Wasn’t 100% sure on insulation but I was able to contact Dale at Hydro shield and he included me in. Made it big difference on planning on the boat and turning was great. Still dealing with the boat wanting to pull to the right at slower speeds. All in all, I am very happy with my purchase did not seem to slow the boat down. Still clocked out 50 mile an hour.

We just added the large hydro shield to our 18’ Bayliner with a 200 Mercruiser, prior to the hydro shield it took forever to plane out and we could hardly cruise at more then 20 mph with all the large waves created by the wake boats, now it planes out within seconds and cuts waves like I feel it was meant to, changed the boat completely and it’s now such a pleasure to use.

Installed this product and it immediately solved our issues trying to get on plane and also smooting out our ride in choppy bay waters. We were going to sell our 20 foot Stingray ski boat if this hadn't worked! What a wonderful little gadget. Thank you!

Item has been installed and appears to work as advertised on my first trip in the boat.

I just put it on my second boat. Works great, Ive got a 30' and planes in seconds not a minute

it perform as it should. 3 people on board and it gets on plane like nothing.
very satisfied

TOP ARTICLE! 5 STARS!

This product is well made with Ss parts and hardware and a hard rubber compound. I put it on a new boat so cannot offer a before and after comparison but my main purpose was to protect the prop, which it will do. I can say this though my pontoon boat did get up on plan quick and handled extremely well I am which surprised me coming from a bowrider with way more power , so I happy, also the install was very easy took me 20 minutes if I had another to doing could doit in 5 minutes

Our boat just rides so smooth now and up on plane and level. The fill is drastic.

I watched a video on installation . It was very helpful . I installed it by myself ,another person would have made it easier. Before I ordered it I contacted the manufacturer to make sure I got the right one for my boat . The representative I interacted with was very helpful.

I haven’t had the chance to get out on the lake yet but it looks great and I’m hoping it will protect my lower end. My buddy in Ohio says it’s a great idea and looks like it will do the job. Pop

Quickly noticed on the first ride after installation that the boat was quicker to plane and steady when there.

Going up the river at unknown depth which got to 3’ this gave me a little ease of some protection. It seem to plan out fast as well. Was easy to install.

My second Hydro Shield and i am buying another one for my ofher boat. They bolt on fast and it works to protect your prop. I do get on plane quicker. But its hard to tell with a Yacht if i am getting better fuel economy,

I owne a Azure az240 in has a volvo penta with 300 hp and boat has always been slow out of the hole
Installed this unit and definitely help it out, now it's about half the time it took before and don't feel it hurt to pending at all
Great product, easy to install
