SeaStar Classic Tilt HH65424 Hydraulic Helm — 2.4 cu.in., ORB, Classic Tilt

High-Displacement No-Feedback Hydraulic Steering with Classic Tilt Column — Up to 350 HP

The SeaStar Classic Tilt HH65424 delivers the smooth, low-effort control of SeaStar no-feedback hydraulic steering in a classic tilt column package — with a larger 2.4 cubic inch displacement that reduces the number of lock-to-lock turns for a more direct, connected feel at the wheel. Rated for single- and multi-outboard engines up to 350 HP (or 700 HP combined for counter-rotating twins) at speeds up to 60 MPH.

The ORB (O-Ring Boss) port provides a clean, leak-resistant hose connection, and the classic tilt column adjusts to your preferred wheel angle for all-day comfort. This is the larger-displacement version of the HH65414, suited to boaters who prefer fewer turns lock-to-lock and a more responsive steering feel.

Parts Desk Insights

Best Use Case: The HH65424 is the right call when a customer specifically wants fewer turns lock-to-lock than the standard 1.7 cu.in. helms provide — common on larger centre consoles, express cruisers, and twin-outboard setups where the operator wants a more direct, responsive feel without stepping into a power-assist system. The 2.4 cu.in. displacement is noticeably more direct than the 1.7, which some customers prefer for docking and close-quarters maneuvering.

Fitment Note: Rated for up to 350 HP single outboard or 700 HP counter-rotating twins — confirm the customer’s engine configuration before recommending. The larger displacement means more fluid volume per turn, so cylinder compatibility is important — verify the cylinder’s cu.in. rating matches the helm. This helm requires a compatible hydraulic cylinder and hose to complete the system.

1.7 vs. 2.4 Displacement: The HH65414 (1.7 cu.in.) has more turns lock-to-lock and a lighter feel; the HH65424 (2.4 cu.in.) is more direct with fewer turns. For service, recommend the SeaStar HP6032 Helm Seal Kit.
