Why Choose REV6

Every engine goes through a strict, two-stage quality control process. First, a master technician completes the build. Then, a second expert inspects it before approval. With over 50 years of combined powersports knowledge, our team ensures every motor is ready for the water.

Build Core Engine – Important Note

This listing is for a Build Core Engine. It is not a drop-in ready motor. We require a rebuildable core as the foundation for your remanufactured engine. During the process, each core is fully disassembled, inspected, machined, and rebuilt with upgraded or remanufactured parts.

Your core must be complete, free from excessive wear, cracks, or missing components. For details, review our Help Center or contact our team before ordering.
