LS is long shaft or 20" models (top of transom to keel).<br /><br />SS is short shaft or 15" models.<br /><br />XL is extra- long or 25" and XXL is 30".
One example is the Boston Whaler Outrage-18 of the 80s.<br /><br />Single engine. . . 25" or extra long shaft.<br /><br />Twins. . . 20" (long) shaft engines.<br /><br />5" of deadrise between center of transom and the outer portions where twins would mount.
Thanks for all the info. I will call a SC dealer south of me and see what they say. I just can't imagine two motors on a 12' boat with a 15hp max. Maybe you could order either way. I will find out.<br />Thanks again for the info.
