I own a Mac 19 and would like to look at another that is/ has been sailed to see how a few things are supposed to be rigged and fitted. Mine has the inspection ports for the ballast tanks sealed with silicone (?). Dont know why. Also has an oversized keel cable. It has the original (?) Tohatsu 40 that has good compression and seems to run decently. Looks like holes were drilled in the l9wer stern area...again, dont know why. I did an impellar on it and would like to launch it and run it.
