The Express Mach3 OS is perfectly matched to large horsepower bay boats, offshore center consoles, and high horsepower pontoons/tri-toons. It will fit all 90hp and larger 4.75" gearcase outboards from all engine manufacturers, and Mercury® Alpha One™ and Bravo One™, and Volvo® Penta® SX sterndrives. Large diameter three blade propellers offer great mid-range fuel economy in many applications.

Would buy again and again
Color: Black, Size: 35.4 Inches
These are beautiful! I thought they’d be hard to install, but very straightforward and easy. They are quality and sturdy. I staggered the shelves and they hold a lot. Great value for the quality. I will be buying more for another room in the house.

Made my bathroom look beautiful
Color: White, Size: 15.7 Inches
The mounting and the color were excellent. I hung this in my bathroom and thought it was going to be a hard install for me. The hardware that came with this was very self explanatory. The fit was perfect and the quality was great. I would surely buy this item again in the future

Floating Shelves
Color: White, Size: 15.7 Inches, Color: White, Size: 15.7 Inches
I purchased a set of white floating shelves for my bedroom a couple months back, and I must say, they have definitely added a touch of modern elegance to the space. The installation process was surprisingly simple and straightforward, making it a breeze to set up the shelves exactly where I wanted them. The package came with all the necessary hardware, including sturdy brackets and screws, ensuring a hassle-free setup experience. I will say that the wall anchors included are not the best quality and I used a third party set. The sleek and minimalistic design of these floating shelves instantly caught my eye, and I couldn't be happier with how they complement the overall decor of my room. The clean lines and the bright white finish pop with the walls, providing a chic and uncluttered display area for my decorative items, and cherished keepsakes. They truly elevate the aesthetic appeal of any room and create an illusion of more space, which is always a bonus. However, one aspect that did disappoint me slightly was the visibility of the screws underneath the shelves. While the overall appearance is sleek and sophisticated, this minor flaw hinders the shelves from achieving a truly seamless "floating" effect. I understand that the screws are essential for stability and security, but I wish the manufacturer had found a way to conceal them better, perhaps with a cleverly designed cover or by providing white screw caps. Despite this minor setback, I still appreciate the functionality and attractiveness of these floating shelves. They have undoubtedly decluttered my living space and allowed me to proudly showcase my favorite items. I have received compliments from friends and family on how the shelves enhance the ambiance of the room. In conclusion, if you are seeking easy-to-install, stylish white floating shelves to add a contemporary touch to your home, these shelves are an excellent choice. Their seamless installation and sleek appearance make them a delightful addition to any room. Although the visible screws detract slightly from the overall aesthetic, the shelves' overall performance and elegance more than make up for it.
