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

Pulling a boat engine is a complex task that requires careful preparation and execution. The process involves several steps, including disconnecting the battery, steering, and control cables, as well as draining the engine's fluids. It is important to have a clear understanding of the engine's components and their functions before attempting to remove it.

One of the critical aspects of pulling a boat engine is having the right equipment. This typically includes a gantry or hoist system to lift the engine, as well as a vehicle to tow the boat. Safety is also a key consideration, with stability and secure fastenings being essential to prevent accidents.

While it is possible to pull a boat engine with the help of a friend, it may be more efficient and safer to seek professional assistance. Marinas often have the necessary equipment and expertise to remove boat engines, ensuring the process is completed correctly and minimising the risk of damage to the boat or engine.

Using a hoist or crane

First, you need to decide on the type of hoist or crane you will use. There are several options available, including engine hoists, gantry cranes, and automotive hoists. Consider the weight of your engine and the height you need to lift it when choosing your equipment.

If you choose to use an engine hoist, make sure it has enough capacity to handle the weight of your engine. You may also need to add an extension to the boom for more height. Always use safety measures such as concrete cinder blocks and sandbags to stabilise the hoist and prevent it from tipping over.

For gantry cranes, you can purchase a pre-made one or build your own. Gantry cranes typically consist of twin parallel top beams with a trolley riding on industrial wheels. Ensure the trolley can move along the beams with ease, even when under load. Gantry cranes provide more control and precision when moving the engine.

When using an automotive hoist, be cautious of weight restrictions and ensure the hoist can handle the engine weight. You may need to distribute the weight by placing a piece of wood over the joists and attaching an eye hook for the hoist. Always use safety measures such as chains or cables to secure the engine.

Before lifting the engine, prepare the area by ensuring the boat is securely blocked or on a trailer. Have all the necessary tools and equipment ready, including slings, chains, and safety gear. Plan the lifting process carefully and ensure you have enough clearance to avoid any obstacles.

When you are ready to lift the engine, attach the hoist or crane to the engine using appropriate lifting points. Slowly lift the engine, being mindful of any obstacles. If using a gantry crane, you may need to coordinate with an assistant to move the trolley and hoist simultaneously for precise engine placement.

Once the engine is lifted, you can make any necessary adjustments or repairs. Always work with a partner when handling heavy engines to ensure safety. When you are finished, carefully lower the engine back into place, ensuring it is securely attached to the boat.

Remember to follow all safety precautions when working with heavy equipment and engines. With proper planning and equipment, you can successfully pull a boat engine using a hoist or crane.

Preparing the boat and engine

Before you start, you'll need to disconnect the battery, steering, and control cables. Coil and stow these neatly, as you'll want to keep them in good condition if you plan to sell the engine or its parts. Gauges, controls, and wiring harnesses should also be removed carefully and stored safely. As you do this, tie a pull-cord to the end of the wiring harnesses and pull it through the chase to make it easier to install a new harness.

Next, you'll need to drain the engine's fluids. For an outboard engine, pull the plug on the lower unit and drain the oil. If it's a four-stroke engine, you'll also need to drain the crankcase oil and remove the oil filter. Additionally, remove any internal fuel filters and drain the fuel lines.

Now, you need to decide how you will lift the engine. If you have a tree in your yard with a branch at least eight inches in circumference and at least two feet higher than the top of your engine, you're in luck! Simply back the boat under the branch. Otherwise, you'll need to construct a freestanding gantry.

To build a gantry, you'll need four legs, a main transverse beam, and cross-bracing. Use six-by-twos for the legs and cross-bracers, and a four-by-four for the transverse beam, as it will bear the most strain. Secure the bases of the gantry by driving stakes at least one foot into the ground and attaching the legs to them. This will ensure the structure is stable and sturdy. Use large C-clamps to secure each piece in place as you drill holes and bolt the sections together.

With your gantry or tree branch ready, hitch your tow vehicle to the trailer and position the boat so that the engine is centred underneath.

Lifting the engine

Lifting a boat engine can be a challenging task, but with the right tools and preparation, it can be done safely and efficiently. Here is a step-by-step guide on how to lift a boat engine:

Preparation:

Before you begin, make sure you have all the necessary tools and equipment, such as an engine hoist, chains, straps, or a block and tackle system. Ensure that you have a clear and level workspace with enough room to manoeuvre the engine. It is also recommended to have an assistant to help with the lifting process and ensure stability.

Step 1:

Disconnect the engine from all cables, hoses, and wiring. This includes fuel lines, coolant hoses, electrical connections, and any other components that may be attached to the engine. Make sure to label or mark each connection to facilitate easier reassembly.

