POWER ASSIST STEERING
NOTE: These recommendations apply to factory stock sterndrives only. Modified instalations may require a higher capacity steering system. If
in doubt, contact our technical service for assistance.
1. SeaStar 1.7 helms are the standard recommendation for both non-power and power steered applications.
2. SeaStar 2.4 helms can be specified for power steered applications where faster steering response is desired. Review the Application Guide
on the previous page for recommendations.
3. For SeaStar 1.7 systems, use 3/8” diameter nylon tubing (Part No. HT5xxx). For SeaStar 2.4 systems or any system using the HC5332
cylinder, use the following option: (A) Outboard Hose: hoses must be ordered in standard lengths. They cannot be cut to length.
OR
(B) Copper tube: 3/8” diameter copper tube and hose kit (Part No. HF5508).
