Like many, I noticed an inordinate amount of water leaking down through the rear rear hatch area due to the poorly designed deck and scuppers. Leaking was especially noticeable when I wash downed the boat after her maiden voyage with my wife. Water pools near the so-called scuppers and does not drain overboard unless there's a substantial amount of water near them. The rest of the water pools in both areas, eventually seeping down through the rear hatch into the bilge area - over batteries and other electrical components. Since I'm a freediver, it's not uncommon to get the deck very wet through the day. I realize sealing the deck 100% may not be possible, but somewhere in the 90% should be possible. Crappy design! Whaler should come out with aftermarket seals to eliminate the problem and/or scupper modification kits for owners stuck with the older models. The upper deck piece above the main hatch was sealed well by the previous owner because he installed a bait tank on it.

I took Jollyrog's advice and resealed/replaced the poorly sealed rear deck plates and motor-well access hatch. That will help, but it appears the only real solution after resealing the hatch with some home depot stuff is to install smaller deck drains (that drain into the motor-well) in the lower most portion of the indentation in front of the vertically mounted factory scuppers.

Like others, I also had leaking through the poorly installed ports. I removed the inside plates and screws, applied silicone to the gap between the window and boat, other areas - seems to have worked.

Windshield wipers leaking - that's another project!

Geeze! I guess they were so caught up on making a boat full of foam that they forgot about other details that make a quality boat!

Yes, she rides great and has new 300 Verados...But I have a bucket list of projects, mostly weather proofing, that should not be an issue with a so-called well made boat...
