About this item

  • L35 Compatibility - L35 fits outboards and sterndrives from 100HP-425HP. 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-Shield’s 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.

Shipping thru Amazon was great. First trip with this was very good. Part way through I got caught up on some near a dock. Had awful time getting freed up. Had to limp back to launch site with unknown damage. Product was bent at 45* angle but prop was saved (1st photo ) It did its job well. Have repaired to the best of my ability (2nd photo).Still not like new. Next trip will tell if it worked.Don’t want to spend on a new one if I don’t have to.

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.

I must say that I find myself rating only the best or the worst products everything else is just kind of expected when you’re ordering from Amazon. But this product deserves a positive review!First of all I have never had such superior customer service from any company. Dale (I think he may be the owner and/or maybe the inventor or, at minimum, a A++ vested employee) was literally on the phone with me at 7pm on a random Thursday night answering my questions and texting with me so he could review photos of the placement of my install. In a world that begs not to be bothered with trivial questions about products or any extra help after the initial purchase, Dale was a breath of fresh air. He knew exactly what I was asking, exactly how to help and then he even followed up to make sure I was good with everything! 😲😲🤯So all of that and I haven’t even gotten to how awesome the product is! So I was a little skeptical going in. After all there is a few bad reviews about this thing. I purchased it because I live on a river that has some fluctuations in water level. It’s not bad but it is enough that I have had to replace more than my fare share of props over the last 5 years. I’m not blowing them up daily, but after buying my 4th prop for the boat in 5 years I felt like I should at least look at my options.After having this on my boat for only a week (and probably 16 hours of run time) I can say without a doubt that is working. Obviously the prop is still pristine but that is just the half of it. My boat also has a noticeably faster hole shot, I gained 2-3 mph on my wot without any issues in rpm or cavitation.I can only say good things about this product. If that changes I will repost but for now know that I am thoroughly impressed by this product and the company.And no I was not paid or given this product for this review.Boat info:1998 Rinker Captiva 232 powered by a 7.4l Mercruiser Thunderbolt with a Bravo 1 outdrive running a 14.5 17p 4 blade prop.

This is a brilliant item. I have communicated with the CEO a few times. It was cheaper buying it on Amazon than him donating it to our Veterans With PTSD, Suicide Prevention, 43ft steel hulled sailing Sloop self-funded restoration.Thank you Amazon. Any idea how we could get you to help our very broke but hard working Veterans project?

Fácil instalar ! Mi navegación es en esteros bajos y golpeo mucho y esto me salva de no dañar mi transmisión junto con la propela !! Resta poca propulsión ala salida nada mas

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.

Update: Excellent customer service. Dale responded to my review, although not necessary, and he stands by the product. It seems the product I received had a manufacturing defect, he was able to fulfill the warranty extremely fast. I have seen how well this product performed on my Yamaha 200hp and I recommend it. Not to mention how well it protected my prop in the sand bar. Thank you again for the wonderful product and service.Orig. post. The product did great at protecting the prop but the moment it touches bottom it begins to warp. As you can see in the pictures, it didn’t last very long. I do feel better that the prop wasn’t affected but I’m disappointed that once it touched a sandy bottom it didn’t last very long before it snapped. I followed the instructions during the installation. However, I believe that either the material should be stronger or the aluminum brackets should be longer.
