Iron Leader

First Pair of C32B Engines Installed in “Iron Leader”

North America’s first pair of 2,433 MHP C32B engines are being installed into a 70 Jarrett Bay sport fisherman “Iron Leader” in Beaufort, NC. Installed by professional marine propulsion teams from Gregory Poole and Caterpillar, Inc., the next generation of 12-cylinder diesels will be providing owners with a significant on-the-water performance boost thanks to the new sequential (3-turbo) air system.

 

The all-new Cat® C32B 2,433 MHP (2400 BHP) high-performance marine engines boast a 20% increase in power and 25% noise reduction with advanced unit injection systems at low speeds.

Three-Part Video Series

Episode One: Out With The Old

The first new 2433 mhp Cat® C32B marine engines were delivered to Jarrett Bay Boatworks, one of the world’s premier builders of customer sport fishing boats, in early 2021. In this three-episode video series, you get to go behind the scenes as the Jarrett Bay team repowers one of its own boats, Hull 48, with these faster, quieter, more powerful engines.

 In the first episode, learn more about Hull 48’s notable R&D history, discover some of the key factors to consider as you’re planning a repower and go inside the engine compartment to see how the team removes the existing four-ton engines (hint: very carefully).

 

Episode Two: Iron Leader Gets Her New Iron

New 2433 mhp Cat® C32B Engines Are the Perfect Fit

Last time on Jarrett Bay Insider, we watched the team carefully remove Iron Leader’s old engines. Now it’s time to view the process in reverse.

Tune into episode two of this three-part series to see exactly what it took to install new 2433 mhp Cat® C32B marine engines in this sport fishing vessel. You’ll also get a look at the reinstallation of the boat’s back bulkhead — a precision process to ensure everything lined up perfectly — and discover the special meaning behind Iron Leader’s name.

 

Episode Three: Sea Trials

Sport Fishing Vessel with New C32B Engines Hits the Water for the First Time

It’s the grand finale of Jarrett Bay Insider’s repower video series, and you won’t want to miss this look at the Iron Leader in action. In episodes one and two, you saw the removal of this sport fishing vessel’s old engines and the installation of the new 2433 mhp Cat® C32Bs. In episode three, it’s time for sea trials.

Watch as the newly repowered boat hits the water for the first time, go inside the all-new engine room and find out how the new engines perform right out of the gate. A significant increase in top speed, drastic reduction in smoke levels, much quieter operation, and increased stability for a great fishing platform are just a few of the rave reviews the C32B engines received from those on board.
