Performance & Practical Benefits
With the steering locked in place, the engines stay put instead of drifting toward each other on bumps or corners. It keeps the tie-bar system from taking unnecessary stress and gives you peace of mind on longer tows. It also cuts back on the wobble and clunking noises you sometimes hear when engines aren’t secured.

Why Buy OEM
OEM parts are built for the exact geometry of Mercury JPO rigs, so the lock fits correctly and holds securely. You’re not fighting sloppy fitment or worrying about damaging anything during transport.
