When two boats share the same hull type — in this case both the Gekko GTS 20 2008 and the Gekko Revo 7.1 2008 are deep vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Gekko Revo 7.1 2008 measures 22,0 feet overall (2008), giving it roughly 4,0 additional feet of deck space compared to the Gekko GTS 20 2008 at 18,0 feet (2008). Weight tells a clearer story for trailering families: the Gekko GTS 20 2008 tips the scales at 195 lbs — 162 lbs more than the Gekko Revo 7.1 2008 at 33 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 — 375 hp for the Gekko GTS 20 2008 and 375 hp for the Gekko Revo 7.1 2008. 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 2008 carries 41 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 7.1 2008 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 7.1 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.
