I asked the same question. It's the 8 holes down lower on the mid section. As you increase the throttle more water sprays out those holes. They are exhust holes but also for the water exit from the cycle. The water goes up the water tube into the head and exit out the head into the exhust section.
where does the water from the water pump exit, on this model, i have a 1963 3hp 3302s that i am not sure if its pumping water.
