Impeller vs Propeller: What’s the Difference & Why It Matters for Your Outboard Engine
Gas-powered boats depend on impellers and propellers to perform different functions. Propellers push boats through water. The impeller acts as the heart of engine cooling systems and pumps water to regulate temperature and prevent overheating. The difference between impellers and propellers goes beyond their basic functions. Impellers move water faster than propellers and provide better […]
What Is A Fuel Water Separator – And Do You Really Need One On Your Outboard?
Water weighs 2.5 pounds more per gallon than gasoline, which makes a fuel water separator vital to protect outboard engines. This fact emphasises how crucial this often-overlooked equipment really is. Your engine can develop serious problems from even tiny amounts of water. These include fuel system corrosion, poor combustion, stalling, and damaged injectors and carburettors. […]
What Is an Outboard Impeller? (And Why Replacing It Could Save Your Engine)
The difference between a smoothly running boat and an engine failure that can get pricey might come down to a small fan-shaped component.

Still Running a Mariner Outboard? Here’s What You Need to Know (Parts, Problems & Performance)
Running out of gas remains the number one reason boaters get stranded with mariner outboards. Most outboard motor problems originate from three vital systems: air, fuel, or electrical (spark). These systems can cause stalling, misfiring, or startup failures when disrupted. Power loss can occur due to conditions like bad fuel, overheating, and loose connections. Mariner […]
How Do Sacrificial Anodes Work (and Which One Does Your Outboard Need?)
Sacrificial anodes play a vital role in boat maintenance as highly active metal components that shield less active metals from corrosion. Bronze or aluminium propellers on stainless steel shafts face the most damage from galvanic corrosion. These protective devices prove crucial to boat owners. Your valuable marine equipment needs protection, and knowing how sacrificial anodes […]
How to Use the Flush Port on a Yamaha Outboard
Your Yamaha outboard engine lasts longer if you use the flush port correctly. If you boat in saltwater, flush your outboard after every single trip. A clean-water flush pushes out contaminants like sand, silt and mud from your cooling passages. It also removes salt deposits that can harm cooling and cause corrosion in the engine […]
2-Stroke vs 4-Stroke Outboards: What’s the Difference & Which One’s Right for You?
Whether you’re a seasoned boating enthusiast or just getting started with your first vessel, one of the most important decisions you’ll make is choosing the right outboard motor. How your boat performs on the water, from its speed and fuel efficiency to handling, and even noise levels, depends heavily on whether you go with a […]
