Outboard motor brackets are important marine components used to securely mount an outboard engine to a boat. They can be useful for primary engines, kicker motors, auxiliary outboards, and certain inflatable or tender boat setups.
Choosing the correct bracket is important because the bracket must support the motor's weight, accommodate the required shaft length, and withstand the forces created while the boat is underway.
What Are Outboard Motor Brackets?
An outboard motor bracket is a mounting system that connects an outboard engine to the transom or stern of a boat. Depending on the design, a bracket may be fixed, adjustable, removable, or designed to allow the motor to be raised out of the water.
Brackets are available for different engine sizes and boat configurations, so selecting the correct model is essential.
Types of Outboard Motor Brackets
There are several common types of outboard brackets available to boat owners.
Fixed Outboard Brackets
Fixed brackets provide a permanent mounting position for an outboard motor. They are commonly used when the motor does not need to be moved vertically during normal operation.
Adjustable Brackets
Adjustable brackets allow the motor position to be changed. This can be useful when the boat owner needs flexibility in motor height or when the bracket is being used for a kicker motor.
Kicker Motor Brackets
Kicker brackets are designed for smaller auxiliary outboards. They are popular with fishing boats that use a secondary motor for trolling or backup propulsion.
Swim Platform Brackets
Some boats use specialized brackets that mount an auxiliary motor near or around a swim platform. These installations require careful consideration of clearance and weight distribution.
Inflatable Boat Motor Brackets
Certain inflatable boats and tenders use dedicated motor mounts or brackets. These products must be compatible with the boat's transom and rated for the intended motor.
Why Use an Outboard Motor Bracket?
A suitable bracket can provide several benefits:
-
Secure motor mounting
-
Improved motor positioning
-
Easier installation of auxiliary engines
-
Convenient access for maintenance
-
Greater flexibility for kicker-motor setups
-
Ability to raise or lower certain motors
-
Additional mounting options for boats with limited transom space
Choosing the Right Bracket
Several factors should be considered before buying an outboard motor bracket.
Motor Weight
The bracket must be rated to support the complete weight of the outboard. Never select a bracket solely based on engine horsepower.
Horsepower
Check the manufacturer's recommended horsepower range. A bracket designed for a small kicker motor may not be suitable for a larger outboard.
Shaft Length
The correct motor height is important for propeller positioning and performance. The bracket and motor combination should provide the appropriate shaft position relative to the boat's hull.
Transom Design
Measure the transom carefully before selecting a bracket. Different boats have different transom heights, widths, angles, and construction methods.
Material
Marine-grade aluminum and stainless steel are commonly used for outboard brackets because they offer strength and corrosion resistance.
Outboard Motor Brackets for Kicker Motors
Anglers frequently use outboard motor brackets for kicker motors. A smaller auxiliary engine can be useful for trolling, slow-speed maneuvering, and backup propulsion.
A bracket allows the kicker to remain separate from the primary outboard while providing a secure mounting position.
Before installation, ensure that the kicker motor has enough clearance from the main engine, hull, steering components, and propeller.
Adjustable Kicker Brackets
Adjustable kicker brackets are particularly useful for fishing boats because they can allow the auxiliary motor to be raised when it is not being used.
When selecting an adjustable bracket, examine the lifting mechanism, locking system, mounting plate, and weight capacity.
A robust locking mechanism is important because the bracket needs to remain securely positioned while the boat is operating.
Materials and Corrosion Resistance
Outboard brackets operate in a demanding marine environment. Saltwater, moisture, spray, and changing temperatures can contribute to corrosion.
Aluminum brackets offer a combination of strength and relatively low weight, while stainless-steel hardware can provide excellent corrosion resistance.
For saltwater applications, choose components specifically designed for marine use and inspect mounting hardware regularly.
Installation Considerations
Proper installation is essential for safety and performance. The mounting surface must be strong enough to support the bracket and motor.
Depending on the boat, installation may involve:
-
Measuring the mounting position.
-
Checking the motor's weight and horsepower.
-
Positioning the bracket correctly.
-
Using appropriate marine-grade mounting hardware.
-
Sealing mounting holes where required.
-
Checking motor clearance.
-
Testing the steering and tilt range.
If the installation requires modifications to the boat's structural components, professional marine installation may be appropriate.
Maintenance
Regular inspection can help identify problems before they become serious. Check the bracket for cracks, corrosion, loose fasteners, damaged welds, and signs of movement.
Pay particular attention to mounting bolts and hardware. Any component showing significant wear or damage should be inspected and replaced as necessary.
Outboard Motor Brackets in Canada
Canadian boat owners can find outboard motor brackets through marine equipment retailers, fishing stores, boat dealerships, and specialty online suppliers.
When shopping for an outboard motor bracket in Canada, compare the product's weight capacity, horsepower rating, dimensions, mounting requirements, and compatibility with your boat and engine.
Cold weather storage and saltwater exposure can also affect marine hardware, making durable construction and proper maintenance especially important.
Final Thoughts
Outboard motor brackets provide a practical mounting solution for primary and auxiliary outboard engines. From fixed transom brackets to adjustable kicker-motor mounts, different designs are available for fishing boats, recreational vessels, tenders, and other marine applications.
Before purchasing, confirm the motor's weight, horsepower, shaft length, and mounting requirements. Also verify the bracket's capacity and compatibility with your boat. Choosing the correct bracket and installing it properly can provide a secure and dependable foundation for your outboard motor.
