Humminbird IDMK RM A13 In-Dash Mounting Kit f/APEX® 13 — Product description

Seamless Integration for Your APEX 13 at the Helm

Imagine powering through rough waters or scanning for that perfect cast without distractions from a wobbly display. The IDMK RM A13 delivers exactly that—a robust in-dash mounting kit tailored for APEX 13 units. Designed with boaters in mind, this rear-mounted bracket setup tucks your control head neatly behind the dash, creating a streamlined helm that withstands vibrations, splashes, and daily marine abuse. Anglers chasing trophy fish or navigators plotting offshore routes appreciate how it elevates both functionality and style.

Built to Last in Harsh Marine Conditions

  • Precision Aluminum Construction: Crafted from high-grade aluminum, the reinforced bracket resists corrosion and flexing, ensuring your APEX 13 stays rock-solid even on choppy days.
  • Stainless Steel Hardware: Every bolt and screw is marine-grade stainless steel, fighting rust and providing superior holding power for long-term reliability.
  • Silver Finish: Matches modern console aesthetics, blending seamlessly with gelcoat or carbon fiber dashes for a professional, factory-fresh appearance.
  • Rear-Mount Design: Mounts from behind for minimal front-panel visibility, perfect for flush or semi-recessed installs without bulky protrusions.

Why Boaters Trust This Mounting Solution

Unlike generic brackets that loosen over time, this kit prioritizes security and simplicity. It locks your APEX 13 control head firmly to the surface, preventing shifts during high-speed runs or heavy trolling motor use. The result? Crystal-clear sonar reads, responsive charts, and uninterrupted MEGA Imaging without screen glare or movement. Tournament pros and weekend warriors alike report easier wiring runs and a clutter-free cockpit, making helm access intuitive even in low light.

Key advantages include reduced wind resistance from a low-profile setup and compatibility with popular dash cutouts, saving hours on custom fabrication. It's the upgrade that turns a good install into a great one.

Effortless Installation Tips for DIY Enthusiasts

Setting up the IDMK RM A13 requires basic tools like a drill, screwdriver, and measuring tape—no specialized gear needed. Start by tracing the APEX 13 template on your dash, then secure the bracket from the rear with included hardware. Pro tip: Use thread locker on screws for extra vibration resistance in high-performance bass boats. Double-check cable routing to avoid pinches, and test-fit before final tightening. Most installs wrap up in under an hour, leaving more time on the water.

  • Verify dash thickness compatibility (typically 1/8" to 1/4" panels).
  • Pair with grommets for clean cable passthroughs.
  • Apply marine sealant around edges for watertight seals.

Perfect Fit for APEX 13 Series

This kit aligns flawlessly with every APEX 13 variant, from base chartplotters to advanced sonar-equipped models. Whether you're running dual-screen setups or integrating with Minn Kota trolling motors, it supports the full range without modifications. Boaters upgrading from older Helix or Solix units find it a straightforward swap, maintaining that signature Humminbird ergonomics.
