Mercury Outboard Engines & Components
Tame the waves with a Mercury Marine outboard motor at your back. Built in a range of sizes, builds, and displacements, durable Mercury engines serve you in a range of applications. Whether you need a powerful craft for commercial and athletic needs or something peppy for family outings, you will find a Mercury outboard that fits your needs.
What kinds of gearboxes fit your Mercury outboard?€
Mercury outboard motors come in a variety of shapes, horsepower (HP) ratings, and sizes. If you get a gearbox capable of harnessing your horses, you will improve your performance. You can use a variety of gearbox designs with Mercury engines. The following is a list of some common choices.
- Torque master: 19-splined, stainless steel gearbox that offers extra durability, less slippage, and better performance than plastic or aluminum. This makes them a common choice for larger and heavier powerboats.
- Sports master: Much like its cousin the torque master, the sports master features a stainless steel spline. This gearbox includes race-ready design factors like liquid-dynamic curves for less friction and more speed.
- Heavy duty: This gearbox lives up to its nickname. Constructed of stainless steel, its design includes specially processed pinion gears and a gear ratio in the 1.75:1 range. The heavy duty gear ratio gives you a combination of performance and efficiency, ideal for high-HP crafts.
Do you need special propellers for Mercury Marine motors?€
Not necessarily, but Mercury provides you with specialized quick-replace propeller shafts. Unlike friction driven hubs, low-torque hubs use gear-splines for leverage and grip. The unique design of these propeller hubs lets you replace some propellers out in the field.
What are sacrificial anodes?€
Sacrificial anodes are special metals that are especially prone to corrosion. When mounted on less corrosion-prone materials, sacrificial anodes break down first. In the process, they protect the underlying materials from rust.
Do electronic ignition motors have back-ups?
Most do. Electric ignition engines use batteries for startup power, and if these batteries lose power it can be hard to find a jump on the high seas. To solve this potential problem, motor makers usually include manual start-up controls on smaller electric motors. When replacing your backup motor, look for models that offer hand-powered battery recharging.
Should your new engine be stronger than your last one?
It can be. If you opt for a larger replacement motor, you should check the power/HP ratings for your current craft. These numbers give you precise information about your boats performance limits, and they tell you how to coax more out of your current propeller.
