Anchor Bushing, Inc. 1 3/4" To 1 3/8" Nylon (Nb12)

The shock of shifting is absorbed by a 1 3/4" to 1 3/8" NYLON (NB12) bushing inside an outboard propeller hub. Should you hit something, the bushing acts as a "breakaway," allowing the prop to spin and safeguarding drive train components such as gears. There is usually enough friction left to operate at low RPMs - sort of like a "go home" mode. With high RPM, a spinning hub seems like a power loss. At high RPM, the prop will almost certainly slip. It also absorbs power from the engine to the boat's propeller. It accomplishes this by transferring spinning power from the front to the back. Torque will transfer from the transmission to the boat's differential, which then sends torque to the propeller, allowing the vehicle to move. You can't drive without torque transfer between the various components. The bushings absorb vibrations and allow two independent sections to move without causing damage to drivetrain components.

Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.

We are happy to help you find the right contact or documentation, but we cannot decide outcomes or intervene in claim resolutions. For guidance, email cs@qualityboatparts.com.
