The Photon Marine P300-11 is a high-performance electric outboard propulsion system designed to replace conventional marine engines with a clean, modern solution. Built by Photon Marine Corporation, this conversion package delivers 135-270 kW of reliable electric power through either a single or double outboard motor depending required power.

Equipped with a 63-126 kWh lithium-ion battery, the P300-11 provides the torque and endurance needed for harbor craft, utility vessels, and workboats. Its instant throttle response and quiet operation make maneuvering safer and more comfortable

Every element of the P300-11 emphasizes efficiency and simplicity. Operators benefit from lower running costs and reduced downtime and the modular design allows for straightforward integration into existing vessels.

Charging flexibility ensures minimal disruption. The system supports compatibility with shore power, advanced charging infrastructure, and zero-emission bunkering solutions, making it adaptable to port facilities and future infrastructure upgrades.
