Need help with a OMC Stern Drive that will no tilt up. (m/n: 983486, 120hp, 2.5L, 4 cyl) Both solenoids were replaced and both work. When I hit the motor the drive will work intermittantly. I assume the motor brushes or contact internal to the motor is the problem. Can this motor be serviced with out removing the lower drive? Can the brushes be replaced with out removing the motor? Does any one have any advice on this problem?<br /><br />Steve
