Mercruiser Trim Pump Wiring Diagram

The Mercruiser Trim Pump is an essential component of the Mercruiser Sterndrive system, which is responsible for the raising and lowering of the boat’s propellers. The power to the trim pump is transmitted through the wiring system, which comprises a number of key components. In this article, we will provide a comprehensive guide to the Mercruiser Trim Pump Wiring Diagram, along with a detailed explanation of each of its individual components.

Overview of the Mercruiser Trim Pump Wiring Diagram

The Mercruiser Trim Pump Wiring Diagram consists of three main components: the switch, the motor, and the solenoid. The switch is mounted on the boat’s control panel and is used to control the up and down movement of the propellers. The motor is located inside the pump and is responsible for providing the power to drive the pump. The solenoid is an electromagnetic switch that regulates the flow of electricity to the motor.

The Switch

The switch is a simple component that is mounted on the boat’s control panel. It typically consists of two buttons: one for raising the propellers and one for lowering them. When the switch is pressed, it sends a signal to the solenoid, which, in turn, activates the motor.

The switch is connected to the solenoid using a wiring harness, which is typically made up of four wires: red, green, black, and purple. The red wire is connected to the positive terminal of the battery, while the black wire is connected to the negative terminal. The green wire is connected to the motor, while the purple wire is connected to the solenoid.

The switch is designed to be waterproof and is typically made of high-quality materials that are designed to withstand the harsh marine environment.

The Motor

The motor is the heart of the Mercruiser Trim Pump and is responsible for providing the power to drive the pump. The motor typically consists of a series of coils that are rotated by a magnetic field. As the coils rotate, they generate a magnetic force that drives the pump.

The motor is connected to the solenoid using a wiring harness, which is typically made up of two wires: green and blue. The green wire is connected to the switch, while the blue wire is connected to the solenoid.

The motor is designed to be waterproof and is typically made of high-quality materials that are designed to withstand the harsh marine environment.

The Solenoid

The solenoid is an electromagnetic switch that regulates the flow of electricity to the motor. When the switch is pressed, it sends a signal to the solenoid, which, in turn, activates the motor.

The solenoid is connected to the switch and the motor using a wiring harness, which is typically made up of three wires: purple, blue, and yellow. The purple wire is connected to the switch, while the blue wire is connected to the motor. The yellow wire is connected to the positive terminal of the battery.

The solenoid is designed to be waterproof and is typically made of high-quality materials that are designed to withstand the harsh marine environment.
