Electric Boat & Kayak Motors

An electric motor is what gets you along a bank quietly, holds a position over a mark and gets a kayak home when the wind turns. Off Grid Superstore stocks 17 Watersnake electric motors and accessories in Australia.

Motors and accessories

Watersnake Electric Boat Motors holds 13 products, including the Venom SXW 54lb 36in 12V transom motor for larger tinnies. Kayak motors cover the lighter end, with the ASP T18 18lb 24in with bracket designed to mount on a kayak or small craft.

Motor Parts & Accessories covers the supporting gear: the GeoSpot GPS sensor for position holding, and the quick-release alloy bracket for lifting the motor off between trips.

Choosing thrust and shaft length

Thrust is rated in pounds and follows boat weight. A rough guide is 2lb of thrust for every 45kg of fully loaded weight, then round up if you fish in wind or current, because a motor working at full output all day flattens a battery fast.

Shaft length matters as much as thrust. Measure from the transom top to the waterline and add around 50cm, so the propeller stays well submerged in chop rather than cavitating every time the bow lifts. A deep-cycle battery is the right power source here; a starting battery will not survive the discharge pattern. See Marine Electrical for batteries and charging.

How much thrust do I need in an electric boat motor?

Work on roughly 2lb of thrust per 45kg of fully loaded boat weight, including people, batteries and gear, then round up if you regularly fish in wind or tidal current. Undersizing means running flat out constantly, which drains the battery far faster than a larger motor at part load.

What shaft length should a trolling motor have?

Measure from the top of the transom or bow mount down to the waterline, then add about 50cm. The propeller needs to stay submerged when the bow lifts in chop, otherwise it cavitates and loses thrust exactly when you need it.

Can I run an electric motor from my starting battery?

It will work briefly, but a starting battery is built for short high-current bursts and is damaged by the deep discharge a trolling motor produces. A deep-cycle battery is the right choice and will last many times longer in this role.

What does GPS spot lock do?

A GPS sensor such as the GeoSpot lets the motor hold a position automatically, correcting for wind and current so the boat stays over a mark without anchoring. It is most useful when fishing structure in moving water.
