SeaStar P/A compatibility
The P/A is designed for use in recreational marine applications in conjunction with SeaStar hydraulic steering. Optimal performance will be obtained when used with SeaStar 1.4, 1.7, 2.0 and 2.4 cu in (1000 psi) helm pumps Recommended convenience parts to be purchased NOTICE! For helm displacements greater than 2.4, twin power assist pumps must be used. Contact Dometic technical support for details.
• Dual ignition control kit, part # HA1201 • 50 amp harness fuse kit, part # HA1206
NOTICE! SeaStar nylon tube may only be used for the compensating line. Do not use SeaStar nylon tube to plumb any other portion of the steering system. NOTICE! Plan ahead. The power assist must be mounted in a “dry” location. Hose lengths must be at least 6’ (feet) between the power assist and helm pump or between the power assist and steering cylinder(s). NOTICE! When fitted with a PRO helm pump and PRO power assist there will be variations in steering effort. At the beginning of a trip the wheel will be very easy to turn and will get progressively heavier after several wheel turns are made. This is not considered a fault. NOTICE! Use only Dometic products with the P/A unit as with all SeaStar systems. Failure to do so may void your warranty. NOTICE! Retrofit kit part # HA1205 will be required to mount to a SeaStar autopilot pump to any power assist model.
