Attwood Lock-N-Stow Outboard Motor Support – Select Mercury Outboards (10108)
Keep your Mercury outboard motor secure and protected during trailering with the Attwood Lock-N-Stow outboard support. Unlike a traditional transom saver, the Lock-N-Stow locks the motor in the forward-tilted position — the way Mercury recommends trailering — rather than tying the lower unit back to the trailer. This eliminates the excessive pressure on hydraulic trim seals that a conventional transom saver can cause, and prevents the scuff marks that come from lower unit contact with a support bar.
The compact, low-profile design stores easily in virtually any boat compartment when not in use. Constructed of black powder-coated steel with stainless steel pins for corrosion resistance in marine environments. Designed specifically for select Mercury outboard models — confirm compatibility with your engine before ordering.

Parts Desk Insights
The Lock-N-Stow is the right solution specifically for Mercury outboard owners whose engine is designed to trailer in the forward-tilted position. Mercury’s recommended trailering method for many of their motors is to lock the engine forward — not to rest it on a transom saver bar — because the hydraulic trim system on these motors is not designed to bear the motor’s weight through the tilt mechanism during transport. A conventional transom saver used on these engines can put undue stress on the trim seals and lead to premature failure. If you’re unsure whether your Mercury outboard uses the forward-lock trailering method, check your engine’s owner manual or the Mercury documentation for your model year. The 10108 and 10107 models cover different Mercury engine configurations — confirm which part number fits your specific motor before ordering.
