99mm 12-Tooth Retaining Ring Wrench Head, Yamaha 225–300hp – YB-06677

Remove and install the bearing carrier retaining ring on Yamaha 225–300hp outboards from 2010 on and the Suzuki DF350. The AMT0032-007 is a 99mm, 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.
