Installation

Before beginning the marine engine or long block installation please review the following instructions.

After installing the engine, rotate the crankshaft a minimum of 4 complete revolutions before engaging the starter. Nuts, bolts, washers or other small parts that may have been dropped in the intake can severely damage the replacement engine. If the engine cannot be rotated by hand, inspect for foreign objects in the combustion chamber.

The oil pump must be primed and the entire oiling system must be purged of air before the drive belts are installed and the engine is started. The preferred method is to use a pressurized system to push clean oil through the entire system. However the is another method that can be used before the spark plugs and drive belts are installed:

  1. Disable the fuel and ignition systems
  2. Crank engine in short durations until oil pressure is achieved. Then an additional 2 minutes in short durations to insure the oiling system is purged of air.
  3. Check and adjust oil level after priming and purging is complete.

The installer must diagnose, repair and ensure proper operation of engine related systems and sub-systems. Failure to make repairs to these components may result in engine failure.

The installer must verify that the proper gauges (oil pressure & coolant temperature) are functioning properly. The manufacturers will not cover warranty on products that experience oil starvation and overheat since it is required to have the engine protected by these gauges and the associated alarm systems.

Breaking In

The first 20 hours of use is the engines break in period. Correct break in is essential to obtain minimum oil consumption and maximum engine performance.

During the break in period you must follow these rules:

  • Do not operate below 1500 RPM for extended periods of time for the first 10 hours. Shift into gear as soon as possible after starting and advance throttle above 1500 RPM. If conditions permit safe operation
  • Do not operate at one speed consistently for long periods of time.
  • Do not exceed 3/4 throttle during the first 10 hours. During the next 10 hours, occasional operation at full throttle is permitted (5 min Max).
  • Avoid full throttle acceleration from idle speed.
  • Do not operate at full throttle until engine reaches normal operating temperature.
  • Frequently check crankcase oil level. Add oil if needed. It is normal for oil consumption to be high during break in period
  • After 20 hours break in period, drain crankcase oil and replace oil filter, refill with the correct amount of new oil.
