If you're going for hydraulic steering be sure to get the right helm, I went for Seastar Pro and it makes all the difference feels much tighter and more precise than the standard Seastar helm. I was quite surprised actually when Barnet fitted this helm as standard equipment instead of the Standard Seastar helm. They simply said they don't cut corners!! Fair enough!!
SeaStar Pro is the ultimate steering system for high-speed single engine outboards. As the Premier Teleflex No Feedback System, SeaStar Pro delivers uncompromising steering control! Suited for all those critical high speed outboard powered boat applications like Bass, Flats, Combo Race and Ski, and other performance boats capable of speeds in excess of 60 MPH. SeaStar PRO has steered the Bass Masters since 1994 and it's the choice of high performance outboard boat builders.
