How do you test a mercury trim motor?
To test the motor itself, bypassing the relays and relay wiring, find the two heavy gauge wires that lead to the trim/tilt pump motor. One should be green and the other blue. You will probably be able to find a quick disconnect plug near where the wires exit the outboard engine cover that you can disconnect.
What is power trim on an outboard motor?
Most outboard motors and stern drives have power trim that lets a user change the angle of the thrust by tilting the drive or motor in or out to change the running angle. A boat handles best when it’s running parallel with its at-rest waterline. Outboard motors can be trimmed to adjust a boat’s ride and attitude.
How do I know if my trim solenoid is bad?
Use a jumper from the battery and touch the small lug of the solenoid with the colored wire. Solenoid should operate. Solenoid clicks, but motor dosent run, solenoid is bad. Solenoid does not click, then sheck the ground wires on the solenoid.
How do you check a power trim motor?
Touch the other end to the blue wire on the motor. As soon as you touch the battery cable to the blue wire, the motor should start to spin clockwise. If the motor fails to spin, then it is defective and needs to be replaced.
What is the difference between power tilt and power trim?
Power tilt is for low speed o Power tilt is for low speed operation and saves the back while on the trailer. Power trim means you can adjust motor at full throttle. You can buy motors with just power tilt.
How does power trim work on outboard?
Most boats handle best when running parallel with their at-rest waterline. Accordingly, outboards and sterndrives feature a power trim adjustment that allows you to change the engine’s angle of thrust by tilting it “out” or “in” in relation to the transom in order to maintain the proper running angle.
Should you leave your outboard up or down?
You want to leave the engine in the totally trimmed down position. This will allow all of the water to leak out of the engine, midsection, and lower unit. Making sure that there is not any water in the Lower Unit that could rust gears or freeze and destroy the gear case by flushing the engine with fresh water.

Transmission fluid type F is a substitute that can be used for outboard motor tilt-and-trim oil. Automatic transmission fluid has a high amount of detergent in it, so be sure to check your owner’s manual.

How does a trim motor work on a boat?
A trim motor can change the angle of your outboard engine so that you can put it in an optimal position. Trim motors run with electro-hydraulic power. An electric pump moves fluid when needed, and its this movement that changes the thrust angle of the outboard.
Can a tilt and trim unit be added to a outboard?
Some tilt and trim units are made for smaller engines, like those with 35 horsepower or less. Other units have been designed for more powerful, and therefore heavier, outboards with greater horsepower. Many Mercury boat outboards, like those listed below, can be fitted with trim and tilts.
