Suzuki Small Outboard Motor Shaft Length Guide

One of the most important factors to consider when purchasing an outboard motor is the shaft length.

  • An outboard motor with the incorrect shaft length can cause performance and handling issues. That is why it is critical to accurately measure the outboard shaft length.
  • This guide will walk you through the steps of measuring outboard shaft length correctly so that you have the right size motor for your boat.

 

Step 1: Gather the Required Tools

  • You'll need a few tools before you start measuring. A tape measure, a straightedge, and a level are required. Make sure your tape measure is at least 25 feet long so you can accurately measure the shaft length.


Step 2: Calculate the Proper Shaft Length

  • The top of the outboard motor should be level with the bottom of the boat as a general rule. This ensures that the motor is at the proper height for maximum performance.
  • A short shaft outboard motor is required if the distance between the top of the transom and the bottom of your keel is less than 15 inches. A long shaft outboard motor is required if the distance is between 16 and 20 inches. If the distance is between 21 and 25 inches, you will need an outboard motor with an extra-long shaft.


Step 3: Examine the Manufacturer's Suggestions

  • Check the manufacturer's recommendations for the appropriate outboard shaft length for your specific boat model. Because the manufacturer's recommendations may differ from the general rule of thumb, it's critical to follow their instructions for the best results.


Step 4: Final Inspections

  • Before buying an outboard motor, double-check the measurements and make sure you have the correct shaft length. It's also a good idea to have a professional double-check your measurements to make sure they're correct.
