Review QUICKSILVER New Mercury Oem Gear Part No. fits MARINE

The Quicksilver 43-803740 Mercury Marine Gear is a high-performance, reliable, and efficient propulsion system designed specifically for Mercury Marine outboard engines. This gear is an essential component of your boat's powertrain, responsible for transmitting power from the engine to the propeller, enabling your boat to move smoothly and efficiently through the water.

The Quicksilver 43-803740 Mercury Marine Gear is a two-stage, helical gear design, which provides several advantages. The two-stage design allows for a smaller gear case and reduced weight, making it an ideal choice for smaller outboard engines. The helical gears have a quieter operation than straight cut gears, resulting in a more pleasant boating experience.

This gear is constructed using high-quality, corrosion-resistant materials, ensuring long-lasting durability and reliability. The gears are made from marine-grade bronze, while the gear case is made from fiberglass reinforced polymer (FRP). The use of these materials provides excellent protection against the harsh marine environment, preventing corrosion and damage from saltwater, sun, and other elements.

The Quicksilver 43-803740 Mercury Marine Gear also features a robust, heavy-duty design, capable of handling the demands of high-performance boating. The gear has a large, oil-cooled, one-piece aluminum propeller shaft, which helps to dissipate heat and ensure optimal performance. The gear case also includes a built-in, oil-filled ventilator, which helps to maintain proper oil temperature and pressure, ensuring the gear operates at peak efficiency.

The gear comes with a high-capacity oil pump and oil cooler, which help to maintain the proper oil temperature and pressure, even during heavy use. The oil pump is designed to provide ample oil flow to the gears, ensuring quiet and efficient operation. The oil cooler, on the other hand, helps to dissipate heat, preventing the oil from overheating and damaging the gear.

The Quicksilver 43-803740 Mercury Marine Gear is also designed for ease of installation and maintenance. The gear comes with a bolt-on design, making it easy to install and remove. The gear case includes a removable bottom plate, which allows for easy access to the gear for maintenance and repairs. The gear also features a large, easy-to-reach oil fill plug, making it convenient to add oil as needed.

In conclusion, the Quicksilver 43-803740 Mercury Marine Gear is a high-quality, reliable, and efficient propulsion system designed specifically for Mercury Marine outboard engines. With its robust, heavy-duty design, quiet helical gears, and easy installation and maintenance features, this gear is an excellent choice for boat owners looking for optimal performance and durability on the water.
