Low Speed Trim
In controlled speed zones, many boats start to fall off plane as speed
decreases, thereby reducing visibility. In automatic control or manual control,
lowered trim tabs keep the boat on plane longer at lower speeds while maintaining
a level boat attitude.
Special Digital Throttle and Shift (DTS) Features
The DTS system features several alternate operational modes for the electronic remote
control (ERC) levers. Most of the listed features can be operated simultaneously and can
help you with:
• Warming the engines.
• Trolling the vessel.
• Docking the vessel.
• Synchronizing the engines.
• Dual helm station transfer.
