Note 1. SeaStar Solutions has specific steering equipment for boats that are driven aggressively, used in severe conditions or with more than 300 HP per engine.
Note 2. HC63xx PRO Cylinders are designed for all those critical high speed, single outboard boats, such as Bass, Flats & other performance boats capable of speeds in excess of 65 mph. For optimal performance we recommend to combine the use of SeaStar Pro Helms and Hoses for high speed single engine applications.
Before ordering, determine the best application for the boat based on hull design, speed, and usage. For higher speed single engine applications, Seastar recommends the use of Seastar PRO cylinders.
