My outdrive hydraulic pump will work to lower the outdrive, but will not work to lift it. Occasionaly, when I hit the up switch, it will engauge, but quickly stopps.

Here is a link to the OEM service manual online.
Go to section 1C (troubleshooting) complete details on checking the system.

Your problem could be anywhere from a dirty connection to a bad solenoid, but the chart will pinpoint it accuratly and quickly if you follow the steps.
