Hoisting A Boat Engine: A Step-By-Step Guide

Hoisting a boat engine is a complex task that requires careful planning and execution. It involves the process of lifting, lowering, or transporting an outboard motor on a boat. This task can be accomplished using various methods and equipment, such as engine hoists, cranes, or even creative solutions like using a tree branch or a wooden gantry. Safety is a primary concern, and it is crucial to have a sturdy setup and a clear understanding of the process before attempting to hoist a boat engine.

How to Hoist a Boat Engine

Using a cherry picker engine hoist

Step 1: Prepare the Work Area

Before you begin, ensure you have a clear and level surface to work on. Park your boat and trailer in a spacious area, and make sure the engine hoist is stable and secure.

Step 2: Measure Clearance Height

Determine the height you need to clear. Measure the distance from the floor to the top deck of the boat, and ensure your cherry picker can extend high enough. Most cherry pickers have a maximum height of around 8 feet, but some can go up to 100 inches or more.

Step 3: Secure the Engine

Now, it's time to secure the engine to the cherry picker. This step is crucial for safety, so take your time and use the proper equipment. Start by attaching a lifting eye to the engine. The lifting eye screws into the flywheel, replacing the flywheel nut. This provides a secure point to lift the engine.

If your engine doesn't have a lifting eye, you can use high-strength rope or large tie-down straps. Wrap the rope or straps around the powerhead, ensuring they are securely tied and won't slip. You can also create a makeshift lifting eye by drilling a small piece of angle and attaching it to the engine with bolts.

Step 4: Hoist the Engine

Once the engine is securely attached, you can begin to hoist it. Slowly raise the cherry picker, keeping a close eye on the engine's stability. Be cautious, as the engine may swing or shift as the centre of gravity changes.

Step 5: Lower and Secure

When you've reached the desired height, carefully lower the engine. Guide it to the engine stand or desired location, ensuring it doesn't tilt or swing unexpectedly. Once the engine is in place, secure it to prevent accidental movement.

Step 6: Final Checks

After lowering the engine, double-check all connections and ensure the engine is stable. Make sure the cherry picker is locked in place and cannot accidentally release or lower the engine.

By following these steps, you can safely and effectively use a cherry picker engine hoist to remove or install a boat engine. Remember always to work with a partner whenever possible, and always prioritise safety when working with heavy equipment.

Building a hoist from scratch

Planning and Design

Start by determining the weight of the boat engine you need to hoist. This will help you choose the right materials and design a safe and stable hoist. Consider the weight capacity of the hoist and select materials that can handle the load. Ensure that you have a clear understanding of the hoist's purpose and the specific requirements, such as the height and width needed to straddle the stern of the boat.

Materials and Tools

For the frame, you will need sturdy materials such as wooden beams (2x4s and 2x6s) or square tubing made of metal. The type of material you choose will depend on your budget, the weight of the engine, and your personal preference. You will also need casters or wheels to make the hoist mobile and adjustable. A winch, come-along, or chain fall will be needed to provide the lifting mechanism. For safety, it is recommended to use a winch or chain hoist that is specifically designed for overhead lifting. Additionally, you will need bolts, screws, and diagonal braces to secure the structure and ensure its stability.

Construction

When constructing the hoist, start by assembling the frame. Ensure that the base is stable and wide enough to provide a solid foundation. The uprights should be securely attached to the base, and the crossbeams should be sandwiched between the uprights for added strength. Diagonal bracing is crucial to prevent lateral movement and ensure the structure's rigidity. Secure all joints and connections with bolts or screws to handle the weight safely.

Safety Precautions

When building and using your hoist, always put safety first. Ensure that the hoist is securely braced and anchored to the ground or a sturdy structure. Test the hoist's stability before attempting to lift any weight. Always use gloves and eye protection when working with the hoist to prevent injuries. Never exceed the weight capacity of the hoist, and be cautious when working at heights.

Additional Tips

You can add a pulley system to increase the lifting force and make it easier to operate. Using a hydraulic ram can also simplify the lifting process by allowing you to raise and lower the engine smoothly. If you need to increase the height of the hoist, consider placing it on a platform or using cinder blocks under the base. Always have a helper when operating the hoist to ensure safety and ease of operation.

Using a forklift

Step 1: Prepare the Boat and Engine

Before you begin, ensure that the boat is securely positioned on a trailer or a stable surface. Disconnect all necessary components and wiring from the engine, following appropriate safety procedures.

Step 2: Position the Forklift

Place the forklift in a stable and level area near the boat. Ensure that the forklift is on level ground and has sufficient clearance to manoeuvre. Adjust the forklift's height and angle to align with the boat engine.

Step 3: Secure the Engine

Use appropriate lifting equipment, such as chains or straps, to securely attach the engine to the forklift's forks. Ensure that the engine is balanced and securely fastened before attempting to lift it.

Step 4: Lift and Hoist the Engine

Slowly and carefully lift the engine using the forklift. Keep a close eye on the stability of the boat and forklift during this process. Once the engine is clear of the boat, you can then move the forklift backward to pull the engine out completely.

Step 5: Lower and Place the Engine

After the engine is clear of the boat, carefully lower it to the ground or a designated work area. Ensure that the engine is securely placed and supported before releasing it from the forklift.

Additional Considerations:

• Ensure that you have a clear and safe work area, free from obstacles and bystanders.
• Always follow safety protocols when working with heavy equipment and machinery.
• Consider the weight and dimensions of your boat engine to ensure that the forklift can handle the load.
• If possible, have an assistant help guide and spot during the lifting process.
• Be cautious when working near water, as the ground may be unstable or slippery.

Using a crane

Step 1: Choose the Right Crane

First, you need to select an appropriate crane for the job. There are several types of cranes that can be used for hoisting a boat engine, such as a gantry crane, engine hoist, or a shop crane. Consider the weight of your engine and choose a crane with a suitable capacity. For example, the 1-ton capacity telescoping gantry crane from Harbor Freight is a popular option.

Step 2: Set Up the Crane

The setup will depend on the type of crane you choose. For a gantry crane, you'll need to assemble it following the manufacturer's instructions. Make sure it is stable and secure before proceeding. If you're using an engine hoist or shop crane, you may need to set up a support structure, such as an A-frame or wooden gantry. Ensure that your crane can safely reach the engine and has enough clearance to lift it out.

Step 3: Secure the Engine

Use appropriate slings, straps, or chains to securely attach the engine to the crane. Distribute the weight evenly and ensure that all connections are secure before lifting. It is crucial to take the necessary safety precautions to avoid damage to the boat and injuries to yourself or others.

Step 4: Lift and Hoist the Engine

Once the engine is securely attached, you can start the lifting process. Operate the crane carefully, ensuring that the engine is stable and doesn't swing or sway. Lift the engine clear of the boat and slowly move it to the desired location. If needed, you can use a trolley or pulley system to traverse the engine along the crane's beam for precise positioning.

Step 5: Lower and Secure the Engine

When you've reached the desired location, carefully lower the engine to the ground or a suitable surface. Ensure that the engine is secure and won't tip over. If you're placing the engine onto a stand or mount, adjust the positioning as needed and secure it in place.
