The Gekko GTS 20 2007 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 2007 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 2007 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.
Both boats share a closely matched power ceiling — 6 hp for the Gekko GTS 20 2007 and 6 hp for the Gekko Revo 6.7 2006. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 35 gal and 38 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Gekko GTS 20 2007 is rated for 6 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 2007 could be the deciding factor.
Bottom line: Choose the Gekko GTS 20 2007 if your priority is putting more people on the water — it handles 6 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.
