Nauticus ST980-30 Smart Tabs 9 x 8 Self-Leveling Trim Tab Kit, 30-50 HP Boats

The Nauticus ST980-30 Smart Tabs is an automatic trim tab system built for small power boats running 30 to 50 horsepower two or four stroke engines, and is ideal for vessels from 10 feet to 22 feet in length. Unlike manual trim tab systems that rely on electric or hydraulic actuators and switches, Smart Tabs is a self-adjusting, speed-regulated system: the tabs respond automatically to changing speed and sea conditions to reduce bow rise and porpoising, helping the boat get on plane faster and ride more level with less driver input.

The trim tab planes measure 9 inches wide by 8 inches deep and are built from marine-grade stainless steel components for durability in the marine environment. The self-contained nitrogen gas actuators are sealed in chemical- and ultraviolet-resistant EPDM rubber boot seals for extended service life, and the plates include five actuator mounting positions so the system can be tuned to the specific boat. The adjustable trim plate bracket allows installation on many contoured transoms, and the kit installs on most aluminum, wood, or fiberglass transoms in under an hour. The ST980-30 kit is made in the USA and includes a complete owner's and installation manual.
