here what my unit looks like. the big single piston was pouring out fluid and my trim motor was rusted to hell. the hardest part was getting it off the boat and motor. (saltwater motor). and when i dissembled i found some corrosion behind where the seal seats. that was a pain to clean up. then the manual release valve was seized too. i had to heat that up. i also have the selco repair book for the motor which helped a ton.
