SD 187 blower tube routing

gmtk Member Posts: 15 ✭✭
Can someone with a 187 i/o or larger model tell me how their blower/air tubing is routed? I have one tube going from the output of the blower to the vent; which is correct. But I have another tube that has one end at the front of the engine near the in-hull transducer, tube goes up and is zipped tied to the engine compartment wall; then tubing goes another 2' and just stops and is open in the engine bay.  My gut tells me it should be connected to one of the vents to allow fresh air in.  Any help is appreciated.
