2006 44 DB sea water leak

[JNMNL]

At cruise speeds between 19-23 kts I am getting sea water leaking into the bilge between the upper and lower hull seam where they mate at the transom on each side. At speeds above 23kts the boat rides higher on plane and the slipstream of sea water bypasses the flared transom. Anyone else experience this problem?

Caulk.

Sounds like the hull/deck joint and/or the rubrail screws are leaking- at least.
Pull the rubrail screws and re-bed them, and run a bead of caulk (clear silicone would be my choice) along the top and bottom of the rubrail. That's the "quick" fix.

If you're really motivated to do the job "right", you need to pull and re-bed the rubrail.

I've seen some poorly made boats where this "shoebox" joint (as it's called) was very poorly fitting- with a large gap on the underside between the hull and inner liner that would scoop a bunch of water as you're describing. Have you taken a look at the underside of the rubrail on the hullsides near the transom to see if there's a visible gap? It could be (in a severe case) that the joint has come apart...

I wouldn't go cauling this myself.......I'd call Sea Ray or the selling dealer.....The boat is way too new......this is definitely something I'd want the factory rep to be involved with.

Didn't notice it was a boat under warranty.

TBNPR you were right on. Took my dealer mechanic out for a spin and he observed water coming in while underway. THe water is in fct coming from the so called shoe box joint. Searay is scheduled to recaulk the rub rail and splash rails are going to be installed.
