2025 Kyma K7 Supercharged

The Kyma K7 Supercharged is one of the most unique watersports boats. What sets it apart is its power: a 6.2L 510 hp Indmar engine, producing 575 foot-pound of torque, connected to a jet. This, folks, is a full-on watersports machine with the draft and versatility of a jet boat.

Other jet boats in the watersports space seem to have evolved around the premise of “how do we make this jet boat make a wakesurfing wave?” However, the Kyma was built around “how do we put a jet drive into a watersports boat?” You’ll immediately notice cues taken from several segments of boats when looking at the K7. With high gunwales, wraparound cockpit seating, a large sun pad above the engine, and the arched tower, the K7 resembles a V-drive inboard wakeboat, but dual captain’s chairs at the helm bespeak a runabout’s versatility.

The jet’s biggest advantage is shallow draft, which Kyma lists at “17.5 inches under normal load.” (Typically, inboard V-drives draw 30 to 36 inches.) This allows the K7 to access shallower water, and captains don’t have to worry about bending a prop or prop shaft. Another jet benefit is steering. The K7 maneuvers well at slow speeds, especially in reverse.

Where the K7 really shines, though, is in wakesurfing. By utilizing a single jet with a downward-angled pump, Kyma eliminated the rooster-tail wash issue that often plagues other water-jet-powered wakeboats. Equipped with 3,000 pounds of onboard ballast, the Kyma can displace a lot of water with the push of a button. The waves are sizable and clean, with a pocket that provides plenty of push for a variety of riders.

Much of this is thanks to the integrated Seakeeper Ride system. Usually, these automated tabs are used to keep the boat level while running (which they can do for the K7). Kyma and Seakeeper collaborated so that the tabs deploy to create a wakesurf wave. With ballast full, some friends on board, and the Seakeeper Ride deployed, the K7’s wakesurfing waves are the best from a jet drive we’ve seen, and they’re comparable to many produced by other V-drive inboards.

High Points

Single-tap access to audio and navigation from any screen.
Tower lowers with a button push and keeps the Bimini top level. That’s great for extra protection from sun or rain.
Transom locker is big enough to hold a ton of equipment.
