QUICKMARINER Hydrofoil Stabilizer for Outboard and Sterndrive, Yellow, 5–150 HP, UV-Stable Nylon Lift Wing

QUICKMARINER Hydrofoil Stabilizer is a bolt-on Doel-fin style wing that mounts to outboard and sterndrive lower units (5–150 HP) to reduce bow rise, minimize ventilation and smooth the boat's ride.

Designed for small to mid-sized powerboats, this hydrofoil stabilizer attaches to most Yamaha, Mercury, Honda, Suzuki and Tohatsu outboards and stern drives up to 150 horsepower. Constructed from UV-stable, reinforced PA66 nylon, the fin adds lift and trims the lower unit to improve handling in choppy water while being simple enough for DIY installation. The package includes the stabilizer, stainless hardware, a 6.5mm drill bit and installation instructions so you can fit it yourself.

How does this hydrofoil alter my boat's handling?

The stabilizer creates a small hydrodynamic wing under the lower unit that generates lift at speed, helping to control bow rise and stabilize pitch. That lift also repositions thrust to keep the propeller fully engaged, reducing ventilation and improving acceleration consistency.

• Produces lift to reduce nose-up attitude at planing speeds
• Helps keep propellers submerged to lower cavitation risk
• Stabilizes pitch in chop for a steadier ride

Will it fit my engine and how difficult is installation?

The fin is made to be compatible with many common outboards and sterndrives up to 150 HP; its universal Doel-fin profile supports custom drilling and minor trimming for a tailored fit. Installation is straightforward for anyone comfortable with basic tools—mounting hardware and a drill bit are supplied.

• Fits Yamaha, Mercury, Honda, Suzuki, Tohatsu lower units (up to 150 HP)
• Includes stainless screws, nuts and a 6.5mm drill bit for mounting
• Requires simple hand tools; instructions are included for DIY fitment

What performance benefits can I expect on fuel and rough water?

By improving trim and reducing ventilation, the hydrofoil can improve propulsion efficiency and make the hull run more smoothly across waves. While exact improvements depend on boat type and conditions, many operators notice steadier speeds at lower throttle settings and a more comfortable ride in chop.

• May lower fuel usage by enabling efficient cruising trim
• Reduces throttle corrections from ventilation or porpoising
• Improves comfort and control when encountering wakes or rough patches

Who this product is for: boat owners and DIY mechanics who use outboards or sterndrives from small tiller motors up to 150 HP and want an affordable, non-invasive add-on to enhance trim, reduce prop ventilation and produce a smoother ride. It’s aimed at recreational anglers, runabout owners and weekend boaters who prefer a simple installation and corrosion-resistant materials. If you regularly encounter chop, frequent planing speeds or want to experiment with aftermarket trim solutions, this QUICKMARINER stabilizer is a practical upgrade option.
