Attwood Marine Outboard Motor Locks

Attwood Marine Outboard Motor Locks: Engineered to Protect Your Engine on the Road

When you haul your boat down the highway, your outboard motor takes a beating. Every bump, rut, and highway joint sends vibration and shock rippling through the transom — and without a dedicated locking solution, that energy can work against your engine's hydraulic seals, tilt mechanism, and lower unit. Attwood Marine, a brand with over 100 years of marine industry expertise, addresses this problem head-on with their purpose-built outboard motor locks.

The Lock N' Stow: Attwood's Signature Motor Lock Solution

Attwood's flagship entry in this category is the Lock N' Stow Outboard Motor Lock — a compact, elegantly simple device designed to hold your outboard in the forward (trailering) position while your rig is on the move. Here's what sets it apart from generic tie-down straps or improvised solutions:

• Forward-position locking: The Lock N' Stow secures the outboard motor in the forward position while trailering, greatly reducing the damaging effects of road shock on the engine and transom.
• No lower-unit tie-down: Unlike strap-based methods, it does not "tie" the engine's lower unit to the trailer, eliminating excessive pressure on hydraulic seals and preventing unsightly scuff marks on the hull or motor.
• Heavy-duty construction: Built from black powder-coated steel with stainless steel pins, the Lock N' Stow is engineered to handle the corrosive marine environment — saltwater spray, road grime, and moisture are no match for this hardware.
• Compact and storable: The small, low-profile mount can be easily stored in virtually any boat compartment when not in use, so it won't clutter your deck or storage space.
• Made in the USA: Attwood manufactures the Lock N' Stow domestically, reflecting the brand's long-standing commitment to quality control and craftsmanship.

Engine Compatibility & Fitment

Attwood offers the Lock N' Stow in configurations sized for higher-horsepower setups, with specific fitment for engines such as Mercury 200–250 HP Optimax/Optimax ProXS and 150–200 HP EFI motors. This targeted compatibility means the lock is designed to interface properly with the mounting geometry of these popular powerplants — not just bolted on as an afterthought. Always verify your engine's lower-mount bolt centerline span against the product specs before purchasing to ensure a correct fit.

Why Choose Attwood for Outboard Motor Security?

Attwood Marine has spent over a century developing hardware that boaters can trust on the water and on the road. Their products are tested to meet USCG, ABYC, and CE standards — the same rigorous benchmarks that govern safety-critical marine equipment. When it comes to protecting a significant investment like an outboard motor, that pedigree matters. The Lock N' Stow reflects the same philosophy Attwood applies across its entire catalog: solve a real problem with a durable, no-fuss solution built for the marine environment.

Whether you trailer your boat weekly or just a few times a season, an outboard motor lock is one of those small investments that pays for itself by preventing costly damage to seals, hydraulics, and finish.
