New Formula Boat Test | Affordable 26' Dayboat | Engine Overheating - 2/5/2026

TESTED AT SPEED The Formula 360 Crossover Bowrider Outboard blends bowrider seating with real overnight capability, including a stand-up head and aft cabin berth. As tested with triple Mercury Verado outboards, she reached 63.7 mph and ran comfortably in the mid-40s. Walk-through access, defined cockpit zones, and joystick piloting make her easy to manage at speed and around docks.

TENDER FIRST Built as the smallest model in Nimbus’ Tender line, at 26’2”, she carries a full walkaround deck, convertible cockpit seating, and a two-person berth below. She features a stepped hull, multiple seating and sunbed conversions, and a compact cabin for two. Power is a single outboard from 200 to 300 hp, with a standard bow thruster and cruising speeds in the mid-20-knot range.
 

SEAKEEPER STABILIZED This 2022 Azimut Atlantis 45 is powered by twin Volvo IPS 650s with under 200 engine hours and is equipped with Seakeeper stabilization, joystick control with dynamic positioning, and a bow thruster. The layout includes two staterooms, two heads, a full galley, and multiple outdoor seating and sunpad areas. Features include a hydraulic swim platform, tender garage, retractable sunroof, air-conditioned helm, and an upgraded 11 kW generator.
 

ALWAYS CONNECTED Siren Marine has been monitoring boats remotely since 2011, sending alerts on location, bilge activity, batteries, and more. With Yamaha now integrating Siren directly into its outboard control systems, engine data like fuel levels and system anomalies can be transmitted straight to a phone or tablet. It’s a closer look at how connected boating is evolving.
 

NOT THE ENGINE A Yamaha outboard keeps tripping an overheat alarm and refusing wide-open throttle, despite sensors, impeller, and thermostat all checking out. The problem turns out not to be inside the engine at all. This walkthrough shows how engine mounting height quietly affected cooling water at speed, and why a small adjustment unlocked full RPM.
