1985 POST 43 SPORTFISH CONVERTIBLE
Classic Post Sportfish with Detroit Diesel Power
Poseidon is a well-maintained 1985 Post 43 Sportfish Convertible that combines the legendary ride, fishability, and craftsmanship that made Post one of the most respected names in sportfishing. Powered by twin Detroit Diesel 671TI engines rated at 450 HP each, this vessel offers dependable performance and has benefited from major engine work and ongoing maintenance.
The current owner reports that both engines were professionally overhauled in 2001 and have accumulated approximately 500 hours since overhaul. Regular oil and filter service has been performed, and professional tune-ups have been completed by a Detroit Diesel mechanic.
The spacious interior features a comfortable salon with updated furnishings, a functional galley, private forward stateroom, bunk room accommodations, and reverse-cycle air conditioning throughout. Whether you're looking for a capable offshore fishing platform, a cruising yacht, or a liveaboard-friendly convertible, Poseidon offers exceptional value in a proven hull design.
