I can see two black tubes around the engine to take fumes outside the boat to avoid explosions. One of them is connected to a Blower and one is just hanging out there. Was the second one supposed to be connected to a second blower? I mean does the boat has 1 blower and 2 tubes or 2 blower and 2 tubes?
The second tube is an intake only. That is where the fresh air comes in and then the blower (or just the force of air coming in) exhausts the air out of the other tube.
One tube is for the blower exhaust. The intake tube for the blower should originate down low in the bilge because that's where gas fumes will collect - at the lowest point. The 2nd black hose that isn't connected to anything is a fresh air supply.
So, just one blower. While you are in there be certain the blower tubes are open and not being pinched/collapsed by anything.
