HOW TO SELECT A FRONT MOUNT OUTBOARD STEERING SYSTEM
1. From the order guide below select the system configuration based on:
a) the number of engines, and
b) the total engine power to be installed.
2. From the application guide below 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 the order guide select the appropriate helms and accessory hardware for each steering station.
4. From the order guide select the fitting and hose kits required for the installation. Note: for hoses add the distance required, in feet to the last two digits of the part number.
5. Confirm that there is sufficient space available in the splashwell and dash areas for the steering components. See WARNING.
Notes
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.
WARNING.
Operational interference of the steering cylinder/cylinder fittings and jackplates/transom/splashwell can occur under certain conditions. Check installation thoroughly throughout the full range of Motor Tilt, Jack Height and Trim before making final installation.

Notes
1. Teleflex 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. HC67xx 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 ion open water, tournament Cylinders should be used.

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 kit HO5090.
3. Minimum engine center = 27″.
4. May require extensive cowling modifications.
5. HO5030 and HO5064 comes without tie-bar.
6. One cylinder per engine. Must use Mercury supplied tiller bolt for installation.
7. Interference will occur when using a single HC5345 cylinder and HO6003 tiebar when installed in the aft hole on the steering arm.
Options include,
a) install tiebar into most forward hole (this will limit steering articulation),
b) purchase K-6 Cylinder, and tiebar kit part # HO5009. There will no be no interference when using twin HC5345 cylinders.

CYLINDER INSTALLATION
WARNING.
Operational interference of the steering cylinder/cylinder fittings and jackplates/transom/splashwell can occur under certain conditions. Check installation thoroughly throughout the full range of Motor Tilt, Jack Height and Trim before making final installation.
If interference does occur, contact:
Teleflex Canada for additional information/options.
Telephone: (604) 270-6899 or (941) 488-6744
If interference is not eliminated total steering loss can occur, causing property damage and/or personal injury.

LIQUID TIE BAR KIT
Part # HA5471-2
The Cylinder Alignment Valve will allow for the periodic required realignment of two outboard motors or rudders that are linked together with a Hydraulic Tie Bar as opposed to a solid link or Mechanical Tie Bar. Generally found on Pontoon Boats and Catamarans. Teleflex recommends the use of a mechanical tie bar when possible. There is no true substitute for a mechanical connection. The ‘Liquid Tie Bar Valve’ will require re-alignment. The frequency of re-alignment is too difficult to predict here as several application specific variables need to be taken into consideration.
