Large fin on 18' 9" bay boat with 90 hp Johnson - worked great 1 time out

I haven't had a chance to install yet waiting on my mechanic too get my boat in for electrical work and install my hydro- shield will give a better review next spring.

I installed the hydro-shield on my 50hp Mercury. Installation was easy following the directions. I was able to try it out on the Wisconsin river during a fishing trip.
the Hydro-Shield helped protect the prop and skegg on sand bars and rocks also a lot of floating debris when they opened the dam. It also help get on plane a little faster.

I'm not one to jump on the latest trends, or even write a review unless it's deserved.
Hydro-shield does what it says it'll do.
Quicker to plane.
Lower RPM to stay on plane.
And protect the prop.
I boat in Cedar key florida which is very shallow with sand & oyster bars. Very easy to run into shoaling.
Can't say much on fuel burn as I don't really monitor it, but I'm going to assume it has improved my fuel economy just because of the 1st 2 pro's I mentioned.
Solid product for a reasonable price.

Wotks as described

Made the performance of our Highfield RIB with 60 hp Tahatsu much better. Planes quicker and stays on plane at lower speed. Was able to install in water very easily.

Easy Installation excellent quality works great

The product is great, does what it says. It did take 4 mph off my top end tho. Was a little confusing st first about install, but after watching a few how to videos, I installed in like 15 min. It's definitely worth the money. Just wish it didn't take from my top end speed.

Installation was fairly easy, it took me about 45 minutes, I noticed instantly how quickly my boat jumps up on plane, and she rides smooth well into the turns, glad I bought this product

This is the second Hydro-Shield I have purchased for my last two new Robalo boats. It is worth every penny!! Performance and handling improved once i added it to my 21' boat with a 200HP Yamaha.

Easy to install, have had no issues with the hydro-shield. As advertised it has increased steering response at low speed, fuel economy, and gained 2 mph in speed. Love the prop protection it provides as well. Great product!

Up on plane quickly, easy to install.

It works really well just like the advertisement claims. Planes faster, steers better, & rides smoother on my 5.0 sterndrive

Love it. My Tracker gets on plane in about 30 seconds. Boat control very smooth.

Love this thing. Wanna get one for my other boat. Easy to install and made of quality materials. Good kit!
