SEI Marine ProductsCompatible with - Mercury Mariner 20" Driveshaft 45-881938 200 225 250 HP 2 Stroke 3.0L V6

I got shafted. Seriously good quality, had great temperament on the threaded end. Fit n finish are perfect and the price is unmatched. If you have trouble finding exactly the shaft you need, call SEI with your serial number and they'll get you the exact match that you need.
