Hello, and thanks for taking time to read this. An old timer friend , sank his boat in heavy rains at a lake nearby. Long story short, did all that was necessary to purge motor, and now she's running fine, but now ,3 days later trim/tilt system no longer working. I dont know alot about these outboard motors, I am an I/O guy myself, but trying to help him out.I believe the motor is an 2003, or 2004. He was told to open a screw in the back, which bled oil out, so he could manually raise his drive and get into the garage, which he did. Battery is brand new, and all else functioning fine, so I don't believe power is the problem. Says, all he gets is a clicking sound when trying to actuate the trim. Any schematics availible for this system, or how about a plan of attack for narrowing this one down to the culprit. Also, how to properly re- bleed this system when its working again would be helpful . Thank you for any advise you may have.
