Hynautic TK-04 Hydraulic Boat Cruiser Trim Tab Cylinder 12V/24V

The Hynautic heavy duty marine trim tabs provide the force to keep pleasure and commercial boats trim and level that is normally too great for most fiberglass nylon trim cylinders. One brass Hynautic trim cylinder provides a force equal to approximately 2.5 times that of the typical nylon cylinders. The Hynautic trim tab assembly is constructed of heavy duty brass and is built to last because it resists corrosion by eliminating all external hoses, isolating dissimilar metals, and protecting vital seals.

This Part Is Discontinued, Here Are Your Options:

1. If you have a TK-01 or TK-04 and it is rebuildable, you can purchase the Hynautic Trim Tab Cylinder Seal Kit TKS-01.
