I have a 1990 3100 open, the suction seacook came between the two principal motor seacook. The discharge seacook it is at the port side, very close to the side stand from the port side. I belive you need to follow the hose to see where they go. probably you have snail inside the hose and that compromise the suction. Hope i can help you.
