Another nice surprise was the effect on turning. ![]() I found the tabs had little effect fore and aft with the Hydro-shield already doing the job but the power trim and tilt did, the tabs still functioned for athwartships leveling. The hole shot was equivalent to putting the tabs down in normal use and came up and on plane quickly. I was also able to stay on plane at a lower rpm than with trim tabs, and it stayed on plane better in rough conditions. I could noticeably feel the lift, and the best description I can offer is it feels like a shock absorber on the transom. Conditions I would normally have to throttle back for I could easily power through without slamming. Sea trial revealed a very impressive improvement in ride in seas. Installation was very easy and instructions well written. The quality of materials in the product is very good. My initial interest when I first saw the Hydro-shield was for the prop protection feature, but was also curious what it would do for overall performance. The boat is equipped with trim tabs and jack plate. I have a 2018 Sea Pro 248 bay boat with a 300 Mercury Verado for power. I also like the fact that there is nothing mechanical that can cause issues with the Hydro-Shields." With the Hydro-Shields at 3200 RPM I am running 14.75 gallons per hour and have gained about 1 mile per hour. Without the Hydro-Shields I was running 16 gallons per hour. ![]() The boat is performing better than when the trim tabs were actually working. The boat plains immediately and with a few minutes of adjusting the trim on the motors I was able to make the boat perform better than it ever has. The difference has been amazing well above what I was anticipating. You assured me that the Hydro-Shields would dramatically enhance the performance of my boat and also help with fuel usage. A few months ago you recommended that I install Hydro-Shields to both outboards. Constant maintenance and constant cost and they rarely worked properly if at all. I had many issues with the hydraulic trim tabs from the beginning. "I purchased a used 24’ center console boat bracketed to 27’ with twin 200 Yamaha outboard engines. ![]()
