This kit is designed for use in a SeaStar, BayStar, Capilano or Hynautic
Hydraulic Steering System. SeaStar Solutions recommends that ALL work
is completed by a Qualified Marine Technician to ensure safe operation
of the vessel. Please read and adhere to ALL warnings, cautions and
notices that are outlined on this page as well as in your Owner’s Manual.

NOTICE
Failure to adhere to the torque specifications outlined below may
lead to separation of components resulting in loss of steering
control causing ejection from vessel, or collision with objects
leading to property damage, personal injury and/or death.
WARNING
It is good practice to check ALL fasteners after initial use and
regularly thereafter to ensure proper torque setting is maintained.
WARNING
Refer to your Owner’s Manual for any related notices, warnings
and/or cautions.
NOTICE
Torque values for 18-8 stainless steel and brass bolts are taken from
a torque guide by ITT Harper. All results correspond well with basic
bolt equations, using a bolt factor of 0.2 and a factor of 3/4 for a
reusable connection.
