I have the tilt and trim that is outside the transom bracket. Have replaced the motor, resovoir and the valve body. Have determined that the culprit is the valve in the starboard cylinder. Any other ideas? Seek a used valve or cylinder. This would be the one that does not house the sending unit. Is the valve available from anywhere? Thanks This is a 1975 Johnson 70 HP. Runs like a champ just need a little assist finding valve for the tilt trim cylinder.....HELP?????
