Since this is a fairl new boat we think the dealer should have a loo see at this one. The fuel in the port rod box indicates that there could be a small leak in the fuel connections. Though since the upper deck is all the same cavity, you should have that smell in the other rod box and the rear as well. Though it may be localized and only permeation. The fuel tanks are plastic and can allow permeation at a low parts per million level. The permeation is common in plastic fuel tanks, though the smell is not overly common in BCB models. Thus we think yours deserves a good look see. Also check the bilge area for hints of trace fuel in the bilge, or on top of water there. BCB
