If in doubt, contact our Teleflex Canada technical service for assistance. (Cylinder volume / helm displacement = number of turns.)

The splashwell mount cylinder (part no. HC5380) is not suitable for use on engines fitted with factory power steering. For dual engines, use SeaStar or engine manufacturers tie bar.

For all Seastar outboard systems: Use following option A or B:

  • A) Outboard hose: order standard lengths (cannot be cut to length.) Part No. HO51__/HO57__, where last two digits = length in feet.
  • B) Copper tube: 3/8" diameter copper tube and hose kit part No. HF5508.
