If you get no help here try the Mobo forum.

The raggies who use this forum don't know anything about outboards bigger than 8hp.

If still no help try the Mercury/ Mariner board on the iBoats forum http://forums.iboats.com/forum.php

or MarineEngine.com http://www.marineengine.com/boat-forum/forum.php

BUT give the full model details including HP, year and/or serial number

At the back left of the engine tray you should have 1 or probably 2 relays.Either loose connection or knackered relay.To check motor try 12v direct to the blue and green wires.Reverse the polarity for up and down.

I agree with single, had the same problem on a Mercury 50, there should be two relays probably on the starboard side, fairly low down. They are in rectangular plastic boxes about 50mm x 30mm in size and simply plug into sockets so are easy to change, although you need a firm grip to move them. Try swapping them and the fault should move with the relay.
On mine, one relay was sticking open so a sharp tap when operating the tilt switch was enough to to get it working. I think the relays are fairly standard car type units.
