Mercury Marine Boat Propellers
Your boat's propeller is like its tyres. It transfers the power from your engine to the water. Mercury Marine propellers have been putting power to the waves for years and are the perfect complement to any Mercury outboard. Choosing the right propeller is a matter of knowing your needs and knowing how a propeller can meet those needs.
The two most common materials for marine propellers are stainless steel and aluminium. Aluminium is light and strong, and makes an excellent choice for most boaters. Stainless steel is both stronger and more corrosion-resistant, but also more expensive. This means steel propellers flex less so they provide more speed for the same HP engine. Steel propellers also support venting, which can also improve overall performance. At the same time, the lower cost of aluminium propellers means that there are far more options available than there are with steel propellers.
The more blades your propeller has, the quicker your boat will accelerate. It's also better when your boat is up on plane because no matter what happens you will never have only one blade in the water with a four or five-bladed propeller. At the same time, three-bladed boat propellers offer the best overall balance of top speed and overall performance.
One advantage of Mercury is the Flo-Torq hub system. One of the traditional advantages of the softer aluminium propellers is that they absorb impact, so that hitting a bank doesn't destroy your lower unit or expensive stainless steel propeller. Mercury's Flo-Torq hub system responds similarly, giving way on impact so as to save your expensive engine and propeller from damage.
Choosing a Propeller
Always choose a propeller based on your needs. A four or five-bladed propeller is good for anyone who spends a lot of time up on plane as they give more acceleration and lift so you can get on plane faster and save your fuel for fishing.
