I didn’t see this part answered.

The copilot controls the throttle so the pilot can keep both hands on the wheel. I’ve also been told when the boat gets airborne the copilot feathers the throttle to keep the prop from over speed or damage to the engine. I can’t remember which exactly. It could be both.
