STEERING OVERVIEW
STEERING OPTIONS BASED ON ENGINE TYPE
ALL OUTBOARDS & HYDRAULIC POWER-ASSISTED STERN DRIVES denotes Tilt Steering available for this product.
NOTE: “turns” in parentheses refers to number of steering wheel turns lock-to-lock. Higher number means lower turning effort. Lower number means quicker steering response.

SeaStar® Steering or SeaStar® P/A*
BayStar™ HK4200/4230 (O/B to 150 HP; 4.5 turns) or SeaStar® HK63XX-3/ HK6400-3 (5 turns) or SeaStar® P/A*
BayStar™ or SeaStar® HK63XX/ HK6400-3 (no hoses) or SeaStar® P/A* (order by components)

Hydraulic
(both: best for autopilots, cylinders are drive-specific)
*SeaStar® P/A is a power-assist add-on subsystem which requires presence or purchase of a complete SeaStar steering system (SeaStar PRO helms require use of SeaStar P/A Pro). NOTE: Some high performance boats/engine combinations develop instability at high speed. Instability becomes more prevalent in boats faster than 50 MPH. Dual-cable steering or SeaStar PRO systems are recommended by Dometic and engine makers for these boats. IMPORTANT: No FeedBack Steering must not be used in dual station, hydraulically, power assisted, or autopilot installations! Notes: Xtreme ™ Power assist can be use with “MOST” single cable outboard steering system to greatly reduce steering loads at the wheel. Xtreme ™ Steering cannot replace dual cable steering.
splashwell mount cylinders are offered, but require more room. Check splashwell dimensions before ordering outboard cylinders.
Outboards (without power steering): No FeedBack™ (NFB™ - mechanical), BayStar®, SeaStar® or SeaStar Pro® (hydraulic) is recommended as replacement steering for all non-power- assisted outboards. For high performance boats or other applications in which there may be engine flutter or some steering instability, dual cable NFB (4.2/ Pro Rack) mechanical systems or SeaStar PRO® hydraulic systems are recommended. For most rotary steered boats made after 1993, upgrading to NFB can be as simple as a helm and bezel change. Stern Drives & Outboards (with power steering): HPS™ High Performance Steering is recommended for power-steered stern drives and other power-assisted applications. The rack versions feature unique, coated core construction for minimal backlash at the wheel. Traditional mechanical systems (Safe-T QC® & Back Mount Rack & Pinion) may also be used for power-assisted applications. SeaStar® is recommended for all vessels using autopilots.
Will it Fit? MECHANICAL CONSIDERATIONS:
Mounting hardware for Xtreme ™ , NFB 4.2, Safe-T II helms fits the Safe-T dash cutout. NFB Rack helms fit 1984-date “The Rack” mounting holes. 1996-date “back mount” rack helms use a wider rack cable and will not work with old style rack cable (SSC124XX). HYDRAULIC CONSIDERATIONS: SeaStar helms retrofit into most boats. The SeaStar front mount cylinder is best for outboards with 22” splashwells or wider. Side/
