inboards
Inboards are marine propulsion systems in which the engine is installed inside the hull of a vessel rather than mounted on its exterior transom. Power from the engine is transmitted to a propeller through a shaft connected to a transmission, and often a reduction gear, which allows the engine to run at higher speeds while the propeller operates efficiently at lower speeds. The propulsion arrangement is typically paired with a rudder and provides a clean deck layout with less exposure to the elements compared with outboard motors.
Common configurations include straight shaft systems, where a single shaft runs from the transmission to the
Advantages of inboards include better protection for the propulsion system, quieter operation, reduced deck clutter, and
Maintenance focuses on the cooling system, fuel system, lubrication, belts and hoses, exhaust, and regular engine
