How do you test a trim motor on a boat?

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.

How do you bleed a hydraulic tilt trim pump?

Bleeding: OB tilt/trim units are “self-bleeding” and you should always perform these “purge cycles” even if you don’t need to add any more fluid. To purge/check, remove the tilt lock (if engaged) and cycle the OB down by “jogging” it down, in 3 second bursts. Then rest the motor about 15 seconds.

Why does my boat not plane out?

A boat won’t plane out either due to a bad propeller, improper motor placement on the transom, wrong trim position, uneven weight distribution in the boat, low engine performance. However, there could be many other reasons, but primarily those elements will cause a boat not to plane.

How do you service an outboard trim?

How do I check my Mercruiser power trim fluid?

Check the fluid level. Open the cap of the translucent plastic reservoir next to the pump if the system is equipped with one. Check the fluid level using the fill mark on the side of the reservoir. Open a container of power trim fluid.

What kind of fluid goes in a trim pump?

SAE 10W30 Automotive Oil

A substitute for outboard tilt-trim oil is automotive oil with SAE 10W30 specification. For example, it is recommended that you use SAE 10W30 oil in older Mercruiser brand trim pumps.

How do you add fluid to power tilt and trim?

How do you bleed a Mercruiser power trim?

Disconnect the leftmost (Up) line from the trim cylinder with an adjustable wrench. Place the end of the hose in a plastic container. Press the “Up” side of the trim switch until a solid stream of fluid comes from the end of the hose. Thread the end of the line into the trim cylinder.

How do you manually trim an inboard motor?

Reach to the back of the engine housing to the back transom — the very back edge of the boat. Look for two metal pins connecting the shaft to the trim-motor. Use an adjustable wrench to unscrew the pins from the trim motor, preparing the shaft-propeller to be raised manually. Leave the cowling open.

What is the difference between power tilt and power trim?

The difference between tilt and trim on a boat is referencing the location of the outboard or the drive of the inboard. Trimming is used when underway and goes about 20 degrees of the way up and tilting is coming all the way up for storage.

Why does the front of my boat go up?

Porpoising, or the bow bobbing up and dow, is caused by over-trimming at cruising speed; there’s no longer enough hull in the water to support the weight of the boat. Either trim down a little until the porpoising stops, or increase boat speed slightly to create more lifting force under the hull.

How do you manually lift a boat motor?

What happens if outboard motor is too low?

If the outboard is too low, it creates excessive drag, which cuts into speed and fuel efficiency. If it’s too high, the propeller tends to ventilate, losing its bite on the water and blowing out while turning and in steep seas.
