My lower unit hydraulic unit is not bolted to anything. It looks like there was a casing that has rotted out. It's not easy to move it, but I am planning to drop tomorrow for the season. Is this a big deal? Could I rig up a small encasing to keep it in place and be ok? It is in the rear starboard side in the very back. Any suggestions would be much appreciated. It says something like SAE J1171 on the unit itself. 99 Sea Ray 210 with a 5.0 Merc.
