The Skeeter WX 1990 2012 is a deep-V design and the Skeeter ZX 250 2010 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department - Skeeter WX 1990 2012 at 19,8 ft versus Skeeter ZX 250 2010 at 21,0 ft. At 1 825 lbs and 1 790 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 300 hp, the Skeeter ZX 250 2010 has a 75-hp advantage over the Skeeter WX 1990 2012's 225-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 52 gal and 50 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Skeeter WX 1990 2012 is rated for 6 passengers, while the Skeeter ZX 250 2010 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Skeeter WX 1990 2012 could be the deciding factor.
Bottom line: Choose the Skeeter WX 1990 2012 if your priority is putting more people on the water - it handles 6 passengers and at 19,8 ft it has the deck room to back that rating up comfortably. The Skeeter ZX 250 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
