The Scotty 139 Marine Grade Phone Holder is a rugged, adjustable device mount built for use on the water. Designed to hold smartphones and devices between 2-3/4" and 3-3/4" wide, it features dual ball-joints for infinite positioning flexibility and a bottom opening for charging access while the device is mounted. Includes a post mount, track mount, and 7/8"–1-1/4" rail mount — ready to install on a wide range of boat configurations right out of the box.
Marine-Grade Construction
Built to handle the vibration, moisture, and UV exposure of regular on-water use. Materials and finish are selected for durability in harsh marine environments, resisting corrosion and UV degradation over time.
Dual Ball-Joint Positioning
Two independent ball-joints allow the holder to be positioned at virtually any angle — tilt, swivel, and rotate to get the perfect viewing angle regardless of helm layout or sun position. Lock down with the easy-grip T-knob once positioned.
Width-Adjustable Grip
The spring-loaded, width-adjustable grip accommodates devices from 2-3/4" to 3-3/4" wide, covering most current smartphones with or without a slim case. The easy-grip T-knob provides secure, tool-free width adjustment.
Charge While Mounted
An opening at the base of the holder provides unobstructed access to the device’s charging port, so you can run navigation or fishing apps continuously without removing the phone from the mount.
What’s Included
The 139 ships with three mounting options: a post mount (compatible with all Scotty post mounting systems), a track mount, and a 7/8"–1-1/4" rail mount — giving you flexibility to install on gunwales, rails, tracks, or existing Scotty post bases.
Parts Desk Insights
- Best Use Case: Best suited for anglers and boaters who want a secure, adjustable phone mount at the helm or console for running navigation apps, chartplotter mirrors, or fishing apps like Navionics or Humminbird FishSmart. The included rail and track mounts make it a versatile fit for most boat types without additional hardware.
- Device Width: Fits devices 2-3/4" to 3-3/4" wide. Most modern smartphones in a slim case fall within this range, but thick or rugged cases may push the device outside the grip range — measure your cased device width before ordering.
- Scotty Post Compatibility: The included post mount is compatible with all Scotty post mounting bases. If your boat already has a Scotty mounting base installed, the 139 drops straight in. See the Scotty Coaming/Gunnel Clamp Mount for a compatible base option.
- Rail Mount Range: The included rail mount fits 7/8" to 1-1/4" diameter rails, covering most standard stainless and aluminum boat rails.
- Weight Note: The 139 is a lightweight plastic mount — not intended for tablets or larger devices outside the specified width range.
