First post on this side, did not think a new boat would need it. Just bought a brand new Crownline 242cr. It has a mag 350mpi with a bravo 3 prop and the 3rd weekend out, we started hearing a beeping. We shut everything down and looked through the manuals, after some trouble shooting, we came up with the fact the we were low on stern drive lubricants. It was at the add level as opposed to the operating level.<br /><br />We very slowly went back and filled it ( about 5 oz's ) and kept some handy on board. We went the rest of the weekend without any significant loss and does not appear to be watered down. <br /><br />Should I have a sphincter factor or is this normal additive on a new engine?<br /><br />Thanks,<br />John
