Product Description
Shimano Moocher 4000GT Compatible Drag Knob (MCR0065 Replacement)
Enhance your downrigger fishing experience with this premium 3D-printed drag knob, engineered specifically for the Shimano 4000GT Moocher. This high-performance replacement for part #MCR0065 is designed to solve the common failures of vintage components, offering a more robust and tactile interface for managing heavy-hitting salmon and saltwater game.
Constructed from an industrial-grade tough polymer, this knob is built to withstand the rigors of high-drag pressure and environmental exposure.

Maintenance & Performance Tips
To ensure your drag system remains silky smooth under the heavy load of a trolling spread, proper lubrication is essential. We strongly recommend the following:
-
Deuthlon Reel Grease: Apply to the internal threads of the 8mm nut and the drag washer stack for maximum heat resistance and water displacement.
-
Deuthlon Reel Oil: Use on the handle bearings and spool shaft for high-speed performance and corrosion protection.
