Stand-up paddleboarding is a fantastic way to explore lakes, coastal bays and calm ocean waters. However, strong headwinds, long-distance trips or fatigue can quickly turn a relaxing adventure into a tiring workout. That is where a fin-mount SUP thruster comes in.

Seayoo’s Y-series SUP motors, including Y04, Y02 and Y01-Pro, are designed to clip onto your existing SUP fin box without complicated modifications. They share the same easy-install design but differ greatly in power, battery capacity, speed and suitable scenarios.

Many paddlers get confused when choosing between these three models. This guide breaks down the specs, strengths, drawbacks and ideal users for each Seayoo SUP thruster, so you can confidently pick the one matching your paddling style.

What Is a Fin-Mount SUP Thruster?

A fin-mount SUP thruster replaces your standard SUP fin. It fits directly into the universal fin box on most inflatable and hard stand-up paddleboards. No drilling, no permanent board changes.

You control the motor via a compact wrist remote. You can turn power on/off and adjust speed while standing on your board. It helps you fight against wind and current, extend your cruising range and reduce arm fatigue.

Important reminder: Y04, Y02 and Y01-Pro are surface propulsion units. They are built for surface SUP cruising only. They cannot be used for underwater diving. If you need a unit for both surface cruising and underwater exploration, check out our Flypack underwater thruster.

Frequently Asked Questions

Are Y-series thrusters compatible with my inflatable SUP?

Seayoo Y04, Y02 and Y01-Pro fit most standard SUP fin boxes, including most inflatable and hard paddleboards. Some specialty or vintage boards use non-standard fin mounts. Double-check your fin box size before purchase.

All three models support saltwater use. After every saltwater session, rinse the thruster with fresh water to remove salt residue, to avoid corrosion and extend service life.
