Boat Loading and Trim
Under normal loading and operating conditions while on plane, the boat bottom is roughly parallel to the surface of the water.
Changing the loading of the boat will not change the trim angle as previously defined, but it will change the running attitude of
the boat with respect to the surface of the water. Adding weight toward the stern of the boat will cause the bow to rise. Similarly,
adding weight toward the bow of the boat will cause the bow to lower.
Changing the trim angle can compensate for a change in the running attitude of the boat. Increasing the trim angle will raise the
bow of the boat, compensating for bow heavy loading. Decreasing the trim angle will lower the bow of the boat, compensating
for stern heavy loading.
Choosing an Active Trim Profile
If Active Trim is configured properly, the normal setting for running on plane will be profile 2, 3, or 4. This allows the operator
the flexibility to change the trim angle to compensate for variations in boat loading or other operating conditions. Selecting a
higher number profile will raise the bow and selecting a lower number profile will lower the bow.
Use the preceding descriptions of trim in and trim out to help determine whether or not your boat is trimmed properly (refer to
How Trim Affects Boat Operation). In general, this means you can increase the trim profile until the bow begins to porpoise
(rise and fall), and then back off one level.
Active Trim Red Status Light
A flashing red light can indicate different things, depending on if it is a single or a double flash sequence.

Engine Synchronization (Multiple Engines)
Digital Throttle and Shift (DTS) engines have an automatic engine synchronization feature that engages automatically at
key‑up. Sync mode monitors the position of both ERC levers. If both levers are within 10% of one another, all engines
synchronize to the starboard engine's RPM. The SmartCraft system will automatically disengage sync at the last 10% of the
lever range to allow each engine the ability to reach the maximum available RPM. Sync mode cannot engage until its minimum
RPM is met.
