the engine with the boat in the water. 
  • Shift into gear. 
  • Advance the throttle above 1500 rpm. 
  • Vary the throttle every 15 minutes. 
  • Do NOT exceed 3/4 throttle during the first 10 hours. 
  • Check your exhaust manifolds and risers for any water leakage. 
  • Check for oil leaks around your engine. 

3. After the First 10 Hours:

  • Change your Oil and Filter. 
  • Do NOT operate at full throttle until engine reaches normal operating temperatures. 
  • Take your engine to full throttle for 30 seconds. 
  • Take note of your full throttle rpm. 
  • We highly recommend operating your engine at 300 rpm under your full throttle rpm or less 
  • Running your motor at 300 rpm under full throttle rpm or less will help avoid damages due to improper fuel/air mixture. 
  • Avoid full throttle acceleration from IDLE speed. 
  • Remember to change your Oil and Filter after the first 10 hours of operation and every 30 hours thereafter.
