More about this item

Mercury Marine 8M0217764 Hub Kits

The Mercury Prop Hub Kit HD (Part Number 8M0217764) is a genuine OEM heavy-duty hub kit designed for use with compatible Mercury propellers. The hub kit is the rubber and hardware assembly that sits between the propeller and the gearcase, transmitting power from the shaft to the prop while also acting as a sacrificial buffer that absorbs shock loads before they reach the gearcase.

The HD designation indicates this is the heavy-duty version, built for higher-torque applications and engines where standard hub kits may not hold up under sustained load. If you are running a larger engine or a high-performance application, the HD kit is the correct choice over the standard version.

Hub kits are a routine replacement item. They wear over time from normal use and should be replaced any time a propeller is removed for service or after a strike. A worn or slipping hub shows up as RPM climbing without a corresponding increase in boat speed, which is a clear sign the hub is no longer transferring power efficiently.

Confirm compatibility with your specific Mercury propeller model and engine before ordering, as hub kit fitment varies across propeller series and gearcase configurations.
