The Gekko GTS 20 2008 vs Gekko Revo 6.7 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.
On paper these two are close siblings in the size department — Gekko GTS 20 2008 at 18,0 ft versus Gekko Revo 6.7 2006 at 21,0 ft. Weight tells a clearer story for trailering families: the Gekko GTS 20 2008 tips the scales at 195 lbs — 163 lbs more than the Gekko Revo 6.7 2006 at 32 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 Revo 6.7 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 Revo 6.7 2006 carries 38 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 GTS 20 2008 is rated for 5 passengers, while the Gekko Revo 6.7 2006 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Gekko GTS 20 2008 could be the deciding factor.
Bottom line: Choose the Gekko GTS 20 2008 if your priority is putting more people on the water — it handles 5 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Gekko Revo 6.7 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
