“Due to the damage potential with these engines from things such as water ingestion, corrosion, parts coming loose or breaking, and countless other issues, staying on top of your marine engine maintenance is crucial. While the basic machine work required to build a marine engine is essentially the same as an automotive engine, that’s where the similarities end.
Marine engines have an entirely different operating environment than automotive engines. They typically spend most of their time at cruise or full throttle. Cruising speed for a boat is a lot different than that of an automobile cruising down the highway. Cruising rpm for many of these marine engines is 3,500 to 4,000 rpm depending on the drive ratio and prop size. By comparison, a typical automotive engine will only be turning 1,600 to 2,000 rpm at highway speeds.
Another important difference between boats and cars is that boats don’t coast. The motor is always pushing the boat forward. There’s no backing up and a boat can’t use the engine for braking. If an inexperienced driver is running full throttle and suddenly lets off on the throttle, a small boat can nose dive and may even flip over!”

Many of the problems that occur with outboard engines is due to the water itself. This is especially true with saltwater corrosion. Boat owners should always flush their engines after usage with a garden hose attached to the flushing part. Flushing after every saltwater excursion will absolutely extend the life and usability of your engine.
