Mercury Racing 450R/500R Performance Upgrade Kit by Kong Performance

The Kong 450R/500R upgrade kit was developed from the ground up with the goals of increased efficiency, durability, and additional power delivered to an already fantastic engine. Each part was carefully thought out and designed to work together to create an absolutely incredible performance package.

BACK TO BACK DYNO TESTING

The Kong 450R/500R kit was tested back to back on an outboard engine Dyno at Race Marine in Australia. Testing was conducted jointly by Race Marine and Motec using Kong Performance's 450R development engine. As seen in the product photos, the stock engine was first baseline tested. Next, the Kong 450R/500R kit was installed and tuned with a Motec ECU. The results were well over 150+ hp gain. These are verified and documented third party back to back dyno tests.

100% Money Back Guarantee. If you are not satisfied with the results of the Kong upgrade kit after installation, you can remove it and send back for a full refund. We are confident that you will not want to remove this package after you experience the additional power.

WATER TESTED - PROVEN RESULTS - RECORD SETTING PERFORMANCE

The first public outing with the Kong 450R kit was at the Lake of the Ozarks 2024. We installed our Kong 450R upgrade kits with Motec ECUs on two Doug Wright Powerboats Cats. Both boats ran 130+mph at the shootout and one setting a new all time outboard shootout record at 136mph.

What to expect? Massive difference in low end, mid range, and top end power. Idle, cruise, and drive just like stock. Perfect upgrade for everything from a single 450R/500R engine all the way up to 4, 5 and 6 engine boats.

Kit Includes:

-KONG Billet High Flow Nose Drive w/ SC Pulley

-KONG Billet 100mm TB with O-ring air intake connection, marine grade electronics and seals

-KONG 450R/500R High Flow Air Intake

-All bolts, clamps, and hardware for installation is included.

Installation Time: Approximately 1-2 Hours Per Engine

***Prototype parts are seen in some product photos with a raw billet finish. All production parts are anodized black for long term corrosion resistance.

MOTEC ECU (MCM112)

Easy Installation plug and play ECU kit for the Mercury Racing 450R and 500R engine!

Designed to seamlessly integrate with the Kong Performance Supercharger Upgrade kit for the 450R and 500R engine. Up to 199HP gain seen on back to back engine dyno testing conducted by Motec HQ in Australia.

The MCM112 ECU kit provides everything required for a complete replacement of the factory ECU on a range of Mercury outboard engines. The kit includes a knock sensor and knock control system, offering a significant advantage over the factory ECU.

The all-in-one ECU and adaptor unit installs quickly and easily, enabling total and instant control of all tuning parameters within minutes. Fine tune your engine for maximum power and economy or add modifications, such as Injectors, Supercharger Pulleys, NOS and Fuel Changes.

The MCM112 integrates with Mercury dash and throttle systems* and seamlessly connects with MoTeC Displays and other MoTeC accessories. It utilizes the existing wiring, fuel system, ignition and sensors** and is equally suited to single or multi-engine installations.

Along with fuel, ignition, throttle and drive trim control, this kit also supports other OE ECU features, including;

Key Start Via OE CAN
Full dash functionality including warnings and run time for maintenance
Integration with multi engine boats via CAN
Stern Leg Position Monitoring
Multi Engine Synchronization
The supplied start file contains all calibrations and settings for the sensors, port fuel injectors, ignition coils, knock control, throttle servo and cruise control. It has also been calibrated to match the OE factory fueling and ignition. This saves a significant amount of time as it shortcuts the setup process.

Drive Trim Control.
Starboard and Port Trim Tab Control.
Support of Mercury OE Systems:
- Dash Warnings supported and enabled through M1 Warning Module.
- Mercury OE DTS Systems via CAN: Throttle Lever, Crank Request, Gear Position Request, Drive Trim Up and Down Request.
