The retrofitting of the outboard motor is not just a fashionable thing, it's a real opportunity to improve comfort and safety on the water. electrotrimmerIt's a device that allows you to remotely control the tilt of the lower unit, and if you're used to climbing out of the cockpit and turning your nuts or levers by hand, the switch to electric is a revelation, and it takes a lot of physical work, allowing you to adjust the angle of the dispersion with the push of a button on the tiller or remote control.
The modern market of water-motor technology offers many solutions, from budget Chinese analogues to time-tested European systems. Electrical drive This is especially true for medium-power engines, where manual lifting is still possible but requires effort, and for heavy PVC boats, where every extra kilogram of weight on the transom is critical. In this article, we will take a detailed look at the design, selection and finesse of the installation so that you can make the right choice.
Introducing electrohydraulics or electromechanics into your outboard motor requires an understanding of the basics of hydraulics and electrical engineering. Incorrect installation can lead to oil leaks or electronics failure, so it is important to carefully study the instructions. We will look not only at the theoretical aspects, but also at the practical nuances that water motors face in real-world operating conditions.
Principle of operation and system design
Underlying any electrotrimmer There's a bunch of motors and hydraulic pumps (or mechanical propellers in simpler models). When you press the Trim Up button, the electric current triggers a motor that spins the gears of the pump. The pump creates pressure in the hydraulic system by pushing fluid into the cylinder, which causes the rod to extend and raise the lower unit. To lower ("Trim Down"), the process often occurs for an outboard motor's own weight, although in high-power systems there is a forced hydraulic descent.
The key element here is hydraulic unitIt has to be sealed and resistant to corrosion. Budget models often use plastic gears in the drive gearbox, which is their weak spot at high loads. HydraSport or Lenco (although the latter are more common for stationary systems), use metal gears and high-quality seals designed to work in an aggressive salty environment.
It is important to understand the difference between systems Power Trim and Power TiltThe trimmer is responsible for working adjustment of the angle of inclination during the movement (usually in the range of 10-15 degrees), allowing the boat to be plane. The tilt is designed to fully lift the engine out of the water when approaching shore or transport. Many modern kits combine these functions, but when choosing used equipment, it is worthwhile to specify what range the mechanism provides.
The efficiency of the system depends on the quality hydraulic fluidUsing the wrong oil can foam, corrosion of internal channels and system failure at the wrong time. Some manufacturers recommend specific types of ATFs, while others insist on special hydraulic oils for marine applications.
Can an electric trimmer be used on motors with a capacity of more than 15 hp?
