For I/O sterndrive boats, Hydraflex offers three hydraulic compact and easy-to-install
2-lines steering systems. The cylinders of these systems are available in three models,
type IO-B133, IO-133S and IO-133L, for the application on the various brand and type of
sterndrive engines. The helm pumps of these systems are the standard LD serie pump. To get
a steering system with less steering effort required but more steering turns lock-to-lock,
we recommend the application of LD25 helm pump model, with the application of LD35 helm
pump model, you will have more steering effort required to turn the wheel, but less turns
lock-to-lock.
Like every Hydraflex 2-lines steering system, the sterndrive systems are very easy to
install and to purge, require minimum space around the engines for application, and they
are designed to provide many years of smooth steering for your boat.
