Author Topic:   Evinrude trim and tilt problem

hookup66 posted 07-24-2010 11:27 AM ET (US)
My 1996 Evinrude 70 trim and tilt stopped working. It is in the down position. I've got power to the 2 plug in relays(I think that's what they are). Because the motor is down, i cant access the actual motor. Also, I can't get the over ride screw to budge. Any suggestions? Thank you.

You could keep checking for power from the relay down to the motor. Check for voltage at the relay where the trim motor wiring comes in when you push the switch. In other words don't just verify that you have power to the relay, verify that you have power OUT.
Then, there may be a connecting plug between the relay and the motor leads, so again check for power at any connection.
Also try tapping, shaking, and jiggling the engine while trying the trim switch. If you have an intermittent connection in the wiring, you may get lucky and get it to catch so you can raise the engine.

Try to use a large screwdiver (Craftsman, Snap on) has a square shank you can put a wrench on to help turn the bleed screw/over ride screw....good luck

The release screw on the side of the engine mounting I think maybe clockwise to unscrew as this caught me out one time
The bleed screw below the rams on the cylinder I also found very tight
My fault in the end was the relays

Trace the heavy gauge blue and green wires from the relay sockets until you find the connector which you can unfasten and check for corrosion. At those 2 wires going to the trim motor, use jumper wires connected to a battery to see if the motor is operational.

Might sound silly but check the hydraulic fluid to confirm you still have some. No fluid no pressure no tilt at all. Its hard to sometimes tell if it truly is low so you can always buy a small container of fluid and top it up. I have found if it is on the low side the tilt will not work properly. Hopefully at this stage its just low and thats it. The next thing to consider if it really is out or low, why is it getting low. My guess is that it could be a seal specifically the lower seal on the cylinder the one that usually sits just below the water line. I just replaced two tilt motors for my boat because of the two seals that were leaking fluid. It wasn't that obvious with one but the other motor was so obvious it was streaming out into the water unfortunately. It was easy to check and confirm that both were gone. The seal kits cost nothing but the labour is tricky. Be careful there may be water that has entered the cylinder due to the design of the bottom seal so usually its best to replace the whole tilt system given the cost of labour involved as well corrosion that can settle in over the years. I hope its just low or something else that is not costly. It is a pain but your engine is probably still manageable to lift manually although still not fun. I wasn't so lucky with twin 225's. YIKES!

Hope to work on it tuesday. Initially, the challenge is going to be getting that manual overide screw to budge. It looks a bit buggered up already. I'm not sure that I can test any of it until I get the motor up? Thanks for the suggestions, will post my progress.

Will do, thanks again, Jeff

Tried to activate the motor by connecting wires from a battery to the green and blue. Nothing. No clicks, nothing. Any suggestions. I can't get the manual overide screw to budge.

Hang the engine and replace the motor.
hookup66 posted 08-02-2010 01:07 PM ET (US)
That's a great suggestion. Time to start saving some Cash.
Tohsgib posted 08-02-2010 01:24 PM ET (US)
They are not that expensive that you need to start saving, less than $200. You would not need to disconnect everything, just hang the engine off the trailer and reove the 4 screws and replace. No matter what you are going to have to loosen that screw, you will need to fill it with ATF to work. Screw is counter rotation I believe.

Hookup:
Just in case it is more than the motor and extends to the hydraulics take a look at the photograph of the tilt trim assembly from one of my 1997 Johnson 200 hp Ocean Runners. If the motor is gone today, check that the hydraulics don't go tomorrow --- look at the seals.

If you do it yourself, the assembly can be purchased online at a discount from the steep Evinrude list of $1262.47 (same price for the 70 and 200). With a dealer, the installed cost is high enough to make one think about a new engine (which are much, much better than the 1990s carbed 2 strokes). I now have two hydraulic assemblies for a total installed cost of about 8% of two new engines but that is another story...if you have the means, take the opportunity to replace the whole engine and you will enjoy your boat so much better (plus you will be green).

Thanks again for all the great info.

Finally solved my trim and tilt problem.
I removed the 96 Evinrude from the boat and sold it for $700 as is.
I found a great price on a crated Yamaha F90 and plan to mount it up soon. thanks for all the info.
