Mercury Marauder Parts

The Mercury Marauder suffers from clusters of problems centered around engine compression, cooling system plumbing and the fastening integrity of cylinder heads. During engine compression a Marauder may misfire and trip out the warning light at idle or load. On Mercury models, exhaust valve leakage causes a drop in cylinder pressure and results in misfire codes. Repair is done by compression test, leakdown confirmation, and as required, exhaust valve service or head rebuild. A Marauder can have cooling and heater plumbing leaking under the intake with a sweet smell detected when hot. A leaking heater pipe permits the coolant to leak which causes overheating when stuck in traffic or idling. Intake removal and replacement of heater tube services using the Mercury o-ring specifications and torque. The integrity of the cylinder heads influences ignition sealing under high-combustion pressure on a Marauder. The threads of spark plugs may also become stripped which results in emission of plugs with an audible pop and instant misfire. Threaded inserts or cylinder head replacement and proper torque and heat cycle inspection are repair measures. Correct coils and grounds are healthy using electrical checks to resolve Marauder drivability using only mechanical fixes. By doing these steps, they are in line with the Mercury instructions to achieve complete organization of any Marauder that undergoes repair and check.
