Formula 370 Super Sport: BoatTEST Review
Overview
The Formula 370SS is a premium performance cruiser measuring 38 feet 6 inches in length overall, with a beam of 10 feet 9 inches and a draft of 3 feet. Designed for versatility, it suits weekend outings, entertaining, or longer cruises. This particular model is uniquely powered by twin Ilmor 7.4 liter 483 horsepower engines integrated into the OneDrive stern drive propulsion system, blending Formula's offshore racing heritage with Ilmor's high-performance racing engine expertise.
Power and Performance
The 370SS features a 21-degree deadrise at the transom and a two-step hull design, balancing a deep-V ride with efficient planing. The Ilmor MV8 7.4 liter engines produce peak torque at 4,400 rpm, filling a power gap between 430 and 520 horsepower. During testing, the boat achieved a top speed of 53.7 miles per hour at 5,364 rpm. Cruising at 3,500 rpm yielded 31.9 miles per hour with a fuel burn of 32.7 gallons per hour, equating to one mile per gallon and a range of 191 statute miles with a 10% fuel reserve. The boat demonstrated a smooth and stable ride with minimal bow rise and consistent running attitude, handling wakes and sharp turns predictably without slipping. The Ilmor OneDrive stern drive unit, originally engineered for diesel applications, features robust gears, shafts, and hydraulic transmission housed in a larger casing for durability and quieter operation. The system carries a five-year, 500-hour factory-backed warranty, reflecting its reliability and performance.
Engine and Mechanical Features
Ilmor engines are hand-built with forged steel crankshafts, rods, and pistons, based on a cast GM 454 block but extensively engineered for durability and power. The engines utilize multiple closed cooling systems with glycol-based coolant and heat exchangers to maintain optimal temperatures and reduce corrosion. Maintenance is simplified with service points and oil filters positioned for easy access, and oil change intervals set at 75 hours for the engine and 150 hours for the stern drive unit. The OneDrive's hydraulic clutch and electromagnetic relays provide smooth operation, and the system’s design allows Formula’s paint finish to extend seamlessly onto the upper unit.
Exterior Design and Deck Features
The 370SS presents a striking profile with John Adams-designed lines and a painted hull. The stern area includes shore power, cable TV, telephone, and water hookups, along with a freshwater shower for convenience. The aft-facing transom seat converts into a large sun pad with storage lockers beneath for cockpit tables, cushions, and fenders. The cockpit features a Corian-topped console with storage, a trash can, and a cold water wet bar sink with fold-down faucet, all neatly concealed under lids. A 2.3 cubic foot Isotherm drawer-style refrigerator is integrated into a curved front cabinet. The U-shaped cockpit lounge includes a dual-height, two-piece Corian table that converts into a sun pad with filler cushions. Helm seating is comfortable and versatile, with separate fold-up seats and integrated air conditioning vents. Access to the foredeck is provided by sturdy centerline steps with grab handles, leading to a bow hatch housing a Lumar electric windlass and a polished stainless Bruce anchor with 150 feet of chain stowed in a molded tub.
Helm and Electronics
The helm is ergonomically designed with white-faced analog Ilmor gauges, including dual fuel gauges flanking a compass, a central speedometer, and tachometers below. A 12-inch Raymarine Axiom Pro display is mounted to port, while the Ilmor Merlin digital dashboard on starboard offers a programmable touchscreen interface with diagnostic capabilities and detailed joystick functionality readouts. Controls for the joystick, Bennett trim tabs, and engine throttles are conveniently positioned to starboard, alongside rocker switches for lighting and electrical systems. Communication and entertainment systems, including stereo, VHF radio, and 12-volt receptacles, are integrated into the lower helm panel.
Interior Living Spaces
Below deck, the forward cabin features a wraparound settee that converts into a berth with a dual-height, three-piece gloss finish table, creating a comfortable dining or lounging area. The flat-screen television with Blu-ray player is easily visible and mounted on the electrical panel door. The compact galley is well-appointed with ample cabinetry, a microwave, a Kenyon Seagull burner cooktop, an under-mounted stainless steel sink with a stylish faucet, and Corian countertops. Dedicated glass storage is illuminated with blue LED lighting, and soft-close drawers with dovetail joinery enhance functionality. Additional amenities include a cedar-lined hanging locker with stereo controls, a galley refrigerator, and a central vacuum system with hose storage.
Private Accommodations and Head
The wet head serves as a stand-up shower and includes an electric flush toilet, stainless steel sink with modern fixtures, an opening port light, and storage both in the vanity and a mirrored overhead cabinet. The aft cabin, located behind the companionway stairs, offers a queen-size berth with crawl-in height, storage cubbies at the foot of the berth, and a flat-screen television, providing a private and comfortable sleeping area.
Conclusion
The Formula 370SS exemplifies high-quality craftsmanship and thoughtful design, delivering the performance and handling expected from the Formula brand. The integration of twin 483 horsepower Ilmor 7.4 liter engines with the OneDrive stern drive system enhances the boat’s capabilities, providing robust power, reliability, and ease of maintenance.
