-The only time I've ever seen a MR-1 engine smoke is when it is overfilled with oil (which is actually a common mistake on this dry-sump engine)
-Look for it to hit 8000 rpms at WOT at around 50-52 mph as pwcpro said. If it does that I say you can skip the compression check on this ski.
-Look at the metal plate the drive shaft passes through for signs of leakage......just had a recent post about that problem which is not uncommon on the VX. Shouldn't be much water in the hull unless you plow the nose. I think the VX has a siphon type of bilge pump, so you shouldn't see much water after a ride, but an inch or so is normal.
-If used in salt, really spend some time with a good flash light looking for corrosion.
-Get a maintenance history
-The VX is the most reliable and fuel efficient ski on the market. Not too much that can go wrong with this model. You have to work to screw it up.
