Hi all,
I'm the fourth owner of an 89 Conbrio that had Heatercraft equipment installed at some point. I have ripped out the heat exchanger and plumbing for the shower, but noticed a blower in the bilge that was not factory equipment. It was connected to some PVC pipe/ductwork that vents at the driver's feet all the way from the transom.

Anyone have experience with early Heatercraft modifications and if they included blowers/duct work?

Thanks,
John
