When selecting a Mercury outboard motor for your boat at Mercury Outboard Depot, ensuring you have the correct shaft length is critical for optimal performance and safety. Here’s a simple guide to help you make the right choice.
Step 1: Locate the Measurement Points
Top of the Boat Transom: This is the upper end of the back section of your boat where the motor is mounted.
Bottom of the Boat (Lowest Point): The lowest part of your boat's hull at the back.
Step 2: Measure the Height
Using a tape measure, determine the vertical distance from the top of the boat transom to the bottom of the boat. This is the area where the engine will hang.
Step 3: Select Your Shaft
Based on the distance you measure, choose from the following shaft lengths for your Mercury outboard motor:
14" – 17 1/2": You need a "Short" shaft (15").
18" – 22": A "Long" shaft (20") is suitable.
22 1/2" – 27": Go for an "Extra/Ultra Long" shaft (25").
Correct shaft selection ensures that the motor's cavitation plate is at the right height, minimizing drag and avoiding potential damage from underwater hazards. It also optimizes the boat's overall performance.
