Engine Installations Guidelines: NOTE: Any available warranty is contingent on following the specified installation guidelines, and completing and returning the installation report form. In the event that an installation report form is not included with the engine it is the responsibility of the customer to call Performance Product Technologies and request a duplicate copy be sent.

Before beginning the marine engine or long block installation please review the following instructions. Verify the root cause of the original boat engine failure because in many cases the cause of the original failure may not have been completely resolved and may have an effect, or cause damage to the new engine. Check the engine assembly for shipping damage. Verify the engine ordered and received is correct for the application. Read all warning tags and additional information supplied with the engine. Contact Performance Product Technologies with any questions.

The intake manifold must be thoroughly cleaned and free of all debris before being installed on the engine. Debris such as old piston/ring materials can become lodged in the intake manifold, plenum, and EGR system. This debris can and will be pulled into the new engine causing pre-mature engine failure.
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 distributor type engine's can be primed with a priming tool and a hand drill to rotate the oil pump drive shaft. Oil must flow to the top of the engine to the rocker arms. Another method before the spark plugs and drive belts are installed can be used. Disable the fuel and ignition systems. 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. Never re-use existing oil coolers and/or oil lines. Check and adjust oil level after priming and purging is complete.
Installer must diagnose, repair and insure 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.
