It installs easily in 20 minutes and significantly improves ride smoothness, steering responsiveness, and wave handling in moderate sea conditions, allowing for safer, more comfortable cruising without constant throttle adjustments. ## Description SE Sport 400, 40-unlimited HP - Black SE400GY is Gray SE400BLK is Black Review: Does what it says, well pretty much - Fitted to Yamaha 225hp outboard on Hydrasports 23WA. Reason for purchase was the 23WA is known to need a little stabilizing help at lower planing speeds, not an issue if going fast, but the seas don't always allow that, the workaround to use the trim tabs. Even so the boat would fall off plane and not get back on without more throttle, then would need to be backed off to prevent it going too fast.... enter the hydrafoil .. I had used one years ago to fix a similar issue on another boat. Install was pretty easy, very easy, backed up to a sandbar, 20 minutes with a socket wrench and a screwdriver and the hydrafoil was installed - note the yammy needed to use the outermost holes. First "real" trial was out the never forgiving Merrimack river and to Jefferies ledge 35 miles out in 2-3ft waves. No need to use the trim tabs, motor trim was all, ride was stable at low planing speeds, if speed dropped below 18mph the boat stayed on plane and picked back up to 21-23mph without intervention. Was able to use the trim tabs as designed to fine trim the boat. Return trip at near low tide with cross currents and nasty swells, no problem, dropped to 14mph and stayed on plane, picked back up by itself so all I had to do was steer, nice! Back in calmer waters I was able to reduce the engine trim and the boat remained stable (no pounding) and picked up to 35mph at moderate throttle. Overall - boat more responsive and stable, less pounding, steering more responsive, able to run at lower (more comfortable) speed while on plane. May lose a bit of top end speed due to extra drag from hydrofoil but then the trim tabs are not down and the boat isn't pounding so maybe not.

These are easy to install at the sandbar using the supplied hardware, a 7/16" wrench and Phillips screwdriver. I was able to baseline the boats performance prior to installation, but I have not re-evaluated post installation data yet. These were installed when the boat was at full fuel, and an excess of gear and people aboard. One thing I can say for sure though is that it has gotten the boats tendency to porpoise under control, which was the main reason I wanted to install them. They work. Up on plane at lower RPMs and definitely a smoother ride and less fiddling with the trim control. I've been checking the torque on the nuts and have re-tightened a couple times. I will drill through mount these soon since they are of noticeable benefit. ## Frequently Bought Together - Sport Marine SE Sport SE400 Hydro Foil Gray for 40 HP and Up 74644 - SE Sport 300 Hydrofoil, fits 35 hp - 300 hp engines --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/13001969-hydrofoil-se-400-sport-in-dark-grey](https://www.desertcart.tn/products/13001969-hydrofoil-se-400-sport-in-dark-grey) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-01*
