Some of those peculiar ratings had to do with a chenge in HP ratings. Part of the reason Mercury was faster historically was they rated their HP at the propshaft, while OMC was rated at the crankshaft. That meant the OMC's propshaft HP [PSHP] was less than advertised. 235 fell to 175, 140 to 110, 115 to 88, stuff like that. The 48 could have been the former 55 or 60, whatever they peaked the rated HP of the loop twin at.
