A transmission coupling connects the marine transmission output flange to the propeller shaft. It transfers engine torque to the shaft while maintaining proper alignment and secure mechanical connection between components.

2. Why are Buck Algonquin transmission couplings commonly used in marine applications?

Buck Algonquin couplings are made from ductile iron and machined to precise standards, making them strong, durable, and suitable for high-load marine propulsion systems. Many models also feature corrosion-resistant finishes for harsh marine environments.

3. What types of Buck Algonquin transmission couplings are available?

Common types include:

Solid couplings
Split couplings (for easier installation and removal)
Standard taper couplings
Reverse taper couplings

Each type is designed to match different shaft configurations and installation needs.

4. How do I choose the correct transmission coupling for my boat?

To select the correct coupling, you should:

Identify your transmission manufacturer and model.
Confirm your shaft diameter and taper type.
Verify flange size and bolt pattern.
Check compatibility charts or consult a marine parts specialist.

Proper sizing is critical to avoid vibration and drivetrain damage.

What shaft sizes do Buck Algonquin transmission couplings support?
