PERFORMANCE TEST:
It is imperative to accurately measure the transom mount height for an Epropulsion outboard. Having the wrong measurement for the shaft length can drastically affect the performance of the outboard. If the measurement taken is too short for the transom mount, the propeller will not sit deep enough in the water. When the propeller does not sit deep enough in the water it will cavitate and decrease efficiency. If the measurement taken is too long for the transom mount, the propeller will sit too deep into the water. When a propeller sits too low behind a boat, it will have increased water resistance and reduced speeds.

How to Find Your Shaft Length

If you are looking for an ePropulsion electric outboard for your boat, choosing the correct shaft length is important. 
*NOTE* TAKACAT, Aircat, Bris and other Fully Inflatable Catamarans require the SHORT Shaft – due to shallow transom depth in the water. 
Please note that ePropulsion has a different shaft length measurement from gas-powered outboards. For electric outboards, the shaft length is measured from the top of the clamp bracket to the center of the propeller. For gas outboards, it’s measured from the top of the clamp bracket to the anti-ventilation plate.

As you can see, our XS is close to S from Mercury. Our S is close to L from Mercury. Our L is longer than L from Mercury. See below.

To find the suitable shaft length, the principle is to make sure the top of the propeller is matched to the lowest point of the transom. In order to get the right shaft length, first, measure the transom height, the length from the top of the boat transom to the bottom of the boat.

After that, you could choose the recommended shaft length based according to the transom height.

For most small dinghies and aluminum boats under 15ft, extra short shaft and short will work, depending on the transom height, some over 15.7 inches, some not.

For boats with the transom height higher than 50 cm / 19.7 inches, a long shaft version is more suitable. For daysailers, sports boats and other sailing boats it’s best to measure the distance from the water line to the top of your outboard mount.
