Unbelievably Accessory

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 🤗

new fin on boat

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

Fantastic!

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.

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.

2nd!

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.

porpoising problems

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.
