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.

Have not received it yet and your already asking for a review?
For anyone curious, installed the L35 on our 190hp MerCruiser Stern drive on our 18.5ft/5.6m 3000lb/1350kg bow rider. Improved time to plane noticeably, especially with full 500kg load (8 people) on board, still planing in under 3 seconds when running a Solas Rubex HR4 prop, 4 blade 14x21 with high rake and high cupping.
Improved cruising on choppy water dramatically by holding the rear of the boat much more stable (not bouncing), like adding shock absorbers (as much as it lifts the rear it also stops it being lifted by outside forces, that's how a hydrofoil works).
No noticeable change in top speed for us keeping at around 47mph, not used long enough to have fuel usage figures, but appears to be using less and has reduced RPMs at set cruising speeds.
Mount and bolts are all 316 stainless steel, brackets are 4.7mm thick and whilst I have not modified them, I did feel the leading edge could have been shaped a little and I still may trim the outside corners on the leading edge, bolts through teh skeg were trimmed down tot he edge of the nuts, foil looks like HPDE Thermoplastic (think white chopping boards but a bit stiffer), about 25mm thick in the middle and well shaped like a wing tapering off in both chord and thickness. Have hit some rocks at low speed, a few small scratches underneath and a couple of nicks in the front edge but no major damage and more importantly no damage to the prop.
Over all very happy with the result and very happy to recommend.
👍👍👍👍👍👍
Installed on Boston Whaler 230 Vantage with 300hp mercury , instant improvement on an already great performing combo , quicker on plane , planes at lower speed and much smoother in chop and crossing boat waves . Must be. More efficient and estimate added 3 knots to top speed 😎👌
Picked up 5km/hr speed and no more tangled ropes on the prop..very happy
