Look at a 21 VLX if you are not hard core skiing. Ours throws a decent ski wake and a good surf wake with the plug n play bags. 

My comment was referring to the 21 VLX vs the VTX. 

Not a Bu' but I remember looking at these when I was looking at some MasterCrafts

Isn’t this really the same system that I already have, just in a different, smaller package?  I don’t see much different with this option.

I use a fluid extractor (vacuum pump) very similar to the ones linked in your original post. Works very well for me. Seems you are using proper methods to me. Warming the oil is the key factor in improving flow rate. Thirty minutes of run time should be more than enough to get your oil nice and warm.

and a trip to Home Depot for a couple fittings and you'll have the oil out in less than a minute - safely - using the drain hose attached to the bottom of the oil pan.
