See full version: If the Trim Fails, can you lift the outdrive
Re: If the Trim Fails, can you lift the outdrive?
Or. If the Trim Pump were to Fail.
You could Disconnect the 2 Hyd. Lines from the Pump,+ Then Manually Lift the Drive.
There'll be Oil squirting from the Lines, so direct them into a Jug.
So, 1) try the jumper test first, then.
2)if that doesn't work, then disconnect the hydralulic lines as Bondo states. [links]

Re: How to raise motor if power tilt fails?
On the bottom of the hydraulic pump is a relief valve. Open theis a quarter turn, and you can left the motor up. On some engines you get to this valve through a hole in the mounting braket. Don't loosen any lines. here
This will, however, cause the tilt fluid to spew out, so you want to have a catch pan handy.
The only way I know of is to crack open the lines to the pistons, and release the hydraulic pressure, then you can manually tilt it.
I do understand your frustration because my merc did the same thing to me.
I have gone through every electrical connection on a boat and in the engine too. You can not assume just because it feels tight that it is making proper contact. I remove every connection one at a time and sand the contact with plumbers cloth or 220 sand paper. Then I re-install, make sure it is tight and then I coat with a tiny touch of grease if needed.
Re: 40 hp Merc Power Trim Issues more
Your biggest enemy is corrosion. I have been there, done that and have the t-shirt. Here is what I have done.
Note that the Trim up wiring goes thru the Trim Limit Switch located on the port side of your outdrive and then to the Solenoid. The Trim up and Trailer buttons both use the same solenoid so if the Trailer button works the problem may be in the Trim Switch or the Trim Up button. If its the trim switch on the outdrive that has failed, you will be into pulling the outdrive to replace the switch & wiring and while you are there, you may as well replace the Trim Sensor switch if it isn't working along with any other items that are showing some wear. If it gets to that point, see WetWilly's "Sticky" on replacing the Trim Sensor & Trim Limit Switches.
More testing needed? Refer to the attached drawing:
All circuits inoperative : Connect a voltmeter between point 5 & ground. Depress the In/Down button. Move the red voltmeter lead to point 3 & depress the Out/Up button. If no voltage is shown at one or both test points, check the connections at points 2,3,4 & 5. If connections are good, the solenoid(s) will need replacing.
Disconnect the blue/white lead at the solenoid terminal point 8. Depress the In/Down button. If the pump motor operates there is a short in the wire harness. more
When experiencing problems with your power Trim and Tilt System, there are a few easy ways to diagnose just what the problem is. Power Trim motors generally come in two styles. All use a 12 volt D/C reversing Motor. Some Motors have a two wire connection and some Motors have a three wire connection. All power Trim and Tilt Motors come with one blue wire and one green wire. The three wire power Trim and Tilt Motors have an additional Black wire as well. The Black wire works as a Ground on power Trim and Tilt Motors that don’t ground thru the case. When the blue wire is energized it raises the Motor or drive unit up. When the green wire is energized it lowers the drive unit down.
Another common symptom of a bad air pump is a reduction in power output from the engine. Again, a failed smog pump can upset the tune of the vehicle, which will negatively impact overall engine performance. A failed air pump may cause the engine to hesitate or stumble on acceleration, and in more serious cases, cause a noticeable reduction in total power output. here
An air pump, also commonly referred to as a smog pump, is an emissions component that is part of the secondary air injection system. It is responsible for pumping clean air into the vehicle’s exhaust stream to promote a cleaner and more complete burn before the fumes exit the tailpipe. By injecting clean air into the exhaust, the amount of hydrocarbon pollutants produced by the vehicle is reduced, as the entire system is finely tuned to run with the air provided by the air pump.
Another symptom that may be indicative of a bad air pump is an illuminated Check Engine Light. This will usually only occur after the computer has detected the air pump has completely failed, or an electrical problem with the air pump circuit has occurred. A Check Engine Light can also be caused by other problems, so it is important to have the computer scanned for trouble codes before making any repairs. here
One of the first symptoms of a bad or failing smog pump is a rough running engine. When a smog pump fails the finely tuned air-fuel ratios can be upset, and it will negatively affect the performance of the engine. The engine may have trouble idling, and may drop in engine speed, or stall when the pedal is pressed. more
The air pump is an important component of the emissions system, and necessary to keep your vehicle running in proper order so that it can meet the proper emission requirements. If you suspect that your air pump may be having a problem, or your Check Engine Light has come on, have the vehicle diagnosed by a professional technician, such as one from YourMechanic. If necessary, they will be able to replace the air pump and restore proper performance to your vehicle. [links]
