I am going to replace a leaky cowl vent (actually it only leaks because one of the screw holes is stripped out- so the vent is really OK) and I was thinking about putting one of the solar ventilation fans in as a replacement. Has anyone done this and is it a good idea?? My only reason is to keep air circulating whent it's raining or when underway and the hatches are closed. Thanks for the advice!Jack ManningS/V Victim of FateAtlantic CIty, NJ
