Im about to buy a 2009 330 with the 496/Bravo III setup. The dealer said they ran the serial numbers and confirmed they are Seacore. However, when I asked a while back if the engines had a freshwater flush kit, the answer was 'no'. I just watched a Mercruiser video and in it, they mentioned the freshwater flush kit came as part of the Seacore package. So, I'll contact the dealer and ask for clarity. In the meantime, any info anyone may have would be greatly appreciated. May save us airfare on the trip to check it out next week.
