I just un-winterized my 2009 Stingray 18' boat with a volvo Penta 3L and volvo Penta sterndrive SX-A. The sterndrive has two boots from the sterndrive to the boat. I noticed that the top boot had 4 small streams of water coming out of it. The streams of water are coming from both the start of the boot and the end of the boot at the same place on each end. question: is that normal? the rubber boot is not weathered. Not sure what the top boot is for. Also I noticed when I killed the motor and turned off the water that the boot stream was still comming out like it was made to drain the water.Thanks for your help in advance.
