My 150 is stuck in the up position. I can hear the motor / pump when pushing cowling switch up and down. I have done the typical troubleshooting of checking the resevoir, swapped out relays, reseated swith connectors (red, blue, grenn etc). The boats on a lift and access to motor is tough. I will drop the manual release but would rather exhaust all options to determine if motor or actuator assembly is bad first before hauling it out for an R & R of components Any suggestions would be greatly apreciated.
