After going under in fresh water my 85HP Yamaha engine has been dried out and carbs cleaned and it works but the tilt and trim does not. There is an ominous click when I turn the switch (like a car starter motor jammed). I can not get to the hydraulic motor as the engine is stuck down and seems to cover two of the screws on top of the motor. One electrical expert thought it was a relay and replaced this but it still clicks in the engine when turned on. How do you release preesure to get the engine up and out of the way in order to look at the hydraulic pump? Any suggestions to help out? DINFISHER
