I have a 1979 Monarch bass boat with an outboard but the fuel tank is in the bilge area. When I bought it the louvered bilge vents were missing so I bought new ones but I'm not sure which way the louvers should point. So does anyone have any ideas ? And secondly it has the removable pole style bow light which I want to replace with the little short permanent style. Is there any reason I can't do this or does it have to be a certain height off the water or something ?
