Fitted hydro shield to my seamaster fitted with a 115 mercury
Engine the boat planes so much faster and handles incredible
Purchased the Hydro Shield for my 16ft Larson with a 75hp Evinrude and despite being a bit skeptical of what I was buying after my first outing with it installed I honestly couldn’t be happier with it. The boat already had come up on plane quite quickly and it improved drastically and I also increased my top end speed by 7 kph when the trim was dialled in.

Still trying it out . When on plane I was limited to about 1/2 what the trim should allow before the boat started porpoising . Now when on plane I can trim past the trailer trim . You can feel the boat coming out of the water for an extremely smooth ride . Very impressed with the improvement.
I bought this out of desperation for a cure to hitting rock bottom on Lake Buchanan, TX. But the extra lift in acceleration was beyond my expectations! This added feature to my boat exceeded all expectations and reviews from other boaters 🤗
bought this fin hopping it would help keep the nose of my bout down when I am trying to toe the kids around the lough tubing so far so good it s been much easier to get them going so for me has been a good purchase and it's doing the job. thanks
This works perfectly on my aluminum utility boat with a 20 hp motor. It now planes properly and gets up on plane much faster.
Five stars! Bravo!
Just had the opportunity to take the boat out after installing the hydro-shield! I was very pleased with the performance ! Boat did come on plane quicker and was more stable at cruising speed with hardly any porpoising, where before I was constantly working the trim. Super simple install. Very satisfied with my purchase.
Installed on a Targa v18. Impressed with the drop in time it took to get on plane. No decrease in top end performance. Highly recommend the product.
This is the second one I've installed. First on a 200 Optimax and now, on a 250 XS Pro! We fish a lot in Crystal River, FL. Purchased due to Manatees, but saved my prop twice on oyster bars.
I have a 16' boat with a 50hp tiller controlled motor that had a bad problem porpoising even in the calmest waters. Hydro-shield not only took that completely away but also made the steering easier and more responsive.
Installed it! But haven’t ran it yet…stay tuned will be tested before summer
It went on fairly easily and has helped our performance and handling
Crazy difference jumps up on plane really fast now differently not a gimmick
