IMPORTANT: All Mercury remanufactured 4-cycle engines are temporarily fit with electrical systems, fresh water, and premium fuel to perform a series of "Hot-Test" validations for quality control purposes. Thereafter, the engine oil drains back into the pan and looses its lubrication value from the valve-train and cylinder walls. We require the installer to perform an "Oil Priming" procedure prior to the engines initial start-up to reduce the potential for premature bearing failures.
Note: There are two different methods to prime an engine prior to ignition. Either can be used.
Method A - Utilizing a standard GM engine-oil Priming Tool (purchased locally).
Method B - Performed with a Remote-Starter-Switch (tool # 91-52024A 1).
METHOD A - (preferred)
1. Fill engine crankcase to proper level with recommended marine engine oil.
2. Remove the complete distributor assembly.
3. Install the oil "Priming-Tool" into distributor bore and onto the oil pump shaft
4. Rotate the oil pump with an electric drill for approximately 2-minutes, or until oil pressure registers on an oil pressure gauge.
5. Remove the priming tool and reinstall the distributor according to instructions outlined in a MerCruiser Service Manual.
METHOD B - (optional)
1. Fill engine crankcase to proper level with recommended marine engine oil.
2. Remove all spark plugs.
3. Disconnect the high-energy wire from the distributor and connect it to a good ground.
4. IMPORTANT: Leave ignition key in the "OFF" Dosition.
5. Connect one end of the "Remote-Starter-Switch" to the 12-Volt red oositive battery cable terminal and the other end to the smaller (yellow-red) terminal on the starter motor. Note: If you opt to use the ignition switch instead of the remote-starter, disconnect the PUR wire from the coil before turning the key. Cover the PUR wire with tape to avoid a possible ground condition.
6. Crank the engine over for approximately 15-18 seconds. Let the starter motor cool down for i-minute before cycling again. Repeat this process § more times.
7. Remove the Remote-Starter-Switch, or reconnect the PUR wire to the ignition coil.
8. Install the spark plugs and plug wires.
9. Start the engine with a good supply of cool water.
