The Gekko Revo 6.7 2006 vs Gekko Revo 7.1 2007 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 Revo 6.7 2006 at 21,0 ft versus Gekko Revo 7.1 2007 at 22,0 ft. At 32 lbs and 33 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.
Both boats share a closely matched power ceiling — 6 hp for the Gekko Revo 6.7 2006 and 6 hp for the Gekko Revo 7.1 2007. 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. Fuel capacity breaks the other way: the Gekko Revo 7.1 2007 carries 45 gallons versus 38 gallons in the Gekko Revo 6.7 2006. 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 Revo 7.1 2007 is rated for 12 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 Revo 7.1 2007 could be the deciding factor.
Bottom line: Choose the Gekko Revo 7.1 2007 if your priority is putting more people on the water — it handles 12 passengers and at 22,0 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.
