The NEW SeaStar Outboard Steering Cylinder

SeaStar Solutions, the leader in hydraulic and mechanical marine steering, has introduced a
new outboard hydraulic cylinder featuring upgrades to the barrel, sealing system and fittings.
These upgrades are designed to keep pace with the introduction of heavier higher horsepower
engines found on today’s new boats.

…………………………………………………………………………………………………………………………………………….

FEATURES
• Independent engine tilt for twin/triple engine installations
• Easy steering
• Suitable for use with all SeaStar Helms & SeaStar Power Assist
• Varying lock to lock turn ratio, dependant on helm selection
• State of the art proprietary sealing system offers excellent resistance to repeated compression
set and is designed to better withstand the harsh environment
• Stainless steel adjustable O-Ring (ORB) fitting for easier installation

…………………………………………………………………………………………………………………………………………….

MULTIPLE ENGINE CONFIGURATION
For Single, Twin and Triple Engine Applications

Twin Engine / Single Cylinder (Uses HO6001 tie bar)Twin Engine / Dual Cylinder (Uses HO6002 tie bar)

HOW TO SELECT A FRONT MOUNT OUTBOARD STEERING SYSTEM

1)  From the installation recommendations on page 3-3 select the system configuration based on:
a) the number of engines,
b) the total power of engine(s) to be installed andc) driving use.
2)From the application guides, confirm that the Front Mount cylinder will fit your specific make, model and year of engine. Select the adapter kit for single engines or the tie bar kit for dual engines.

3)From Section 6 select the appropriate helms and accessory hardware for each steering station.

4)From Section 9 select the fitting and hose kits required for the installation.

5)Confirm that there is sufficient space available in the splashwell and dash areas for the steering components.

6)Determine if Power Assist is desired, see SeaStar Power Assist Steering to even further enhance your hydraulic steering system.

CAUTION: Not recommended for use in installations where;
a) Chopper, cleaver or surface piercing propellers are used,
b) The engine is highly elevated on the transom,
c)Engine trim tabs have been removed,
d)The boat speed exceeds 75 mph (120 km/h), or
e)The power exceeds the maximum Coast Guard or M.O.T. recommendations for the boat.

OUTBOARD INSTALLATION RECOMENDATIONS

Outboard recommendations made in this section are based on our experience with typical installations, applications and usage. Ensure you select the system which provides the best comfort versus performance. It is the boat manufacturer and the installer’s responsibility to ensure the components selected are sufficiently validated on the boat for safe and acceptable operation. DO NOT use SeaStar Solutions Steering in applications they are not intended for.

NOTES
1. SeaStar Solutions® has specific steering equipment for boats that are driven aggressively, used in severe conditions or with more than 300 HP per engine.
2. ALL ENGINES over 300 HP and all boats that are driven aggressively must use a high strength tiller bolt, kit part #HA5822. All front mount cylinders built after June 15, 2007 will have this high strength bolt included in the box. High strength tiller bolts can be identified by the marking ‘TFX – ARP’ on the head of the bolt (refer to NOTICE below).
3. HC63xx PRO Cylinders are designed for all those critical high speed, single outboard engine boats, such as Bass, Flats combo Race/Ski and other performance orientated boats capable of speeds in excess of 65 mph. For optimal performance, the use of SeaStar PRO Kevlar Steering Hoses is recommended.
4. HC6845 Tournament cylinders are designed for use with high powered fishing/sport boats. If your application calls for dual or triple outboard engines, is capable of speeds exceeding 55 mp/h and runs in open water, Tournament Cylinders should be used.
5.  Not recommended for use in installations where:
a) chopper, cleaver or surface piercing propellers are used,
b) the engine is highly elevated on the transom,
c) engine trim tabs have been removed,
d) the boat speed exceeds 75 mph (120 km/h), or
e) the power exceeds maximum Coast Guard or M.O.T. recommendations for the boat.
