    That's a metal to metal joining surface... yes, it will leak for awhile but will eventually seal with marine debris. Or, you can drop the unit 1/4" or so and squirt in the sealer mentioned below, then tighten it back up again.

    Originally known as OMC Adhesive is now Bombardier 3M Product #847 and may be listed as Scotchgrip 847, part number 776964 or "Loctite #518".
