I need to replace the seals and o rings on one of my trim cylinders (seeping fluid). I know I'll need the "special tool" for the removal of the cap but can I disasemble the trim cylinder without removing the TnT system from the motor....I don't have the means to remove the outboard from the boat so before I buy the special tool and parts, I want to make sure I can do the repair without removing the outboard from the boat....Can the seals and o-rings be replace with the motor still mounted to the boat?
