Times not always on your side
The importance of regular maintenance can never be stressed enough. The owners manual usually spells out just what exactly one should do to prevent premature failure.
As we move into a new century, many of us have taken these procedures for granted, often ignoring the dangers of those actions. We depend on lights and buzzers to tell us that it's time to pay attention to our cars, boats, and other machinery. But unfortunately, the warning device doesn't always work as designed by the manufacturer. There may be circumstances under which a damaging situation can arise, and the warning lights and buzzers don't activate. Although we'd all love to blame the manufacturer, and some blame does lie there, the truth is that we need to ask ourselves, did we do all we could do to prevent damage to our engine or boat.
The answer to that question can best be answered by one good example. The manufacturer for brand XYZ, produces a product that recommends that the water pump impeller be replaced every season. Brand XYZ recently improved their design for a certain water pump model, claiming the benefits of it's new design. The older model pump, (in production for over twenty years) had an intolerance to running dry but contrary to the recommended service interval, typically, lasted several seasons. When it started to fail, for what ever reason, the engine would over heat, the lights and buzzers would go off and the owner would know it was time for a new impeller.
The new model water pump had all the signs of a successful replacement to it's dependable predecessor, until that frightful day, when the new product was handed to "The Retail Public".
