Attwood 10107 Lock N' Stow Outboard Trailering Lock, Fits Mercury 200 OptiMax, 255 OptiMax, 225 EFI, 250 EFI

The Attwood 10107 Lock N' Stow secures an outboard motor in a forward position during trailering, 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, so it eliminates scuff marks on the boat or trailer finish and avoids placing excessive pressure on the engine's hydraulic seals. The lock is built with an aluminum body finished in a black powder coat for corrosion resistance, and uses stainless steel pins for long-term durability, including in salt water use. Its compact design allows it to be stored easily in nearly any boat compartment when not in use. The Attwood 10107 is sized for larger outboards and fits Mercury 200 OptiMax, 255 OptiMax, 225-HP EFI, and 250-HP EFI engines, making it a practical trailering accessory for boat owners running these Mercury outboard models.
