SE SPORT 300 Hydrofoil Stabilizing Fin for Outboard Motors - Black, Turbo Trac for Faster Planing

The SE SPORT 300 is a high-performance hydrofoil stabilizing fin that bolts onto an outboard or sterndrive to improve acceleration, reduce cavitation, and deliver smoother, more fuel-efficient planing.

Designed for recreational boaters who want better handling and faster, more efficient rides, the SE SPORT 300 hydrofoil (black) is an aerodynamic fin that installs on the anti-cavitation plate of most outboard and inboard/outboard motors. Built with a profile that encourages rapid glide and a Turbo Trac feature for sharper control, this unit helps boats plane earlier, hold speed at lower throttle settings, and cut through chop with less porpoising and ventilation.

How does the SE SPORT 300 improve my boat's speed and fuel economy?

The hydrofoil reshapes water flow under the transom so your motor reaches planing speed quicker and with less throttle. That reduced resistance lowers fuel consumption for cruising speeds and keeps the hull on plane at slower RPMs when you want steady, economical travel.

• Promotes earlier planing for faster acceleration.
• Reduces drag to save fuel during steady cruising.
• Helps maintain planing at lower speeds for efficient runs.

Will it stop cavitation and porpoising on my boat?

The SE SPORT 300 is engineered to limit cavitation by stabilizing water flow behind the propeller and isolating the prop wash from surface turbulence. It also reduces delfineo (porpoising) by keeping the stern level and smoothing pitch changes over chop.

• Minimizes ventilation and cavitation under acceleration.
• Smooths stern pitch to reduce porpoising.
• Improves consistent thrust delivery for better handling.

How easy is installation and what fits my engine?

Installation is straightforward: the hydrofoil mounts to the anti-cavitation plate of most outboard and inboard/outboard motors using the supplied stainless steel fasteners. No special tools or hull modifications are required — simply align, secure, and test trim and height for optimal performance.

• Fits standard anti-cavitation plates on outboards and I/Os.
• Includes stainless steel screws for corrosion resistance.
• No permanent hull changes; reversible install.

What are the key dimensions and design benefits?

The foil measures 36.5 cm tall by 43.5 cm wide and uses a hydrodynamic shape with an integrated Turbo Trac section to boost control and acceleration. Its profile is tuned to deliver rapid gliding while maintaining directional stability in a variety of water conditions.

• Height: 36.5 cm, Width: 43.5 cm for broad lift distribution.
• Hydrodynamic contour reduces turbulence and drag.
• Turbo Trac feature aids control and quick acceleration.

Who is this for? The SE SPORT 300 is ideal for weekend boaters, waterskiers, and anglers who want tangible improvements in handling, acceleration, and fuel efficiency without permanent alterations to their vessel. It suits owners of outboard and inboard/outboard engines who need a simple bolt-on upgrade to reduce cavitation, improve low-speed planing, and smooth the ride in choppy water.
