1999 Tiara 4100 Open Boat in Manistee, MI 49660 US

1999 Tiara 4100 Open

Asking Price: $249,999

Freshwater-exclusive, meticulously maintained, and powered by one of the most respected diesel packages of its era, this 1999 Tiara 4100 Open represents a rare opportunity to own a truly turn-key Great Lakes sport cruiser.

Powered by twin Caterpillar 3208 diesel inboards rated at 435 horsepower each, this 4100 Open has accumulated just 1,830 original freshwater hours and delivers the proven reliability, mechanical simplicity, and exceptional longevity that have made the CAT 3208 a favorite among experienced boaters for decades. Power is transferred through Twin Disc MG-5061 transmissions equipped with factory trolling valves, allowing precise low-speed control for salmon trolling and effortless maneuvering around the dock.

Freshwater-exclusive since new and never chartered, this Tiara has benefited from attentive ownership and climate-controlled offseason storage. The vessel's impressive care is evident throughout, from the clean engine room to the updated upholstery and soft goods, which continue to present beautifully today.

One of the most telling indicators of this vessel's ownership history is the relationship between the engine and generator hours. While the twin Caterpillar 3208 diesels show 1,830 original freshwater hours, the 9kW Onan generator has accumulated only 190 original hours. Combined with the boat's Great Lakes fishing pedigree and factory-equipped trolling valves, the hour profile strongly suggests a lifetime of day fishing and cruising rather than extended overnight use.

Experienced diesel buyers will appreciate that this hour profile reflects consistent use rather than prolonged inactivity. The remarkably low generator hours, coupled with the vessel's fishing-focused equipment and freshwater history, suggest much of its operating life was spent underway on the Great Lakes rather than sitting idle at the dock or relying heavily on generator-powered accommodations.

The spacious cockpit is purpose-built for serious Great Lakes fishing while remaining equally comfortable for entertaining family and friends. A fiberglass hardtop provides protection from the elements, while the helm is enclosed with premium EZ2CY panels forward and roll-up Isinglass aft, offering excellent visibility, weather protection, and year-round preservation of the cockpit upholstery and soft goods.

Electronics have been thoughtfully updated with a Garmin 8610 multifunction display installed in Spring 2025, complemented by radar and autopilot for confident navigation whether making an offshore run before sunrise or cruising home at day's end.
