Photon Marine, a developer of high-performance electric outboard propulsion systems, and Silverback Marine, a builder of commercial aluminum vessels, have announced a groundbreaking development. Eight electric workboat configurations have been approved for funding through the California Air Resources Board (CARB) Clean Off-Road Equipment (CORE) Voucher Program.

This significant milestone marks the first inclusion of an electric outboard motor in the program, opening up new possibilities for commercial fleet operators across California. This includes ports, harbor patrol, aquaculture, research, construction, tourism, and enforcement sectors.

Starting in August, eligible operators can receive up to $240,000 in vouchers per vessel, with an additional $60,000 for small businesses and operators in disadvantaged communities. Furthermore, all applicants may receive up to $100,000 for shoreside charging infrastructure, creating a total potential incentive of $400,000.

Photon’s zero-emission propulsion system delivers 300HP peak (150HP continuous) power, providing instant torque, quiet operation, and low-maintenance performance. Paired with Silverback’s rugged aluminum hulls, the configurations are specifically designed for demanding environments.

Options include the agile 18-foot SuperCub for marina support and the 24-foot Sherpa for aquaculture, dredging, or utility work. Each vessel features Photon’s P300 electric outboard motor and fleet management software, with one or two motors and up to 126 kWh of battery storage.

Approved models include:

• Silverback Grizzly (24′) – Port ops and hydrography
• Silverback Sherpa (24′) – Patrol, transportation, logistics
• Silverback VersaBarge (24′) – Aquaculture, dredging, utilities
• Silverback SuperCub (18′) – Marinas, pump-out, training

These CORE vouchers reduce upfront costs by up to 78%, providing a significant incentive for operators to adopt electric workboat configurations. The program operates on a first-come, first-served basis. Photon and Silverback are now offering consultations to assist organizations in securing funding ahead of the August launch.
