If the tilt and trim motor works fine but the engine won’t raise or lower, slips down when in the raised position or won’t stay trimmed, chances are that the problem is with the hydraulic pump or valve body assembly. If the level is adequate, the problem is most likely with the hydraulic pump.
How do you test an outboard motor trim?
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.
Is there a fuse for tilt and trim?
Re: fuse location for trim and tilt It is a blade fuse. It only fuse protects the control side of the T system. The power side, the power source to the motor, is not fused.
How do you get air out of tilt and trim?
Trim up and deploy the trailer bracket. Crack open the cap for the reservoir to release any trapped air. If the fluid trickles out then your level is fine. Repeat if necessary.
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. Stand at the back of the boat and have an assistant stand to the other side. Push the lock pins you unscrewed from the motor through the trim settings in the cowling area. Close the cowling.
Should I leave my outboard motor up or down?
Should I leave my engine up or down? Simply put, if you are leaving the boat in the water, leave it in the up position to avoid growth. If you are leaving it out of the water, trim it down to drain the water and protect the Power Tilt and Trim seals from the sun.
What’s the difference between tilt and 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.
How many amps does a trim motor draw?
The current draw from a power trim/tilt motor is typically approx 30 Amperes.
How to troubleshoot a marine engine trim pump?
If necessary, trace the wires to the front of the engine near the slave solenoid. One wire is grounded near there and the other is connected to a terminal. If you don’t get a voltage reading at the terminal junction, apply 12 VDC to see if the trim gauge moves. If it does, check for voltage back at the trim pump connections.
What is the problem with power tilt and trim?
When the PTT unit is as it should be, the electric motor runs, the manual release valve is closed, the unit is full of lubricant, and nothing works, the usual problem is an air lock under the oil pump Proceed with the following. Engine in full tilt position. Remove reservoir fill plug screw.
When did power tilt trim motor come out?
It appears to be unavailable at Bombardier but it might be available at Sierra under Sierra’s part number of 18-6761. This POWER TILT TRIM electric motor existed between 1982 thru at least 1992. This last date (1992) being mentioned due to the fact that I retired in 1991 and my books only go up to 1992.
What to do if your trim pump does not work?
If it does, check for voltage back at the trim pump connections. If no voltage there, apply 12 VDC there to check gauge movement. Next check the three wire connector (RED, BLUE & GREEN) at the pump assembly. This plug can vibrate loose and cause your problem. Pull it off and see if the pins are clean and not corroded; reconnect it.
