Mayfair Hydraulics 12" High Performance After-Plane Trim Tab Kit

Mayfair Hydraulic's After-Planes are the very best, yet reasonably priced hydraulic trim tabs on the marine market today. Here are some of the features, unlike other planing devices. Mayfair Hydraulics After-Planes are manufactured from premium quality high strength aluminum alloy castings with deep-ribbed cross sections for additional strength and stress distribution. All of the external hardware is 316 series stainless steel or powder coated for increased corrosion resistance. Although transom stainless steel connections are an integral part of the Mayfair Hydraulics After-Planes, eliminating costly and bulky brackets and fittings. This results in a simpler, faster, and cleaner installation.

Each Mayfair Hydraulics After-Plane can be independently operated by dash-mounted controls. Because of the unique hydraulic system, there is no"droop" due to hydraulic leakage. The After-Planes will remain locked until the controls are again actuated. Mayfair Hydraulics After-Planes offer substantial advantages in performance, fuel economy, stability and handling. This package is for the tabs ONLY. No hoses, fittings or pumps are included.
