i have a question about liquid cooled marine engines. how does the water circulate in the head, do they have water pumps on them? i am curious because i think it would be nice to make a liquid monster truck.
There is a water pickup on the back of the boat. Most often this is part of the rudder, but sometimes it's a separate part. When the boat is moving forward the water is forced through the pickup and then into the engine.
