Baystar Hydraulic Cylinder:

The Seastar/Baystar front mount (bullhorn) hydraulic Cylinder has been specifically designed and manufactured to increase feel and control of high performance outboard powered vessels that have a high level of wear and tear and are used frequently.

Key features of the cylinder include, heavier duty pivot plate bushes that reduce wear in harsh conditions and longer cylinder rod bushes which create a better seal on the end gland. The cylinder is more rigid due to the addition of the key ways on the support rod and support brackets. The patented ‘pivot’ mount design, utilized on the Pro Cylinder, guarantees continuous smooth, comfortable steering, and maximum efficiency
