Brownell Boat Stands MB4BASE 18"-25" Powerboat Stand Base Only

The Brownell MB4BASE is the base-only component of Brownell's MB-4 motorboat stand, designed for powerboat storage at height ranges of 18 to 25 inches. Built for professionals and boat owners who need a reliable, heavy-duty solution for hauling out and storing powerboats on land, this base is engineered to be paired with a separately purchased Brownell MB-series top.

Designed to be placed under the flat chines of powerboats, the MB4BASE features a vertical base construction made from heavy-duty 12-gauge steel tubing with full-size 1-7/16" Acme threads for smooth, precise height adjustment — even under load. Angled iron tread plates protect pavement surfaces, while a full-length center pipe on the base provides stability and protects the threads during use and storage.

Key Features:

• Height range: 18" to 25" (46–64 cm) — base only, top sold separately
• Heavy-duty 12-gauge steel tubing construction
• Full-size 1-7/16" Acme threaded center rod for smooth adjustment under load
• Angled iron tread plates to prevent pavement damage
• Full-length center pipe for added stability and thread protection
• Totally submerged in paint — inside and out — for maximum rust resistance
• Stackable design for compact, efficient storage
• Independently tested and certified to a safe working load of 20,000 lbs (9,100 kg)
• Made in the USA with domestic American steel

Brownell recommends using a minimum of four stands per vessel, spaced one stand every 8 to 10 feet along each side of the hull, always used in conjunction with keel stands or wooden blocks under the keel. The MB4BASE is the smallest stand in the MB series and is ideal for compact powerboats requiring lower support heights. Compatible tops for this base are available separately.
