If your boat is on a trailer, one method is to use the front loader to lift one end of the pallet or engine, allowing the other end to rest on the truck or trailer. You can then drive the tractor forward to slowly ease the load down to the ground. Ensure that you use proper attachments, such as heavy-duty chains or straps, to secure the load to the loader. Avoid lifting from the bucket of the loader, as this can put stress on the hydraulic lines. Instead, consider using pallet forks or other specialized attachments designed for lifting heavy objects.

Block and Tackle

A block and tackle system utilizes a set of pulleys and a rope or cable to lift heavy loads. This method has been used for centuries and is commonly employed on boats and sailing ships. By increasing the number of pulleys, you can gain a greater mechanical advantage, making it easier to lift heavier loads.

To use a block and tackle, start by hanging the top pulley at a comfortable height. Thread the rope through the pulleys, following the manufacturer's instructions, to create the desired mechanical advantage. Secure one end of the rope to a fixed point, such as an overhead beam or tree, and attach the other end to the engine. By pulling on the rope, you can lift the engine, move the boat out of the way, and then lower the engine to the ground or onto a pickup truck.

When using a block and tackle, it is important to consider the friction and tension in the system. Ensure that the rope is threaded correctly and that there is sufficient lubrication on the pulleys to reduce friction. Additionally, always inspect the system for any signs of wear or damage before use to ensure safe operation.

Whether you choose to use a front loader or a block and tackle, it is crucial to prioritize safety. Ensure that you have a clear plan, stable equipment, and secure attachments before beginning the lift. With careful preparation and the right tools, you can successfully lift an inboard engine from your boat.