Step 2:

If your boat is on a trailer, you can adjust the trailer to make it easier to access the engine. Lower the trailer tires or use jack stands to get the boat as low as possible. You can also raise the front of the trailer to lower the transom and create more clearance.

Step 3:

Secure the engine hoist or lifting apparatus to a sturdy overhead structure, such as a beam, tree limb, or overhead beam. Make sure the structure can support the weight of the engine. If using a block and tackle system, ensure that it is properly rigged and secured.

Step 4:

Attach the chains or straps to the engine securely. Ensure that the connections are tight and will not slip. Double-check that the weight of the engine is distributed evenly to avoid any imbalance during the lift.

Step 5:

Begin lifting the engine slowly and steadily. Have your assistant guide the engine and monitor for any signs of instability or shifting. If using a block and tackle system, use a winch or pulley to control the lift. Ensure that the engine is clear of any obstacles as you lift it.

Step 6:

Once the engine is lifted to the desired height, secure it in place. You can use additional chains or straps to hold it in position. If necessary, move the boat out from under the engine by pulling the trailer with a truck.

Step 7:

Lower the engine slowly and carefully to the ground or onto an engine stand. Ensure that the engine is stable and secure in its final position. You can now transport the engine or perform any necessary maintenance or repairs.

Remember to always put safety first when lifting a boat engine. Do not attempt to lift an engine without proper equipment or assistance. With careful planning and execution, you can successfully lift and remove a boat engine.

Removing the engine

Before you start, disconnect the battery, steering, and control cables. Coil and stow the cables neatly, as you may want to sell them along with the engine. Next, remove the gauges, controls, and wiring harnesses, being careful not to damage them. Tie a pull-cord to the end of the wiring harnesses and pull it through the chase to make installing a new harness easier. Remove all fluids from the engine, including oil and fuel.

Now, you need to establish a gantry, or a frame used for hoisting heavy objects. If you have a tree in your yard with a branch at least eight inches in circumference and at least two feet higher than the top of your engine, you can use that. Otherwise, you'll need to construct a freestanding gantry. This will need four legs, a main transverse beam, and cross-bracing. Use stakes to secure the bases of the gantry to ensure stability.

Use a webbed strap with sufficient weight capacity to attach a come-along (a device for lifting heavy loads) to the transverse beam. Attach the come-along to the engine's lifting eye, which may be permanently mounted or require screwing in. Ratchet the come-along until there is minimal tension on the strap.

Remove the nuts and bolts securing the engine mount and transom. As there will still be pressure on the bolts, you'll need a partner to help you with the next step. Pull the boat forward slowly while your partner holds the motor and gently rocks the lower unit back and forth to jiggle the bolts free without damaging the mounting holes. Once this is done, you can pull the boat clear and leave the engine hanging.

Seal the transom holes with silicone to prevent moisture from getting in, then list the engine for sale if desired. When the buyer arrives, back their truck under the outdrive and use the come-along to lower the engine, cushioning it with old life jackets.

Selling the old engine

Once you've pulled your boat engine, you might be wondering what to do with it. Here are some options to consider if you're thinking of selling your old engine:

Selling Privately

If you have the time and energy, you could consider selling your old engine privately. This option gives you more control over the selling process, but it can also be more time-consuming and may require some knowledge of pricing and advertising. You will also need to be available to meet with potential buyers and handle the payment process yourself.

Consignment with a Marine Company

If you don't want to deal with the hassle of selling your engine yourself, you can consider consigning it with a marine company like ARG Marine. They will assess the condition of your engine, advise on any necessary repairs, and advertise it to potential buyers. ARG Marine also handles the payment process and ships worldwide. Their service technicians can help you get the best return on your engine, and buyers may feel more comfortable dealing with a shop than private individuals.

Local Marina

Your local marina may also be able to help you sell your old engine. They often have connections with boat owners and may be able to find a buyer for your engine. Additionally, they might have the necessary equipment, such as a forklift, to remove the engine from your boat if needed.

Online Marketplaces

You can also sell your old engine through online marketplaces or classifieds. When creating your listing, be sure to include detailed information about the engine's make, model, condition, and any necessary repairs. Providing clear photos and a detailed description will help potential buyers make an informed decision.

Scrapping or Parting Out

If your engine is no longer in good working condition, you may consider scrapping it for parts. You can sell individual components or the engine block to those who need spare parts for their own engines. This option may not bring in as much money as selling a functioning engine, but it can still be a way to recoup some of your investment.

Remember to keep all the necessary paperwork, such as ownership certificates and bills of sale, to make the selling process smoother and ensure a successful transaction.
