TACO Marine Grand Slam 312 Center Rigger Mount, For 1-1/2 in Poles, Up to 2 in Hard Tops, SS316 Arms

Overview

The TACO Marine GS-312 is a Grand Slam 312 center rigger mount for offshore trolling setups that need a center line run from a hardtop, T-top, flybridge, or tower without climbing above the deck. It is built for 1-1/2 inch diameter center rigger poles and hardtops up to 2 inches thick, making it a practical fit for many large center console boats rigged for long baits and shotgun presentations.

The mount uses a rotating crank handle so the center rigger can be raised and lowered from underneath the hardtop. For crews fishing offshore, that means cleaner deployment and adjustment while staying on the deck, especially when running multiple outrigger lines and keeping the center rigger line farther back from the boat.

Key features

• Rotating crank handle raises and lowers the center rigger from below the hardtop, so crew members do not need to climb onto the top, flybridge, or tower during normal deployment.
• Fits 1-1/2 inch diameter center rigger poles for offshore trolling layouts that use a dedicated center line.
• Accommodates hardtops up to 2 inches thick, with a fixed straight-back mount position for center rigger use.
• Large gusset support helps the mount handle long runs at high speed when the center rigger is installed and properly secured.
• Twist and lock retaining pins help hold the pole in place while still allowing two hands for installation and removal.
• Type 316 stainless steel arms and crank handles are paired with an anodized aluminum housing and rotator for exposed saltwater use.
• 4 inch by 6 inch mounting base gives the installer a clear footprint for planning the mounting location.
• Sold individually, with a listed unit weight of 10 lbs and a three-year limited warranty.

Installation and fit

Before mounting, confirm that the hardtop, arch, canvas top frame, or supporting structure can carry the load from the center rigger base and pole. The installation requires a 3-1/8 inch center hole, accurate bolt-hole placement, stainless steel mounting hardware, nylon washers where stainless hardware meets the anodized aluminum base, and marine-grade sealant around the mounting surface to help manage water intrusion.

The GS-312 should be installed where the crank can be reached comfortably from the deck and where the pole has enough clearance to move through its vertical range. The center rigger is intended for up and down movement rather than side-to-side adjustment, so alignment during installation matters.

Use on board

This mount suits offshore anglers who want to run a shotgun bait or lure behind the main spread while keeping the center rigger controls accessible from below the top. In typical trolling use, the center rigger line runs farther back and away from the outrigger lines, helping keep the spread organized when multiple baits are in the water.

It is a strong match for center console fishing boats where the crew needs the reach of a center rigger but does not want routine deployment to involve climbing onto a leaning post, T-top, tower, or flybridge.

Materials and care

The Type 316 stainless steel and anodized aluminum construction is appropriate for a marine environment, but the mount should still be rinsed with fresh water after saltwater use and checked regularly for smooth crank movement, secure retaining pins, and tight mounting hardware. A periodic inspection is especially important on boats that troll offshore at speed or keep the rigger installed for long periods.
