Description
SIERRA Hurth Transmission Filter Kit – 18-7964-1 is a transmission-fluid filter service kit for MerCruiser V8 inboards equipped with Hurth 630 or 800 down-angle and V-drive transmissions. It replaces several MerCruiser transmission-filter numbers and is intended for scheduled gearbox-fluid/filter maintenance.
This is a transmission filter kit, not an engine-oil filter. Confirm the transmission model before ordering, since Hurth/ZF marine gearboxes use different internal filters and sealing arrangements across model families.
