Marine Diesel Engine Flexible Shaft Coupling.
Santa Barbara Diesel Mechanic. can install a large array of flexible shaft couplings. A marine flexible coupling fits in-between the gearbox output flange and the boat prop shaft.
The primary role of a flexible coupling is to reduce noise and vibration. There are a number of marine coupling types available. The choice of which will depend on many factors. Including engine horsepower, gearbox reduction, application, budget, space and the results required.
Some models are also able to compensate for small degrees of misalignment. We would be pleased to help with your selection, if you are not sure which product you require, please contact us.
How to select your Flexible Shaft Coupling. You will need the following details: Engine horsepower and engine speed Gearbox type and reduction ratio Gearbox flange details: Diameter of flange.
Flexible couplings.
install simply and quickly, so no cutting or machining is required. And because you don’t have to haul your boat out of the water. you can just separate the drive flanges, insert the coupling, align coupling and bolt together.

A marine engine shaft coupling is a critical component in a marine propulsion system, connecting the engine to the propeller shaft. It plays a significant role in the overall performance and reliability of a vessel. Here are the key benefits of using a marine engine shaft coupling:
1. Power Transmission
- Ensures efficient transfer of power from the engine to the propeller, enabling smooth propulsion.
2. Alignment and Misalignment Compensation
- Compensates for slight misalignments between the engine and the propeller shaft due to installation imperfections or operational conditions (e.g., hull flexing).
3. Vibration and Shock Absorption
- Dampens vibrations and absorbs shocks from the engine, reducing noise and wear on the propulsion system.
4. Protection Against Overload
- Some couplings are designed to disengage or shear in the event of an overload, protecting the engine and drivetrain components from damage.
5. Reduced Wear and Tear
- Minimizes wear on connected components by absorbing stresses and accommodating misalignment, extending the lifespan of the drivetrain.
6. Thermal Expansion Compensation
- Adjusts for thermal expansion of the shaft and engine, maintaining alignment and reducing stress on components.
7. Ease of Maintenance
- Simplifies the process of disconnecting the engine from the propeller shaft for maintenance or repairs.
8. Enhanced Safety
- Reduces the risk of catastrophic failures by providing a fail-safe mechanism in case of extreme stress or misalignment.
9. Flexibility
- Available in various types (rigid, flexible, semi-flexible) to suit different marine engine configurations and performance requirements.
10. Efficiency in Operation
- Enhances the overall operational efficiency of the vessel by ensuring smooth and reliable power transmission.
Common Types of Marine Shaft Couplings
- Rigid Couplings: Used where perfect alignment is possible.
- Flexible Couplings: Ideal for systems with alignment challenges or requiring vibration damping.
- Semi-flexible Couplings: Offer a balance between rigidity and flexibility.
By incorporating a suitable marine engine shaft coupling, operators can achieve greater reliability, efficiency, and safety in their marine propulsion systems.
