1999 Grand Banks 38 Eastbay EX “BALMY”

The Caterpillar 3100 series engines dominated the marine industry in the early 1990s. These four-stroke, in-line six-cylinder powerplants outperformed any other engine at the time. Their reputation was supported by an outstanding service support system. The 3126TA debuted in late 1995, replacing the 3116 with higher horsepower and slightly larger displacement. The 3116 and 3126 were often compared because both are in-line six-cylinder engines with a similar appearance; however, the 3116 has 1.1 liters per cylinder (6.6L displacement). The model number 3116 translates to (3100 series/ 1.1 liters per cylinder, 6-cylinder), and the 3126 has 1.2 liters per 6 cylinders that equals (7.2L displacement). Grand Banks offered the mechanical 3126TA from 1996 to 2002, and it was a huge success due to its dimensions and available horsepower ratings. From 2003 onward, the 3126's fuel system became electronically controlled, and it was reclassified as the 3126B. Caterpillar changed its model identification in 2006, renaming the engine the C-7, and production continued until 2009.

In a world that's two-thirds liquid, you need a rock-solid engine. There's a lot of history inherent in every Cat engine. It's a history of over 75 years of diesel engine progress. Caterpillar engine development is about tighter tolerances, advanced materials, and sophisticated component designs that maximize combustion efficiency. There's a lot of value in Cat engines. No matter how many technical advances it incorporates, Caterpillar has always stayed true to diesel power's core advantages: higher power, lower fuel consumption, reliability, durability, and ease of service.

The performance data cannot be guaranteed due to load conditions and sea state; these are only estimates

• Sharp entry forward keeps pounding to a minimum
• No deep forefoot to cause bow steering and/ or broaching
• V-shape is carried all the way to the transom, which results in a stable platform
• Design factors make the hull travel straight over seas with moderate steering effort
• Handling characteristics are a major safety advantage when running down waves or entering rough inlets
• A high chine forward and spray strips knock down spray, adds lift and reduces wetted surface
• Dry boat, reduced resistance, greater speed, and increased economy
• A widely flared forward topsides creates buoyancy and reduces the potential for burying the bow
• At planing speeds hull gains stability and minimizes rolling
• High-dead-rise V-shape is inherently more stable.
• The V shape allows the hull to bank in a turn, not roll outward like a round- or flat-bottomed hull.
• At displacement speeds the deep v hull has more draft than the typical planing hull, so it behaves more like a displacement hull
