Hyd cylinder piston seals, or pilot check valve seals in pump, Merc does not service pump, they like to sell new ones.

Re: trim and tilt

Bad valve in your pump. Under pressure, it does exactly what its supposed to. When power is off, oil flows back and drops unit.<br /><br />You can get a used one for about $150. A new Merc one will run you north of $400.<br /><br />If you decide to replace new, try these guys. They have quality parts for less than the dealer: http://www.arcomarine.com/
