It is compatible with all Evinrude, Honda, Johnson, MerCruiser, Mercury, Suzuki, Tohatsu, and Yamaha sterndrives on boats over 18 feet. Four different sizes available. Check chart for compatibility. Note: Select the R-size hydrofoil for pontoons up to 26 feet and 115HP.
- Improve Performance - The skeg-mounted L-35 hydrofoil for outboard engines and inboard/outboard sterndrives gets your boat on plane faster, enables it to remain on plane at lower speeds and RPM settings which translates to improved fuel economy at the low & mid RPM settings. Improved handling and enhanced helm control are additional benefits aside from protection for the prop, skeg and lower unit gearing.
- Shield Your Propeller - Our high quality, energy-absorbing thermoplastic compound is designed to reduce damage and costly repairs due to underwater impacts at low and moderate speeds. The included bracket system provides added skeg protection.
- Protect Marine Life - Prevent wildlife death or injury due to propeller strikes. Hydro-Shields attachment to the bottom of your motor leaves manatees, sea turtles, and aquatic grass beds unscathed in the case of contact.
- Easy Installation - This simple, two-step process can be completed in 20 25 minutes. The kit is Made in the USA and includes all of the hardware you need, including marine-grade Stainless Steel bracket system with bolts and lock nuts.

Excellent product. I've purchased three of these now, one for my Yamaha 225 and this is the second one for my Merc 350. Both improved the handling of the boat. The ONLY reason I'm buying the second one it the first one did it's job. Boating in Keys and hit a big rock. It saved the prop but did bend the mounting so new one on route. If you boat in thin water a lot, it's well worth the investment. MUCH cheaper than a propeller of a foot assembly!

Easy to install and work like it claims it does. If you boat on a river it is a must have.

The media could not be loaded. I literally cannot believe the change this made in the performance and speed I’m seeing out of my engine! - I had already been impressed with the incredibly durable, quality feel of the shield itself, (not to mention how much better it looks after completely hiding my ugly, scraped up skeg!) but after seeing and experiencing the proof first hand, I’m hands down a believer that this one is going to revolutionize the outboard game! - Install was as simple as you expect! My skeg had a curve to its shape, so I used my clamps to squeeze the middle of the brackets with a wrench between the top of them to “fan” them out just a touch - Measure and Measure again!! - Ensure the front and the back are equal distance from the cavitation plate! And if you need to, use a couple clamps to hold things still! - They instruct you to drill your top rear hole first which is a HUGE help to keep your self on track as you measure one more time before committing to the position! (Totally grateful for that foresight in the design process!) - I hit 18mph with an 8hp four-stroke (to be fair it has a ”9.9” carb) but the fastest I’ve EVER been on that dinghy was MAYBE 10mph for about half a second - (Don’t get me wrong, I love my dinghy, but the planing speed has always been horrible!) - Aside from the speed increase, the smoothness and stability of my turns can’t be given any justice from the video, as it just feels so much better to me than before with the slip being all but gone - I couldn’t begin to praise this one enough! - 15/10 take my money again and again!!

This was an easy enough install and helped my deckboat with an alpha one throw a better wake for surfing, however, I bumped it into the shore once and now the mounting brackets are bent so that its leaning to the right and it caused the tip of the skeg to snap off where the hole was drilled. The plastic is also very rough now as if someone has taken sand paper to it. It has also robbed about 5mph of top speed from the boat. I need to get new brackets since mine are bent and I dont know what to do about the rough texture of the plastic. Ill probably end up going with a traditional whale tale and stainless skeg protector from here.

I usually never write reviews but this made the list for doing so. I purchased a Hydro Shield last spring on my Monterey 214fs with a 5.0MPI and Alpha 1 outdrive because I was looking for a solution to porpoising. Well the Hydro Shield fixed that problem and also added some performance from getting up on plane sooner and also cruising at a lower rpm. Now the fun part. I recently had the boat in Florida and being a northerner on Lake Erie i quickly found the moving sand bars to be tricky to navigate and ran into quite a few dragging the outdrive. Hit some harder than others but thankfully because of the Hydro Shield I never tore up the prop or damaged the skeag. Here is where the Hydro Shield saved my but. All loaded up and trailering home on I-75 somehow my outdrive decided to spring a hydraulic leak and lower the outdrive. A nice passer by in the fast lane let me know, thankfully. Pulled off the highway fearing the worst and low and behold the Hydro Shield was scraping the pavement, completely melted but saved the outdrive. I will never be without one on my boat. Jason

I have a 2024 tidewater 2110 Baymax with a Yamaha 150 and had a heck of a time maneuvering it at low rpm. Docking and trailering was a real pain. I have the newer hydraulic steering and hated it! Not as responsive as a cable and you have to spin it like a top to get a reaction. My boat has a flatter bottom since it’s a bay boat (10 inch draft) so it’s just slow to react. I saw this advertised as quicker on plain and better handling so I gave it a shot and I can’t believe how it changed my boat. It steers better, comes on plane better and I can’t believe the difference. Kinda went from riding on ice with slicks to snow tires with chains. The boat rides a bit higher than before at any RPM giving a smoother ride. Great product.
