The Gekko GTS 20 2008 vs Gekko GTX 22 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Gekko GTS 20 2008 measures 18,0 feet overall (2008), giving it roughly 16,0 additional feet of deck space compared to the Gekko GTX 22 2006 at 2,0 feet (2006). Weight tells a clearer story for trailering families: the Gekko GTS 20 2008 tips the scales at 195 lbs — 172 lbs more than the Gekko GTX 22 2006 at 23 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 375 hp, the Gekko GTS 20 2008 has a 369-hp advantage over the Gekko GTX 22 2006's 6-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Gekko GTX 22 2006 carries 35 gallons versus 28 gallons in the Gekko GTS 20 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Gekko GTX 22 2006 is rated for 6 passengers, while the Gekko GTS 20 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Gekko GTX 22 2006 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Gekko GTS 20 2008 comes in at 1 lbs per hp versus 4 lbs per hp for the Gekko GTX 22 2006. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
