496 MAG Power Steering Pump Updates

Attention 496 MAG Base and HO engine owners!

Mercury Marine has a newly designed pump, bracket and pulley. The new parts are not interchangeable with the old, i.e. the new pump won't work with the original bracket or pulley. So if you're buying a new pump for your 496 that fits into the below serial number range, you will need a new pulley and new bracket.

This became effective October, 2025.

The new part numbers are below.
