How to install a long shank outboard motor on a short shank boat?

Installing an outboard motor on a boat can be a bit tricky, especially when dealing with a long shank motor on a short shank boat. However, with the right tools and techniques, anyone can accomplish this task with ease.

So, here is a step-by-step guide on:

Step 1: Measure the shaft length

The first step is to measure the shaft length of the existing motor. This will help you to identify the type of motor you need to install. A short shank outboard motor typically measures 15 inches, while a long shank model can measure between 20-25 inches.

Step 2: Choose the right motor

Once you know the length of the existing motor, you can choose the right long shank motor that will fit properly on your boat. It’s important to select a motor that matches the horsepower rating of your boat.

Step 3: Remove the old motor

The next step is to remove the old motor from the boat. Start by removing any bolts, nuts, and screws that hold it in place. Be sure to disconnect any wiring or fuel lines, as well.

Step 4: Check the transom

After removing the old motor, check the transom on the boat. Ensure that it’s sturdy enough to support the weight of the new motor. If necessary, add reinforcement to the transom to provide additional support.

Step 5: Install the bracket and motor

Once you have the transom sorted, install the bracket that holds the motor to the boat. Use the mounting bolts and screws that come with the motor to attach it to the bracket. Be sure to place the motor in the correct position, keeping it level and centered.

Step 6: Connect electrical and fuel lines

With the motor in place, connect the electrical and fuel lines to the appropriate connections. Ensure proper fittings and tight connections, so that they don’t come loose while out on the water.

Step 7: Adjust the motor height

The final step is to adjust the height of the motor. This is important to ensure that the propeller operates properly in the water. Move the motor up or down until it sits at the correct height, then tighten the clamps to hold it in place.

Installing a long shank outboard motor on a short shank boat can seem daunting at first, but it becomes a straightforward process by following these steps. By taking your time and utilizing proper techniques, you’ll have a reliable motor that will provide years of quality use on the water.
