Sea Swivel Sea Secure Titanium Security Bolt

The Sea Swivel Sea Secure (MPN SEA-SECURE-PPM) is a titanium anti-theft security bolt designed specifically for the compatible flagship trolling motor's deck-mount bracket. It replaces the standard mounting bolt with a uniquely-keyed lockable bolt that requires a matching key to install or remove. Without the key, even a thief with a full toolbox can't lift the motor off your bow deck. For owners of flagship trolling motors who store the boat in a marina slip, at a club, or in a public boat yard, this is the simplest, lowest-cost insurance against theft you can install.

Why trolling motor theft is real. A flagship trolling motor is a four-figure piece of hardware that sits exposed on the bow deck. It's quick to unbolt and lift off, and it has resale value on the secondary market. Police reports from boat yards and marinas across the southeast and Great Lakes regions consistently rank trolling motor theft among the top three on-water property crimes. Insurance often covers it, but the deductible plus the downtime while you wait for a replacement adds up to weeks of lost fishing. The Sea Secure prevents the theft entirely by making the bolt unremovable without the matching key.

How the locking mechanism works. The Sea Secure bolt head has a proprietary keyway that matches only its included key. The keyway is not a standard hex, Torx, or Allen pattern that a thief could walk up to with a multi-bit driver. The keyway is unique to Sea Swivel and the matching key ships with the bolt. To install the bolt, you set it in the deck mount and turn with the key. To remove, you do the reverse. Without the key, no commonly-carried tool can engage the bolt head.

Titanium construction. The bolt is machined from marine-grade titanium, not stainless steel or aluminum. Titanium has roughly twice the strength-to-weight of stainless and is essentially immune to saltwater corrosion. The bolt will not seize in the deck mount over years of exposure, will not pit or stain, and will not weaken from the constant marine environment. The keyway machining is precise enough that the key engagement remains positive after thousands of insertions over the bolt's lifetime.

The compatible flagship trolling motor-specific design. This SEA-SECURE-PPM variant is sized for the compatible flagship trolling motor's deck-mount bolt pattern. The thread pitch, bolt length, and head geometry all match the factory-installed bolt that the motor ships with. The replacement is direct: you remove the stock bolt with a normal wrench, set the Sea Secure bolt in its place, and tighten with the included key. Total install time is a couple of minutes. The keyway head sits flush against the deck mount, so it doesn't change the visual profile of the install.

Why pay this much for a single bolt. Three reasons. First, the deductible on a stolen trolling motor claim is typically several hundred dollars, often more than the cost of this bolt. Second, your insurance premium can increase after a claim, multiplying the long-term cost. Third, and most importantly, the time spent dealing with the theft (police report, insurance paperwork, ordering a replacement, waiting weeks for delivery) costs you fishing days that money can't recover. The Sea Secure is preventive maintenance applied to property crime.

What happens if you lose the key. Sea Swivel maintains a key serial registry tied to the bolt serial. If you lose the key, you contact Sea Swivel with the bolt serial number (engraved on the head) and they ship a replacement key cut to match. Order a spare key when you buy the bolt and keep it at home as backup. Many owners also keep a spare in the boat's locked compartment, separate from the primary key kept on a keychain.
