Technical Reference Manual
PLEASE NOTE WHEN ORDERING: SeaStar
steering kits come with cylinder # HC5345. If your
application requires the use of a cylinder other than
HC5345, you will need to purchase all components
separately (helm, hoses, cylinder, etc.)
NOTE: When properly installed, this steering system will connect
to outboard engines with ABYC standard tilt tubes, using the
engine's tiller arm (and possibly an adapter, depending on
engine). Use only SeaStar outboard steering hoses (HO51/HO57
type) with SeaStar outboard steering systems. The use of nylon
tubing is not recommended for SeaStar outboard steering.
For SeaStar PRO, see the Pro Series Outboard Steering
section of this catalog.
Unmatched comfort and control. Only
with SeaStar steering. The world's most
popular outboard hydraulic system offers
smooth, super-efficient steering for today's
high performance hulls with single or multiple
outboards up to 600 HP combined. It's the OEM
Choice for center consoles, cruisers and more.
Applications:
Single and dual non-power-assisted outboard
engines up to 300 HP (600 combined HP
for counter-rotating duals) that have ABYC
standard engine tilt tube.
Ideal for cruisers, runabouts, center console
boats, offshore fishing boats and many more.
Suitable for speeds up to 60 MPH and dual
station use (with purchase of extra helm, hose
& fittings).
Allows independent engine tilt in dual engine
installations. Dual engines require purchase of
a tie bar kit and extra hardware.
Features:
- Patented steering lock valves.
- Low friction hydraulic steering system.
- 5 turns from lock-to-lock (single cylinder).
- Compact helm has only a 4-7/16" footprint;
needs only 3" dash hole (Tilt requires larger

NOTES:
- 1. HC5345 is optional for Single Engine ONLY applications.
DO NOT use HC5345 for twin engine applications as
operational interference may occur.
- 2. Requires One Spacer Kit HO5090 per engine.
- 3. Minimum Engine Center = 27"
- 4. May Require Extensive Cowling Modifications.
- 5. HO5030 and HO5064 come without Tie Bar.
- 6. One cylinder per engine. Must use Mercury-supplied tiller bolt
for installation.
These recommendations apply to factory stock outboards only.
Modified installations may require a higher capacity steering
system. (Cylinder volume / helm displacement = number of
turns.) If in doubt, contact Teleflex Canada technical service for
assistance. For single, dual and triple engine installations, refer
to SeaStar Manual #1.1 for detailed instructions, application information and parts diagrams. Some applications vary from
what is depicted in this catalog. Always consult SeaStar manual
for diagrams specific to your application. Use only SeaStar/
SeaStar PRO Hose or 3/8" Copper Tubing + Hoses to plumb
the system. NOTE: Interference between the cylinder and boat
can occur under certain conditions. Check installation thoroughly
throughout the full range of movement for engine tilt and trim (and
jack plate, if present).
