Operating a multi-engine offshore powerboat can be a little overwhelming at times.  That’s probably why offshore racing is the only motorsport that requires two drivers. Most offshore boats have an engine trim button built into the throttle lever handle.  We all know that the drives rarely stay perfectly even using just the BOTH button on the throttles.  Having them offset can impact handling, and can be dangerous at high speeds.  So that after a couple of moves we are all reaching to the dash to try and even them out.  Over and over again.

TrimSync is a patent pending device that monitors the trim for twin and triple engine boats, so when the operator presses the BOTH/ALL button, it will automatically adjust the drives to be in perfect alignment, every time.  You will never have to worry about how accurate your mechanical trim indicators are because TrimSync will always move the slowest drive to match the others.  There are no extra buttons or complicated operating instructions, just push the BOTH button and TrimSync does the rest.

If, for some reason, you want one drive to be at a different trim then push that drive’s trim button and it will move just as it always has. TrimSync will re-align the drive trim the next time you push the BOTH button. Just drive!

NOTE: Please specify when ordering if using Mercury Racing Engines.

TrimSync Race Edition+ includes all of the standard TrimSync features AND allows the user to program up to four preset positions that can be recalled with the push of a button. Typically, one preset would be the highest you would ever want to safely trim at speed. Another might be 2°-3° below neutral for when you encounter a wave. Race Edition+ allows you to quickly and safely trim to your “sweet spot” without having to watch the trim indicators or worry about over-trimming at high speeds.

TrimSync Race Edition is also available for trim tab / tunnel tab combinations, which greatly reduces the complexity of coordinating the position of each separately. With up to four presets the user can move the drives and tabs in unison to their individual pre-programmed positions, with a single push of a button. Of course, all presets can be easily overridden by simply pressing any other trim button, just as you would normally do.

NOTE: Please specify when ordering if using Mercury Racing Engines.

TrimSync - Diagnostics Kit Add On

MDC Diagnostic Kit for DriveSync and TrimSync systems consists of a USB cable and software to access onboard diagnostics, calibration process and fault codes. Step-by-step instructions and a built-in help command reduce the time and effort in diagnosing trim-related issues. Using a Windows 7 or later laptop you can run diagnostic tests to determine if there is an issue with the senders, wiring, or trim pump, before they become a problem on the water.

While running the boat, DriveSync and TrimSync log multiple types of errors and retain them even if the power is turned off. The Diagnostic kit allows you to access the error logs to assist in troubleshooting trim issues. For example, air in the hydraulic lines, a trim cylinder that is failing, or trim sender issue will be logged as an error letting you know which engine had the issue, and how many times it has occurred.

The Diagnostic Kit also provides a remote support capability (requires Wi-Fi) to assist with setup or troubleshooting.
