aLL OF A SUDDEN, THE POWER TRIM/TILT DOESN'T WORK ON MY 1993 75 HP MARINER OUTBOARD. THE UNIT LOOKS BRAND NEW, NO LEAKS OF ANY KIND. THE ELECTRIC MOTOR RUNS BOTH DIRECTIONS, BUT THE BOAT ENGINE DOES NOT MOVE. i CHECKED THE RESERVOIR AND HAVE PLENTY OF FLUID. i LOOKED AT A PARTS BREAKDOWN AND THERE IS A VALVE KIT AVAILABLE FOR THIS POWER TRIM.... DOES THIS SOUND LIKE A POSSIBLE FIX? AND IS IT RELATIVELY EASY TO INSTALL?
