Electric Float Tube Motor STG-PP2 1800W 42V — Maximum Power for Belly Boat

Electric Float Tube Motor STG-PP2 1800W 42V — The Most Powerful Belly Boat Motor on the Market

The STG-PP2 Motor by 3Lithium Technology is the direct evolution of the acclaimed STG-PP1. It keeps the same weight and compact format, but incorporates a 42V system with 1,800W of real power, delivering radically superior thrust, greater range and instant response even under demanding conditions. Designed specifically for float tube and technical fishing, it's the most powerful float tube motor in its category.

1,800W at 42V — Double the Power at the Same Weight

The STG-PP2's high-voltage architecture delivers forceful torque, superior thrust and immediate acceleration with no equivalent on the float tube motor market. The response feel is comparable to the Evo 42V range for kayaks, but in the ultra-lightweight, compact format designed specifically for belly boats.

The STG-PP2 doubles the power of the PP1 without adding a single gram of weight. For the float tube angler who needs reserve power to overcome current, wind or cover long distances, this is the difference that completely transforms the experience on the water.

Superior Energy Efficiency at 42V

The high-voltage STG controller not only increases power — it also reduces consumption per meter travelled and increases range compared to equivalent lower-voltage systems. At cruising speed, the STG-PP2's efficiency is higher than the PP1's, translating into more kilometers per battery charge. Perfect for long fishing days, extensive movement across large reservoirs and continuous use with no drop in performance.

3Li Water Inside System

The motor cools itself using the very water it operates in, ensuring optimal temperature even at maximum power over long outings. Water Inside technology, combined with anti-corrosion materials and advanced sealing, makes it fully suitable for use in both fresh and salt water.

Telemetry and Advanced Control

The STG-PP2 includes built-in telemetry and is compatible with the STG accessory ecosystem. It provides real-time data on power consumption, battery status and system temperature, enabling smart energy management throughout the fishing day.

Completely Silent Operation

The STG-PP2's highly refined three-phase technology ensures smooth, vibration-free, virtually silent operation. In fly fishing from a float tube, where discretion when approaching the fishing spot is decisive, this feature makes the difference between a productive day and a blank one.

Who Is the STG-PP2 For?

For the float tube angler who accepts no power limitations. Those who cover long distances on reservoirs, those who fish in wind or current conditions the PP1 can't comfortably overcome, and those who want the maximum travel speed available in a float tube motor. It's also the ideal choice for professional fishing guides who need absolutely reliable equipment under any condition.

Recommended Battery

The STG-PP2 is optimized to work with 3Lithium's 42V batteries, especially the 1,300Wh option, which provides the best balance of power, range and weight for this motor. Check our range of compatible batteries at info@3lithium.es.

Frequently Asked Questions

What's the main difference between the STG-PP1 and the STG-PP2?

The STG-PP2 doubles the power of the PP1 (1,800W vs 900W) by running at 42V instead of 24V, while keeping the same weight and compact format. The PP2 offers greater thrust, higher top speed and better performance in adverse conditions. The PP1 is enough for standard use in calm waters; the PP2 is for those who need the maximum performance available.

Can I use the same battery I had with the STG-PP1?

No. The STG-PP2 requires 42V batteries. It is not compatible with the PP1's 24V batteries. You'll need to purchase a specific 42V battery from the 3Lithium range.

Is it compatible with all float tubes?

The STG-PP2 is compatible with the vast majority of float tubes on the market via 3Lithium's specific belly boat mount. For models with special geometry, check with our technical team at info@3lithium.es.

What range can I expect with the 1300Wh battery?

At cruising speed on a standard float tube, estimated range with the 1,300Wh battery exceeds 4-5 hours. At low speed it can exceed 8 hours. Actual values depend on the angler's weight with gear and water conditions.
