Yep’ , the green stick is in the water intake port, the red stick is in water discharge. The opening on the very back end is the underwater engine exhaust. Inside the leg of the motor there are two water tubes going up to the power head, one is a water supply the other a water return If you look up under the flywheel these tubes may be visible where they connect to the power head. Because this water circulation system has no mechanical pump but rely on pressure and vacuum these tubes must be intact and air tight for the system to work properly.
