Mercury – J-Box Stacking Plug Kit | Vertical SmartCraft Alignment | 23-8M0174363

Overview

SmartCraft networks can get messy when the boxes are scattered or mounted at odd angles. The Mercury 23-8M0174363 J-Box Stacking Plug Kit helps clean things up by letting you stack multiple J-boxes vertically so all the plugs line up on one side. It gives the rigging a more organized look and makes it easier to reach the ports without fighting cramped spaces or tangled wiring. It’s a small piece, but it makes the whole network feel tidier and easier to work around.

Performance & Practical Benefits

Stacking the J-boxes brings order to spaces that usually end up crowded and hard to navigate. With the ports lined up together, you can trace cables faster, add new devices without digging behind other components, and avoid the confusion that comes with mismatched orientations. The stacking plug keeps the boxes steady and helps the network stay easier to manage over the life of the boat.

Why Buy OEM

SmartCraft gear works best when everything fits the way Mercury intended. The OEM stacking plug lines up the boxes correctly and keeps them steady over time, something generic brackets often fail to do. With the proper fit, the network stays easier to service and more resistant to vibration and movement.

FAQ

Q1: When would I use this stacking plug kit?
If you’re adding more than one J-box and want all the ports facing the same way, this plug makes that layout possible.

Q2: Does stacking change how the SmartCraft network works?
No. It only changes the physical layout, not the electrical or digital behavior.

Q3: Is the installation complicated?
Not at all. The plug slides into place and the boxes mount as a single, aligned group.

Q4: Will stacked boxes stay secure in rough conditions?
Yes. The OEM plug holds them steady, even in high-vibration areas.

Q5: Does stacking help with troubleshooting?
Definitely. With the ports all facing the same direction, it’s quicker to follow wires and check connections.
