My son just got off the phone with me and he has a problem with the outdrive lifting system on a mercruiser 140 I/O. He raised it to move the boat and now it won't go back down. The solenoids seem to be working ok, the motor seems to be running but in won't go down. His big weekend fishing in Cape Cod Bay with the boys is going down the tubes. Is there a bleeder system that can be used to lower the unit??? Any immediate help would be appreciated. Thanks Roger

What year outdrive and trim-n-tilt unit is it? Chances are, you can lower the outdrive by disconnecting it from the rams (should be e-clips and pins at each ram) but that won't help when you need to trim it or lift it again.
There should be an electric motor right on the pump. You can remove it from the pump easily, open it and clean the armature. Make sure the brushes are wired. Put it back together and on the pump, and try it.
If the motor is working ok, check to see that oil is moving to the rams. Just disconnect the oil lines, and run the motor to see if it is. If you don't want the mess of the flowing oil, disconnect the rams from the outdrive, run the pump and see if the rams are working.

Donn, thanks for the quick response. The boat is an old 84 sea ray, it has a new. 1999 140 horse engine, with an alpha 1 outdrive,original from 1984. If he removes the lines can he push down the outdrive and will it stay down. The hydrolic pump works as it raised the outdrive, it won't LOWER the unit. I assumed that there must be a way to lower the outdrive as you can with a small hydrolic stand jack. You just loosen the bleeder valve and down it comes, save the fluid and put it back in. If we can find a way to get in daown and make sure that it stays down then all will be OK until I can have a looksee and fix it. Do you have a Phone # that I can reach you at?????? Thanks Roger

Roger...the phone will do no good. I'm working outside today, and won't hear it. Use the email address in my profile. I check email whenever I take a break.
There's a bunch of Alpha-1 owners on the web, by the way. Just Google Mercruiser Alpha-1.
You know that the pump and rams worked once, when it raised the outdrive. Lifting the drive and moving the boat could have broken a wire to one of the brushes in the pump's motor, or could have been the final corroding of the armature.
You don't need to bleed the hydraulics to lower the drive manually. Pop the e-clip and pull the pin where each ram connects to the drive. Once they're disconnected, lower the drive. Then run the pump to see that each ram is functioning.
Last tip...check to make sure there isn't a mechanical latch that may have engaged...like those on an outboard, locking the motor in the up position. I've seen these added to Alpha-1's that are frequently trailered.

Many thanks to those who responded to my call for help. Especially to Donn. The problem was everextention of the rams. The solution was to remove them to a place where we could exert enough compressive pressure to free them. New fluid, reassembly and the kids were off for some of the best fishing off the Billingsgate Shoals in Cape Cod Bay. Thanks again forumites. Roger
