How to Choose the Right Shaft Length?

If you are looking for an ePropulsion electric outboard for your boat, choosing the correct shaft length is important. If you go too long it would still work but it may lack performance. You will also risk hitting bottom or submerged objects more frequently such as rocks. If you go too short, that’s the worst scenario as you‘re more than likely going to cavitate.

Please note that ePropulsion has a different shaft length measurement from petrol-powered outboards. For electric outboards the shaft length is measured from the top of the clamp bracket to the center of the propeller. For petrol outboards it's measured from the top of the clamp bracket to the anti-ventilation plate.

ePropulsion Shaft Length Selection

ePropulsion's XS is close to S from Mercury.

ePropulsion Shaft Length Selection

ePropulsion's S is close to L from Mercury. ePropulsion's L is longer than L from Mercury.

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. Hard to put it into practice? Well, 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. Refer to the table above.

For most small dinghies and aluminium boats under 15ft or 4.5m, extra short shaft and short will work, depending on the transom height, some over 40 cm / 15.7 inches, some not.

ePropulsion Shaft Length Selection

For boats with the transom height higher than 50 cm / 19.7 inches, a long shaft version is more suitable.

ePropulsion Shaft Length Selection

For daysailers and short one-design racing sailboats, it depends on the position of the outboard mount. If you choose Spirit 1.0, we suggest you keep the outboard mount at a lower position so XS will work. That’s because XS takes less space to store inside the cabin.

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.

What's the key differences between Spirit Plus (this product) and Spirit Evo?

The Spirit 1.0 Evo upgrade includes ability for remote controller and steering, or upgraded tiller control with real-time digital display. The Evo model also includes industry first hydro-generation capability, where battery is charged while boat is operating under alternate power.

Can I power the Spirit 1.0 Plus series with an external battery?

Yes, and an external battery power cable is required. We recommend the ePropulsion 48V E-Series Battery to extend the range. We also recommend a cowling for looking good when you remove the original Spirit battery.

How to store the Spirit battery long term?

Store the battery in the dry environment and keep the battery charge level at 60% around, and charge the battery every 3 months.

Is Spirit 1.0 Plus series good for saltwater use?

Yes, it is designed for extensive use in the saltwater. We choose high-quality aluminium alloy as the base material, and apply anodizing coating and powder coating on top of it. For more information see the article How did ePropulsion make an outboard corrosion-resistant?

Will the motor turn off automatically if I forget to power off after use?

Yes, Spirit 1.0 Plus will switch off after 30 mins without operation.
