Though they are becoming more and more rare, parts for OMC S/D engines, such as OMC Sea Drive power packs, are still available through commercial outlets. There are still dealerships that specialize in OMC genuine parts, providing factory-direct quality for OMC outboard or sterndrive owners. OMC Sea Drive power packs are available, as are OMC carburetor kits, propellers, and shop manuals, among others.
The power pack on an outboard engine is a key component of the electrical system of an engine. It is a computer-controlled box that distributes power to each of the spark plugs in turn, firing them to ignite the fuel in a cylinder and initiate the power stroke. OMC Sea Drive power packs are located in the power head of an outboard, adjacent to the cylinders.
Testing for Damaged OMC Sea Drive Power Packs
Occasionally, an ignition system part may become damaged by corrosion, age, or some other factor. If your engine doesn’t seem to be receiving any spark from the spark plugs, the power pack could be at fault. The wiring and connections may also be dirty or damaged, or it is possible that the stator, ignition switch, or amplifier coil may be damaged somehow.
By testing each item according to the specifications set forth in your OMC S/D parts manual, you may be able to determine where the fault lies. The service manual should provide you with information about the peak voltage of each item, which you can compare to readings from a multi-meter. Troubleshooting this way can help save you time, work, and expensive shop fees.
