Hello all, so we tested the boat, everything running great, dropped it in the water the next morning, drive went down, then nothing, put boat in reverse drive floats up, pulled back out, the drive has no restrictions up and down, nothing leaking, resivor is full, no water, pump motor is running.

This is the trim/tilt that is attached to the transom shield and is all on the back of the boat. Volvo says this is a sealed unit no adjustments to make.

has anyone ever had this problem before?
