Hey Franco, Great boat I used to own a year2000 1800 - 2001 saw some improvements but vinyl was a touch dodgy on occasion. check the seams on the back to back seats, specifically the bottom of the seat where your ass goes!
Is that the 4.3 carb (190hp) or MPI (210hp at the prop)? the carb does fine but with 6 people and some gear it really starts to struggle, you'll probably want to think about re-propping to 21 pitch stainless 3/4 or even 5 blade if the cash is available. the 3.0 litre is really a poor engine choice in my opinion as it has veyr little guts and sounds like a tractor under load.
Check the dash for any corrosion as that was a small concern around then, other then that get a dealer look at it... all being good, buy it! 8)
p.s No its still an SR... but with Snap-in carpets
