Can a short shaft outboard be converted to a long shaft?

When it comes to boating, having the appropriate outboard motor height is crucial. If the motor is too low, it can cause the boat to take on water or create more drag, while if it is too high, it can affect the handling and stability of the vessel. This is why it is important to have the correct shaft length for your outboard motor. But what happens if you have the wrong shaft length??

The answer is yes, it is possible to convert a short shaft outboard to a long shaft, but it is not a simple process. In general, the conversion requires a new outboard motor leg or midsection, which is the section of the motor that connects to the boat. The new leg will have a longer shaft, which will bring the propeller to the appropriate depth in the water.

The first step in this conversion process is to determine what length of shaft is needed for your boat. This can be done by measuring from the mounting bracket to the cavitation plate, which is the metal plate above the propeller. This distance will determine the correct shaft length needed.

Once you know the correct shaft length, you will need to find a compatible midsection or leg for your outboard motor. This can be a challenge, as not all models are compatible with each other. It is important to do your research and consult with a professional to ensure that the correct parts are used.

Once you have the new leg, you will need to remove the old leg from the motor and replace it with the new one. This can be a complex process, as there are many components that need to be disconnected and reconnected correctly. It is important to follow the manufacturer’s instructions carefully and to have the necessary tools and knowledge to complete the conversion.

Overall, converting a short shaft outboard to a long shaft is possible, but it is not a simple process. It requires finding the correct parts, having the proper tools, and following the manufacturer’s instructions carefully. If you are unsure about the process or lack the skills needed, it is best to consult a professional who can assist you in converting your outboard motor to the appropriate shaft length for your boat.
