Evinrude 150/200 tilt problem

A good friend just bought V6 Evinrude 150 with 200carbs. It lowers and trims down. But will not trim or tilt up. The electric trim motor does run. If we pull up the motor the trim rods will extend but will not push the motor. Its got fluid. What are we missing?
 
you said the motor does run when trimming up? Sounds like an internal oring gone bad, Make sure you have it full of fluid, you need to check it with the motor in the full up position, fill with a squirt can of light oil. If you know its full and wont trim up, there's an o-ring behind the large flat screw on the lower part of the trim system, there's one for up and one for down. One of those screws is on the rear facing side of the trim unit, the other one is on the transom side(you have to remove the engine or trim system). i can't remember which one is which
 
Agreed could be lack of oil or system needs bleeding, try to assist it by physically lifting the the engine whilst someone trims it up to see if its just stuck valve etc .

Remove and clean the manual release valve, check for contamination of the oil, fill her back up to filler hole and test.
 
I do not believe its electrical. We are hooking the trim motor wires straight to the battery right now because there is no black solenoid box. He just got one and I will be installing it tomorrow. He did say the previous owner replaced the trim motor. Could it be a problem with the installation? Spare I will check for the o rings. The trim motor sounds strong and will let the motor down just not push it up. I have tried to assist it with no avail.
 
Are you talking about a relay box that looks this? I since replaced mine with the CDI model as shown in the second picture ....

Yes we tried to use the old relay box. But this Outboard is a 1974 200. The relays would not push enough current to run the motor. The trim motor would barely spin. So now I am trying to figure how to make this dam thing work right. We might just run dual Mercury trim tilt solenoids.
 
it all depends on if the trim motor is a two wire or three wire motor. If its a two wire, the ground is always constant and the up and down are set by the solenoids or relays. If it only has two wires, then the at rest position of the relays need to be to ground, when the relay is activated, it breaks ground before allowing the voltage to feed thru, the opposite relays is supplying ground to the motor while the activated relay supplies the power. You can use the small auto style "cube" relays if you get the correct ones
 
It's got the three wire trim motor. Constant ground. Then a wire for up and a wire for down. I have the relay box shown above and it does not work. The trim motor barely makes a sound.
 
Make sure its at lease a #8 wire 30 plus amps, What is the amperage on the relays, bypass the relay box as a test and see what happens it could be faulty relays or bad pump. Post some pictures it helps ...
 
We have been tilting the motor up and down by putting the trim motor wires straight to the power and ground. No problems there. He bought the relay box of ebay for what we thought the motor was. Then I discovered it was a 74 200. Can we change the relays to higher amp relays? Or should I go with my original plan to get two Merc tilt trim solenoids for $50. The motor is 30 miles away fyi.
 
Yes if the wires are rated for it up the relays to a higher amps will work be sure to completely check from switch to motor for correctly rated wires.
