Trim/Tilt in Merk 1150
 

The pump assembly has a release valve that can be opened and this should
allow the motor to drop down. As I recall it is either a 3/8th or 7/16 hex
head. After getting the motor in the down position close the valve.
Topping off the oil revision, run the motor up and down several tummies any
you MAY be back in business.
