How saltwater affects boat engines

Saltwater has a very tangible impact on boat engine. It accelerates the corrosion process. When this happens, it leads to rust, which can cause damage to engine parts such as the cooling system, gearbox, exhaust system, and even to the engine block itself.

The role of temperature and humidity

Temperature and humidity can exacerbate saltwater corrosion. Hot, humid climates, especially in conjunction with regular saltwater exposure, can accelerate the rusting process. The salt crystals left behind by evaporated water can bind to the engine, exacerbating wear and tear.

Types of Boat Engines

Just as there are many types of boats, there are also different types of boat engines, each with their own unique characteristics and maintenance needs.

Inboard engines

Inboard engines are those located inside the boat’s hull. They’re commonly found in larger boats and provide a lot of power. However, their location inside the boat can make them more susceptible to saltwater damage, and they may require more in-depth maintenance.

Outboard engines

Outboard engines, on the other hand, are mounted on the outside of the boat. They’re easier to maintain and repair than inboard engines, making them popular among small boat owners. They can also be lifted out of the water when not in use, reducing their exposure to saltwater.

Sterndrive engines

A sterndrive engine strikes a balance between inboard and outboard engines. It’s installed inboard for better weight distribution, but driveshaft and propeller are outside, like an outboard. This unique design means that sterndrive engines share maintenance traits with both inboard and outboard engines.

Routinely Inspecting the Engine

Frequent inspection of your boat engine is critical, especially when often boating in saltwater.

The importance of regular checks

Regular checks can prevent small issues from becoming major problems. Inspecting your boat engine routinely allows you to catch signs of wear and tear or corrosion early on, allowing you to address issues before they cause more serious damage.

Dealing with corrosion or damage

Corrosion or damage should be addressed immediately to prevent further issues. Depending on the extent of the damage, you may require professional assistance. If caught early, you might be able to treat minor corrosion with an anti-corrosion product.

Flushing the Engine After Use

Proper maintenance after use, especially in saltwater, is crucial to expanding the lifespan of your boat engine.

Why flushing is necessary for saltwater boating

Saltwater can lead to corrosion and buildup in your engine. Flushing your engine after every use can rinse away the salt and prevent these problems from occurring.

How to flush your boat engine

To flush your boat engine, connect a hose to the engine’s flushing port and let fresh water run through for several minutes. Make sure the engine is turned off when you’re flushing it. For thorough cleaning, you might need engine flushing products designed for saltwater boating.

When to flush your engine

Ideally, you should flush your engine after every use in saltwater. But if that’s not feasible, at least aim for a regular weekly or bi-weekly flushing schedule.
