The true "only way to go" for that application is Infinity 612M.
Quote:
Co-Injection Molded Cones bond the cone to the surround during the molding process, eliminating the glue joint. Cast Polymer Baskets are used to provide a waterproof platform that also rejects UV contamination. The spider and tinsel leads are treated against moisture and UV contamination for marine applications. Poly Tweeter is used for its waterproof properties and flawless high-end extension clear out to 20kHz. This tweeter is also mounted ahead of the woofer allowing the motor structure to be sealed off from moisture.

Plus, the Blue cones will match your boat hull color.
I installed them on my boat and love them.
Oh....... they are dancing banana approved, so they are the clear winner's.
