A nested sump housing combines transmission mounting, oil containment, and water sprayers to cut part count, lower temperatures, and save space.
A nested oil sump and transmission housing with integrated water sprayers cuts parts and package size while lowering oil temperatures.
Vertical exhaust manifold gathers gas from parallel cylinders and mounts a catalyst unit on its lateral surface to reduce engine width.
Segmented flexible ducts and robotic arms capture exhaust gases while minimizing wind-induced structural instability.
Secondary air passage directs warm engine cover air to the throttle valve inlet, preventing freezing and sticking at low temperatures.
A boat operation control system detects acceleration displacement to switch between normal and low-speed driving modes.
