3 Wire Senders, w/Can Bus


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.

DriveSync 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 DriveSync 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 DriveSync 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. DriveSync will re-align the drive trim the next time you push the BOTH button. Just drive!

Race Edition has all the functionality of DriveSync plus the ability to have a recall button at the helm that will return the drives up to two preset positions (typically neutral). The preset positions are set by the customer and can be easily changed whenever they want. This is the same system that Team Gone Again uses on their 388 Skater.

TrimSync

3 Wire Trim Senders

The latest generation offshore performance catamarans are attaining speeds that were unimaginable a short time ago.  Operating these boats requires skill and concentration so MDC is working to help reduce the complexity so that the operator can focus on safely driving the boat.

Trim tabs are used on control the boats attitude for varying speeds and water conditions.  Unlike V-bottoms, the trim tabs on a catamaran should be even and are not used to control side-to-side lean.  To that end,  MDC developed TrimSync specifically for performance catamarans.  TrimSync monitors the position of the trim tabs each time they are moved and then corrects them to be even to ensure the safest possible ride.  The entire process is automatic and all the operator needs to do is press the trim button and TrimSync takes care of the rest.   With TrimSync the operator can focus on driving and not have to monitor the tab indicators to make sure they are even.  TrimSync is compatible with all engine/drive combinations and works with both OEM and aftermarket trim senders.

CRASHBOX, 1 PER ENGINE


Taking the "crash" out of Crashbox!

Extreme horsepower requires a robust drivetrain and the SCS Crashbox has proven to be virtually indestructible behind even the most powerful engines available today.  The challenge is that a Crashbox will not shift in, or out of gear with the engine running.  Even with the engine off it is frequently necessary to "tap" the starter several times until the gears mesh.  Needless to say, this can makes docking very challenging and stressful.

MDC has developed a simple and effective solution that unlike others, does not require any modifications to the boat or re-positioning of the engines.  Leveraging our purpose-built ECM and shift sensors we have automated the entire shift process so that the operator can simply move the shift lever and the ECM will stop the engine, tap the starter until the gears mesh and then re-start the engine.

The entire process occurs nearly as fast as you can move the shift lever.  Simple, single-handed shifting in and out of gear.  Plus, Shift Control will allow you to skip neutral and shift from forward directly into reverse and back for easy docking.  Shift Control is compatible with all marine engines, including diesel.

DriveGuardian NXT

221-1030

DriveGuardian NXT

DriveGuardian NXT is a patented device that improves the reliability of your NXT transmissions and drives. DriveGuardian reduces the torque spikes that are created each time the propeller becomes aerated or exits, and then re-enters the water after hitting a wave. These spikes are generated by the inertia of the rotating engine components and have been measured to be 2X-4X the actual torque output of the engine. These torque spikes far exceed the manufacturer’s torque rating for the NXT transmission and drive, which can lead to broken gears and twisted shafts. DriveGuardian is a torque-limiting clutch that absorbs the damaging torque spikes and protects your entire drivetrain. DriveGuardian has been proven on the racecourse with numerous National and World Championships in offshore powerboat racing.

Prior to shipment, each DriveGuardian is mounted to a specially built dyno and load tested to ensure they meet strict manufacturing standards. Your DriveGuardian is then calibrated for your specific engine and drive combination.

DriveGuardian is manufactured using billet aluminum housings and Kevlar clutch plates. The clutch plates are replaceable and the typical rebuild interval for an offshore performance application is 500-600 hours. DriveGuardian NXT retains the OEM damper plate and is a direct bolt-on with no additional modifications required. Includes a 1-year Manufacturer Warranty.

Make sure to fill out this calibration questionnaire when ordering.

DriveGuardian SCS Crashbox, Top Mount Starter

DriveGuardian SCS is a patented device that improves the reliability of your drives. DriveGuardian reduces the torque spikes that are created each time the propeller becomes aerated or exits, and then re-enters the water after hitting a wave. These spikes are generated by the inertia of the rotating engine components and have been measured to be 2X-4X the actual torque output of the engine. While the SCS Crashbox has been proven to be nearly indestructible but these torque spikes can easily exceed the ratings of your drive and lead to broken gears and twisted shafts. DriveGuardian is a torque-limiting clutch that absorbs the damaging torque spikes and protects your entire drivetrain. DriveGuardian has been proven on the racecourse with numerous National and World offshore powerboat racing Championships.

Prior to shipment, each DriveGuardian is mounted to a specially built dyno and load tested to ensure they meet strict manufacturing standards. Your DriveGuardian is then calibrated for your specific engine and drive combination.

DriveGuardian is manufactured using billet aluminum housings, Kevlar clutch plates and include a heavy duty 8-spring damper plate. DriveGuardian replaces the factory flywheel and damper plate assembly and is available for either top or bottom mount starters. Standard units are neutral balance for crankshafts with two-piece rear main seals. Other combinations are available upon request. Installation is a direct bolt-on with no additional modifications required. Includes a 1-year Manufacturer Warranty.

DriveGuardian SSM is a patented device that improves the reliability of your transmissions and drives.

These spikes are generated by the inertia of the rotating engine components and have been measured to be 2X-4X the actual torque output of the engine. These torque spikes can easily exceed the ratings of your drivetrain components and lead to overheated transmissions, broken gears and twisted shafts.

DriveGuardian, Bravo

221-1015

Replaces Stock Coupler

DriveGuardian is a patented device that reduces the leading cause of pitted/broken gears and twisted shafts in Bravo sterndrives. DriveGuardian replaces the factory Bravo rubber coupler with a multi-plate torque-limiting clutch that is calibrated to your specific application. The cause of many gear and shaft failures is the enormous torque spike that is generated each time the propeller either partially or fully leaves the water, and then is re-submerged. These spikes are generated by the inertia of the rotating engine components and can be 2X-4X the actual torque output of the engine. Each spike lasts only a fraction of a second and throttling alone cannot eliminate them. Every spike causes stress to the gears and shafts which greatly reduces their usable life.

DriveGuardian has been proven on the racecourse with numerous National and World Championships in offshore powerboat racing.

Prior to shipment, each DriveGuardian is mounted to a specially built dyno and load tested to ensure they meet strict manufacturing standards. Your DriveGuardian is then calibrated for your specific engine and drive combination.
