Description

The SeaStar Pro Front Mount Outboard Cylinders have keyed support brackets to prevent racking of the cylinder, providing a more solid feel and more robust bushings. They are suited for critical high-speed, single-powered outboard boats, such as Bass, Flats, combo Race/Ski, and other performance-oriented boats capable of speeds in excess of 65 mph. These systems require the use of a SeaStar Pro helm and reinforced Kevlar hoses only (1500 psi). All cylinders ending in '3' have been updated and fit the same applications as prior models. Improvements include updated styling, a more robust barrel, new sealing systems and materials with excellent resistance to compression set, and new adjustable stainless steel O-ring fittings (ORB).
