bought a 2009 196 for this reason... just traded in from a 1997 gt 40 ski nautique tsc1
love correct craft but 4000+ rpm for 36mph is just too much. My brother who has a 2006 196 does 3600 rpm at 36mph and has a top of 48mph and this is a 700 hr boat.
I believe the 200 body is just too wide causing too much drag. They should have thought of this during design. Also for most skiers use you actually dont need much more room than a 196 or 206 has to offer, but I know this is a very personal view, what isnt personal however is a newer ski-boat that does too many rpm resulting in less longevity and more fuel consumation, that just isn't progres in my book.
Also with the 200 with the standard engine you just don't have the top speed to pull a barefooter, while we have ample speed in the 2006 196 for that, and this is on the 330 excalibur, not the 343...
I hope they will be able to sort it out with a newer, better prop, which is the only option they have i think??
I really hope they do for you because it is a beautifull looking boat with good fit and finish I believe, really think your heater was just a snag, usually boats, cars, truks, even planes break down early in their lifespan and late.. called MTBF Mean time between failiure. HIghest when new or old...
