Hi,I have this OMC roughneck...people say the company was Lowe and made them for OMC...at any rate,we've been fighting over the serial number....either it's OMC S8540L 303........or OMC S 8540E 393....can anyone shed some light on these numbers....I'm guessing the 85 is the year of the boat (utility) there is no paper work with it....thx Thump
