I pulled my 1981 SeaRay SRV 225 with a Mercruiser 260 out of the water after a full day of boating and trimmed the sterndrive all the way up. When I got to the wash and pushed the down button it didnt' move. The hydraulic motor was making noise like usual but nothing was happening. The sterndrive # is 5924220 in case that helps. Any ideas would be greatly appreciated.
