What this mount is

The Shakespeare 4187 is a stainless-steel ratchet mount built for marine GPS units. Its four-way ratchet design allows deck or side mounting so anglers can position the display where it is most visible. The quick-action handle lets you adjust or remove the unit without tools. Standard 1-14 threading fits compatible GPS brackets directly.

The spec that decides fit

The mount uses a standard 1-14 thread, so it only works with GPS brackets that share that thread pattern. If your device uses a different thread size or a proprietary base, this mount will not attach. The 9/32 cable feed-through hole also limits the connector diameter that can pass through cleanly.

Capacity and headroom

The stainless construction resists corrosion in saltwater environments and handles the vibration of a running boat. The 5/16 bolt holes on 3 x 1-1/2 centres provide a secure footprint for typical deck thicknesses. It is not suited for overhead mounting or for brackets heavier than the ratchet mechanism is designed to lock.

Questions about this item

What does the standard 1-14 thread mean for attaching my GPS antenna?

The 1-14 thread is a common marine standard that lets you screw most GPS antennas or transducers directly onto the mount without an adapter.

How does the four-way ratchet design help when positioning the unit?

The ratchet mechanism locks the mount at multiple angles so you can tilt the GPS display for best visibility whether the base is on the deck or a vertical surface.

What mounting hardware do I need for the 5/16 inch bolt holes spaced 3 by 1-1/2 on centre?

Use 5/16 inch diameter bolts; the pattern has three holes arranged 1-1/2 inches apart on centre for a secure deck or side installation.
