“I Swear” is powered by twin Cummins 6BTA 5.9L 330 HP diesel engines with approximately 2,474 hours.

These engines are widely regarded as one of the best choices ever installed in vessels of this size. The 6BTA is a mechanically governed, inline 6-cylinder diesel, known for its durability, simplicity, and long service life.

Unlike newer electronically controlled engines, these Cummins are straightforward and highly serviceable—making them a favorite among experienced cruisers and Great Loop veterans. Their mechanical design allows for easier troubleshooting, reduced reliance on electronics, and confidence when cruising in remote areas.

They deliver strong, reliable performance and cruise comfortably in the 18–20 knot range, while still offering excellent efficiency at displacement speeds.
