1984 Post 43 Sportfish - "UN DIA"

Twin Detroit Diesel 6-71T | Fresh Rebuilds | Updated Electronics | Well-Maintained Classic Sportfish

"UN DIA" is a classic 1984 Post 43 Sportfish that blends timeless lines with the reliability and performance that made Post Yachts legendary. Known for their sturdy build, sharp entry, and efficient cruising speed, the Post 43 remains a sought-after platform for serious anglers and cruisers alike.

Powered by twin Detroit Diesel 6-71T engines, this vessel delivers the kind of dependable performance that only these proven workhorses can provide. Both engines have been professionally rebuilt-the port engine in 2020 (approx. 45 hours) and the starboard in 2024 (approx. 15 hours)-ensuring many more years of reliable service. The 6-71 series is renowned for its longevity, ease of maintenance, and worldwide parts availability, making this a power package trusted by boaters everywhere.

In June 2025, "UN DIA" was hauled out for fresh bottom paint, Props tuned, Prop Speed, and Cutlass Bearings replaced on both props, along with miscellaneous maintenance items to keep her in prime operating condition. While she has spent the last 16 years in saltwater, the majority of her life was enjoyed in freshwater, stored safely in a covered boathouse, contributing to her overall solid condition. You'll find her Gelcoat to be in much better condition than similar boats of her age.

At the helm, you'll find a new Simrad multifunction display featuring Radar, Plotter, and Depth Sounder, paired with a stand-alone Simrad Autopilot for precise and effortless navigation. These modern upgrades make "UN DIA" equally ready for offshore fishing trips or comfortable coastal cruising.

The Post 43 offers a practical and spacious layout-large cockpit, wide side decks, and a well-appointed salon with galley and two staterooms-ideal for weekend adventures or extended stays aboard.

Whether you're chasing tuna offshore, cruising the coast, or enjoying sunset runs with family and friends, "UN DIA" delivers the performance, pedigree, and comfort that define the Post Yachts legacy.
