All, Just to advise. I've recently found a couple of concerning issues with my Z18. These are relevant to the rear port side. First, I noticed a gasoline odor when raising the rear compartment cover. Upon further inspection I found the fuel line (5/8 suction line) clamp loose and stripped. Second, The tank mounting bracket was not secured. The two lower screw holes were stripped out. Plus there was a 3/4 inch gap between the bottom side of bracket and hull. The screws in the tank side were tight.
