I've noticed in a lot of pictures of older Comps, the enigine house has a wooden vent on the back. Mine (1988 Comp) does not have this vent. It seems, to me, getting more ventilation in there would surely be a plus. I am curious about why some had it, and others didn't. Anyone have any ideas ? I am in the process of restoring my boat and wondered if this would be a good modification.
