Noticed leakage at fitting on lift cylinder, when I tried to tighten line nut,the fitting it threads into just fell apart,applied very little pressure. The fitting is secured to cylinder with a metal band,does not appear to be removable ,other than cutting band. If band is removed could a fitting be threaded directly into cylinder? Probably will need to replace cylinder, looks like a major project. I have a manual, tried to drive rods out,as covered in manual. They are extremely tight! It has been primarily a salt water boat , with corrosion as expected.
