Aluminum 1.5 in Ball Mount 14.76 in Extended Dual Arm - Marine Mount

In this review of the Aluminum 1.5 in Ball Mount, the bottom line is simple: if you need a durable, adjustable mounting solution for a fish finder, tablet or chartplotter on a boat, this mount delivers stability and corrosion resistance where it matters most. Built from a marine-grade aluminum alloy with a long 14.76 in dual arm and a high-pressure molded TPU 1.5 in ball, the unit is aimed at boaters and anglers who want a secure, AMPS-compatible mounting point that stays rock solid in harsh, wet conditions.

Key Features

• Rugged marine-grade aluminum: One-piece die-cast aluminum construction provides long-term corrosion resistance and a stable base for electronics exposed to saltwater and weather.
• 14.76 in extended dual arm: The long dual-rod arm brings devices closer and allows more flexible placement and reach on consoles or flat decks.
• Four 360-degree pivot points: Multiple pivot joints let you position screens at optimal viewing angles even in tight or awkward spaces.
• Oversized wingnut: A widened wingnut gives better grip for quick adjustments and secure locking while wearing gloves or when wet.
• High-pressure molded TPU ball: The 1.5 in C-size TPU ball resists deformation and aging, offering a firmer connection and compatibility with common 1.5 in accessories.
• AMPS hole pattern: Pre-drilled AMPS-compatible mounting plate works with many fish finders, small chartplotters and tablet holders for a bolted secure fit.

Who It's For

The mount is best suited for recreational anglers, small-boat captains and mariners who need a reliable, corrosion-resistant mounting solution for electronics such as fish finders and small tablets. Its extended reach and robust construction make it especially useful for center consoles, kayaks with flat mounting surfaces and workboats that see heavy use.

It is less appropriate for users who need ultra-lightweight plastic mounts for occasional freshwater use or those who require an integrated power or cable-management system; this product focuses on mechanical strength and flexible positioning rather than accessory integration.

Pros & Cons

Pros

• Sturdy die-cast marine-grade aluminum gives long-term corrosion resistance and solid support.
• Extended 14.76 in dual arm and four pivot points provide excellent placement flexibility.
• 1.5 in TPU ball and AMPS plate ensure broad compatibility with common marine electronics.
• Large wingnut enables quick, gloved adjustments and secure locking.

Cons

• Heavier and more substantial than basic plastic mounts, which may be overkill for light, occasional use.
• No built-in cable management or power routing; additional hardware may be needed for tidy installs.
