My water inlet tube in my 1999, Volvo penta. S X Drive has a hole in it causing the sea pump to suck air ,when I separated the lower and upper units. The tube stayed in the upper unit. It looks like it just pulls right out. Can’t find it in the manual or a video for removal of the water inlet tube part number 3860252 . anyone ever have this issue before? How to pull a water inlet tube?
