Some dealers buy all of their boats with the Salt Water package, just because they are in an area the would allow for both salt and fresh water and they don't know where exactly their potential customers will be going. Right now I've got leads on two boats: one is super pimped out with a custom trailer and every bell and whistle you can think of, the other is same model/year/hrs just with a few less options. Both have the salt water package, but the "nicer" one has been used in brackish water for about 10 hrs, the other is fresh water only. They are within $3000 of each other in price.
I plan to trade it in the fall...both will have less than 200 hrs and 3 years left on engine warranty, after I'm done with them.
Thanks for the input Ben! I'd love to hear other peoples opinions...keep 'em coming.
