I'm bumbling my way through setting up an 18hp Tohatsu on an old Haines 565L. The main 125 Mercury has let me down a few times so I'd like to venture further offshore with more confidence.
I'm assuming a nylon base plate on the outside of the transom will be a good idea to secure the mount and damp vibrations. Can anyone please advise
A. If it would be okay to use a nylon cutting board, say 5mm thick, and
B. Whether I should also put a base plate under the inside lock nuts?
To complicate things, the top two bolts will have to go through the side of the built in bait box as well as the transom.
Thanks for any ideas!
