I have a 2000 XR6. I need the seal for the two power trim cylinders (the starboard one is leaking) and the tool to remove the cap and reinstall it. Can you guide me to the correct part?
Unfortunately this seal is not to the trim system. It is just to the lower unit. You will need to contact Mercury on the seal for the trim cylinders.
