Troubleshooting & FAQ

How do I confirm this fits my engine? This hydrofoil is designed for a broad range of outboard motors from 8 to 40 HP, including major brands like Yamaha, Mercury, and Johnson/Evinrude. Please check the detailed compatibility table on this page. Note that it specifically does not fit Mercury 4-Stroke 40, 50, and 60 HP models, though it may fit other engines above 40 HP.

Does installation require drilling? Yes, installation requires drilling four holes into the anti-ventilation plate of your outboard motor. To simplify this process, the kit includes all necessary stainless steel mounting hardware and a 6.5mm drill bit.

What is the main benefit of installing a hydrofoil stabilizer? A hydrofoil, also known as a "whale tail," is designed to improve your boat's performance.

I had some jewelry I wanted to gift to mt niece and needed something to send it in. This was a lovely little box, great for travel or sending jewelry in. It was well made, had ample space for different pieces of jewelry and made a really nice little presentation box, imo. It's something she can use regularly on for a trip. I liked it
