Outboard Gearbox Reconditioning

We Re-Manufacture outboard motor and stern drive gearboxes and gear cases keeping common Johnson, Evinrude, Mercury & Mercruiser exchange options in stock.  If we don’t have your gearbox available as an exchange we will Re-Manufacture yours in good time.  We have invested in cleaning machines: Hot Spray Washer, Bead Blaster, Ultrasonic bath and a Down draft bench as well as specialist tools to perform correct gear case assembly.

If your outboard gear case has any sign of metal on the magnets, water in the oil, jumps out of gear when travelling or has fishing line around the propeller shaft – you need our services!
