So there is air in the system, messing with the valve and getting pushed back and forth. Tried bleeding at the rams multiple times, tried pushing drives back and forth manually to relieve air, still the same problem. Anyone have any hints or suggestions for bleeding these? I ran the boat for probably 10-15 minutes straight, working the drives back and forth, with no change. Anyone ever use a vacuum-type bleeder successfully? The hoses inside the transom run pretty high, so I have a feeling that's where the air is getting trapped.
