Hydro Shield will get your boat on plane faster, allowing you to remain on plane at lower speeds and rpm's. It also improves handling and lowers your fuel burn at low and cruising RPM settings. Hydro-Shield will also protect your propeller from damage due to underwater impacts, and its 316th's marine grade stainless steel bracket system acts as a skeg guard, strengthening and reinforcing the skeg.

Made from an energy-absorbing plastic compound, Hydro Shield can withstand impacts, natural or man-made. Even if your boat strikes natural hazards like rocks, coral, oyster beds, or sandbars, or man-made hazards like lobster and crab pots, Hydro Shield maintains its integrity and protects your prop and skeg.

Hydro Shield is even easy to instal as the installation generally takes around 25 minutes for someone who has not installed one before, If you have any questions, please call or text us at (302) 650-4326.

Easy

Easy to install, seems to work great. Have been out a couple to times with different loads on the boat and I'm very pleased with the handling.

every boat of mine has one

I have two work boats and three fun boats and every single one has a Hyro Shield on it. We rescue Manatees and these give us piece of mind and the performance aspect is unreal. Those other cavitation plate "wings" or "fins" simply add drag and offer very little performance increases. THESE, however, exceed every expectation and truly deliver. From prop strike protection, planing speed, wild life protection, crabpot protection, these deliver! I'm a customer for life, Their customer service is first rate as well. They answer emails and phone calls promptly and professionally. TRUST this product! I do with every single one of my boats.

Ready to test out the Hydro-Shield

I just installed the Hydro-Shield on my Volvo Penta outdrive and looking forward to seeing how well it works. I recommend this to a friend and he put it on right away and put it in the water. We noticed a significant difference on getting his boat to plane much faster and without a lot of throttle as he had to in the past. And the turning radius was much better. I will update my post as soon as I get my boat in the water.

Can’t wait to try it 😁

I have just fitted the larger hydro shield to my Fourwinns horizon 200 with a duo prop leg and looking forward to seeing the improvements . I will report back once I’ve tested it.
The only improvement I would say you can make is please have a very good instructional video made as it is very simple to fit once you’ve done one they’re a doddle! I did find it quite nerve racking drilling holes in my Skeg
