I recently aquired a 1984 20 ft Mako. The boat was beat up by the previous owner and stored for the past 2+ years outside with no cover. i spent the past few weekends working on the 89 150 Evinrude and finally got it to run. i figured there was no reason to work on the rest if the engine didn't run. There is a removable deck cover partially under the center console. The seam under your feet while standing at the controls has water leaking out. It comes out more when you put some weight on it. I removed the round cover under the console and there was water right to the top. I think it is access to the gas tank sending unit. There is another rectangle cover just up front and still under the console. I removed this and again there was water in the void where there is no floatation. I am concerned that there is water under the whole floor. Two areas of concern. The bow, just below the bump rail has a hole about 4" x 4". I guess one too many dock rams. There is also a large crack on the bottom of the front floor well. I just don't know the internals well enough to know if water entered through one of these two areas if it would eventually drain into the bilge and exit. Should I be concerned? Is there a way to test further. I was thinking of drilling a few small holes in the bottom of the hull?
