SeaSucker Dry Box

This dry box is perfect for storing your valuables on your boat. The box is waterproof so your wallet, cell phone, camera, and other small valuables stay dry around wet passengers, or in the rain. The lid has 2 clips that prevent the box from opening unexpectedly. The clear, hard plastic construction lets you see what's inside without opening the lid and you don't have to worry about your valuables getting crushed. The dry box also includes a lanyard that makes it easy to carry to and from your boat without removing the contents.

SeaSucker Vacuum Cup

The dry box is quick and easy to mount. To install the box make sure the mounting surface is clean and place the vacuum cup on your boat's dash, or any other non-porous surface then press the pump several times until the orange band disappears. To break the seal and remove the box from your boat simply pull the T-shaped tab up and towards the center of the cup. As suction decreases over time the plunger will extend from the cup. When the orange indicator band shows simply re-pump the plunger.

Video Transcript for SeaSucker Marine Boat Accessories - Dry Box - 302-5501 Review

Today we're going to be taking a look at the Seasucker drive box. This drive box would be a great addition to your boat. It's big enough for your wallet, cell phone, camera and many other items. It's going to keep those items dry. It seals tight to keep out water. You're going to have two clips that snap tight to keep the lid closed. I do want to point out that on this side right here, it's got a hole that matches up so the lid is lockable with a padlock.

The padlock is sold separately. Those lock holes have a diameter of 3/16". Really nice open design. Plenty of room to get your gear in there. It's going to hold firmly to your dash or other horizontal surface with a powerful 4-1/2" vacuum mount.

It's going to feature a pull rating of 120 lbs. The unit can be installed and removed very quickly and easily. The available space inside the box: It's going to have about 7-1/2" of space at the bottom, 3-1/2" tall. That's with the lid closed, and about 3-1/2" wide at the bottom. The opening itself, going edge to edge in this direction, that opening is going to measure about 7-7/8". Going this direction, that opening is going to measure about 3-13/16th" or 3-7/8th", right in that area.

Once you have this mounted, from the mounting surface to the furthermost point of the box, it's going to be about 6". It does come with waterproof lubricant to keep the components of the Seasucker working properly. It's made in the USA. When you're ready to install it, you need to make sure that the surface area, as well as the seal right here, is nice and clean. Place it on there, use just a little bit of pressure and then you just pump this plunger until the orange disappears. Once the orange disappears, that's going to let you know that the unit is seated correctly and it's ready to be used. When you're ready to release it, it's got these easy-grip pull tabs that you can just lift up on.

That would break the seal and allow the unit to be removed from the installation surface. That's going to do it for today's look at the Seasucker drive box.
