Took my boat out for a shake down today , it seems the power tilt that was working fine , stopped going up . Will go down but won't come up . The hydraulic thingie doesn't even register when I push up switch , however I can hear a click somewhere else (sealed box with several wires in and out ) .Any ideas whats gone wrong . its an early 90s merc 60 hp
Check you have power at the tilt and trim motor, this will tell which way to go, motors are pretty simple, could be brushes or worn bushes, motor has tie rods down into the pump housing. Don't damage the magnets in the motor
definitely as Maca says, funny but the motor works harder lowering than lifting. check oil for air and also check screw on the side of the trim lift for tightness.

Ok some help please , so Ive got power to my pump motor , so it must be the motor , it was very dirty inside . I've cleaned it and put it back together but still not work . How clean does it need to be ? . Any other tips or tricks to get this working ?
Are the brushes making contact with the spindle?
It looks like they where they supposed to be , got spring loaded wire arms that I set once in place . @Maca49 what do you think ?Quote:

Since you have the motor out, If you put (I assume 12V) on the leads with it all assembled does it spin??
If it does I might be looking else where in the supply line
And then swap leads and make sure it spins the other way.Quote:

Let me know if you want a hand Munsey.
Should have bought a Johnson:P
There is a contact in there ( maybe an overload ) will find some fine paper to clean contact face . And clean again . Will check for damage Magnets . Will fine oil help on the shaft , bearing ?
Yep
When the motors together you can turn it by hand? It will be chunky with the magnets
If it was going one way but not the other I would have thought problem in control circuits somewhere? but I am not a sparky nor have I ever pulled a trim unit to bits.
Does the motor(and therefore pump) actually run two directions normally or is there a solinoid that reverses hyd flow for the other direction and motor and pump only run one direction?
I dont know just throwing it out there....
Maybe a thermal overload?
That's sounds and looks about right .Quote:

About bloody time!:thumbsup:
Well dont leave us hanging what was the verdict ?
Dirty contact , fine sand paper sorted it .
Holy shit all that grief for a quick hand job:D
Good stuff, easy fix, not normally that way with boats, but life is better by the sea, and great on the sea, dark giving way to dawn, slight mist, dead calm, slight swell, the sweat sound of a reel singing, as a good size fish realises its mistake. Put down the hot coffee and pick up the rod, yeaha!!!.
