If you have any questions about safe installation or operation of this system, contact Dometic Marine. Please don’t guess. 1.1 Explanation of symbols The symbols below are used throughout this publication to alert you to potential hazards involved with the operation and installation of this product.
• Know and obey all applicable federal, state, and municipal laws and regulations that govern boating in your area. Dometic recommends all boat operators take a boating safety course. • Never operate a boat while under the influence of drugs or alcohol.
– refer also to those instructions. • Do not substitute any component of the system. Dometic parts are rigorously engineered and tested to ensure system integrity. Substitution of components may compromise safety, performance, and reliability.
1.4 Safety labels The labels shown below are found on the i7X00 actuators. WARNING! The labels below should call attention to the possible hazards associated with the equipment shown later in this manual. Figure 1-1. Actuator decal, PID# 277045. Figure 1-2. Actuator decal sheet, PID# 277044.
2 System Overview 2.1 System description SeaStar i7X00 is an electromechanical system that replaces a traditional cable-operated engine remote control with an electronic control. Shift and throttle settings are sent over a serial data network to electro-mechanical actuators, where they are converted to cable motion. The elimination of mechanical cables to the control head simplifies multi-station installations, especially when a station is installed onto a flybridge or tower that is removed for shipping.

3 System Operation 3.1 Before each use WARNING! Failure to adhere to these warnings may result in loss of boat control, leading to possible ejection from vessel; causing property damage, personal injury and/or death. 1. Check your steering system. If your vessel has a hydraulic steering system, ensure that the fluid level is correct.
3.2 First time use WARNING! Be very cautious when first engaging the gears to establish that forward is truly forward and reverse is truly reverse. A quick in-and-out of gear test is recommended. Ensure that the boat is clear of all obstacles forward and aft before conducting this test.

ENGINE TRIM CONTROL (OPTIONAL): Provides simultaneous trim control of all engines. LEVER POSITION INDICATORS NEUTRAL INDICATOR LAMPS: These lamps have four states: Steady green – engine is in neutral Slow flashing green (0.5s on, 0.5s off) – Neutral Throttle Warmup is engaged Very slow flashing green (1s on, 2s off) –...

NEUTRAL THROTTLE WARMUP (NTW): NTW allows you to control engine throttle without gear engagement, so that you can warm up your engines at a higher RPM. A slow flashing green neutral indicator lamp tells you that NTW is engaged for the corresponding engine.

POWER TRAIN SYNC (PTS) BUTTON AND LAMP: PTS synchronizes engines and transmissions so that the port lever controls shift and throttle of all engines. The lamp adjacent to the Sync button indicates PTS status. A steady blue lamp means PTS is engaged. To engage Power Train Sync: •...
3.3.2 Identification – Single lever (STM) ENGINE TRIM CONTROL (OPTIONAL) LEVER POSITION INDICATOR INDICATOR DIMMING FEATURE: When the control head is active, pressing SEL repeatedly will cycle through the available indicator brightness levels. NEUTRAL INDICATOR LAMP: This lamp has four states: Steady green –...

SHIFT DETENT THROTTLE FRICTION Figure 3-7. 3.3.3 Lever adjustment The control lever feel can be adjusted by means of adjusting screws on the forward face of the control head. • The friction drag on the lever is adjusted with the throttle friction adjuster screw (see figure 3-4 or figure 3-7).
3.3.4 Station selection and station select protection The way in which you activate a control station depends on whether the Station Select Protection (SSP) feature has been enabled. SSP prevents unauthorized or inadvertent activation of a control head and can only be enabled by an authorized dealer.
3.3.5 Two-lever sync When enabled on a dual lever control, this feature will synchronize engine speeds on multiple engines when both levers are in forward gear and within 5% throttle of each other. The feature requires engine RPM feedback (not all vessels will be so equipped) and can only be enabled or disabled by an authorized dealer.
4 System Faults and Hazards Should a fault occur, it will be communicated to the user though the control head LEDs. Section 4.1 defines the types of hazards you may experience with the system and how the system will handle each. NOTICE! When a serious fault occurs, consider your options.
4.2 Manual override WARNING! Manual override of shift and throttle controls may severely limit your boat control. It should only be used in an emergency, and if you are unable to call for assistance. Proceed with extreme caution. Always wear a PDF and lanyard.

Neutral Start Protection Override In the event that an actuator fails in gear the neutral start protection function of the i7X00 actuator can be overridden. To override neutral start protection depress the “N” button on the control head, hold it for 5 seconds and then start the engine with the button still depressed.
5 Maintenance WARNING! Following the routine maintenance schedules outlined below will ensure years of service from your I7X00 shift and throttle system, as well as keep you and your passengers safe from the dangers that are present on and off the water. 5.0.1 Owner(s) (end users) Prior to every use (see Section 3.1 for further details):...
