So I just purchased a1996 Evinrude 9.9 2-stroke remote control motor for $400. Cleaned it up, attached control harness and cables, adjusted all to run well. But what is that long black thin rubber (6') hose coming out of the motor, It spits a steady stream of water when motor is running. Motor is pissing just fine out the blow hole. What could this possibly attach to? I've search my manual and I'm at a complete loss. Help
