345 Assault Engine
The first of it's kind, the 345 Assault CAT engine was developed by Indmar in cooperation with Supra Boats to perform and protect when pulling wake making sports. A specially designed air-oil separator prevents oil induction to the PCV during monster wakesurfing sessions. This Supra engine was engineered to help boat owners take full advantage of its 345 horsepower and amazing 370 ft-lbs of torque day after day on the water. Indmar along with Supra is leading wake boats to the future with a new power plant that is built for lasting performance, no matter how extreme the riding conditions.
