Watersnake T18 ASP 18lb Thrust 12V Electric Trolling Motor

Fitting a motor built for a dinghy or small powerboat onto a belly boat adds weight and bulk that fights against everything a belly boat is meant to be — light and simple. Watersnake's T18 ASP takes the opposite approach, built specifically for small, light watercraft.

At just 2.2kg it is one of the lightest trolling motors on the market, with 18lb of thrust — plenty for gentle repositioning or trolling on a belly boat without overpowering a light hull. The 24-inch shaft and adjustable transom mount, along with an anti-impact clip system, are built for fast, secure attachment rather than a permanent installation.

It suits anyone who wants occasional motor assistance — covering distance, trolling a lure, or resting tired legs partway through a session — without committing to the weight and complexity of a motor built for a bigger boat.

Frequently Asked Questions

Is this motor too small to be useful?

18lb thrust is modest by trolling motor standards, but it is matched deliberately to light craft like belly boats, kayaks and small inflatables, where a bigger, heavier motor would be overkill and add unnecessary weight.

How is it attached?

It uses an adjustable transom mount with an anti-impact clip system, designed for fast, secure attachment rather than a permanent fixed installation — suited to a boat you set up fresh each trip.

Which of your belly boats can take this motor?

Our pro-motor compatible models (Savage Gear High Rider, Savage Gear Pro Motor, and the Black Cat Battle Boat Set, which ships with its own motor) are built for motor fitment. Check compatibility before fitting a motor to a standard float tube.

What does delivery cost and how long does it take?

Delivery cost and an estimate for your address are shown at checkout before you pay. Free delivery applies over the qualifying order value.

Can I return it if it is not right?

Yes — return it unused, with packaging where possible, under our returns policy for an exchange or refund.

Is checkout secure?

Do you actually need a motor on a belly boat?

3 min read Float & Cast

A motor isn't essential for belly boat fishing, but for the right angler it changes what a session looks like — as long as the motor is sized correctly for the boat.

When a motor genuinely helps

Covering real distance, trolling a lure over a productive drift, or simply resting tired legs partway through a long session are the situations where even a modest motor like this earns its place. For short, static sessions close to launch, it's less necessary.

Why weight matters more here than on a normal boat

A belly boat's whole appeal is being light and simple to transport. A heavy trolling motor undoes that trade-off. At 2.2kg, this motor adds meaningfully less bulk than motors built for bigger boats, keeping the belly boat's core advantage intact.

Checking compatibility before you buy

Not every belly boat is built to take a motor mount safely — check our pro-motor compatible range (Savage Gear High Rider, Savage Gear Pro Motor, and the Black Cat Battle Boat Set) rather than assuming any float tube can take one.

Getting sensible run time

18lb thrust motors are efficient but still battery-dependent — plan your session length against your battery's realistic run time, and always carry a paddle as backup in case the motor or battery lets you down mid-session.
