Attwood 10108 Lock N' Stow Outboard Motor Trailering Lock - Fits Mercury 135, 150, 175 OptiMax and 75-200 HP EFI Engines

The Attwood 10108 Lock N' Stow is a trailering lock that secures an outboard motor in a forward position while towing, greatly reducing the risk of road shock damaging the engine. Unlike devices that tie the engine's lower unit directly to the trailer, the Lock N' Stow does not restrain the lower unit, which eliminates scuff marks on the engine and trailer and removes the risk of excessive pressure being placed on hydraulic seals during transport.

Construction is black powder-coated steel for corrosion resistance and durability, paired with stainless steel pins for long-term reliability in marine environments. The compact design allows the lock to be stored easily in nearly any boat compartment when not in use, so it is always on hand before towing. It is recommended for use in salt water applications and is built to handle outboard engines up to 200 horsepower.

The Attwood 10108 is designed to fit Mercury 135 OptiMax, 150 OptiMax, and 175 OptiMax outboards, as well as Mercury 75 HP to 200 HP EFI outboard motors.
