85mm 12-Tooth Retaining Ring Wrench Head for Older Mercury and Mariner

Remove and install the bearing carrier retaining ring on older Mercury and Mariner outboards where the 87mm AMT0032-002 head is too large. The AMT0032-0021 is an 85mm, 12-tooth retaining ring wrench head that mounts to the Retaining Ring Wrench Handle (AMT0031), which slips over the prop shaft and takes a 1/2" square drive. The patent-pending spline drive carries the load through the splines, not the bolts. Nickel-plated steel for corrosion and wear resistance. Backed by the Marine Tech Tools lifetime warranty.
