- 2006/2025 Tiara Sovran 4300 — Repowered, Refit, and Ready
- Two Stateroom, Two Head Luxury Express Cruiser
- Volvo D6-440 IPS
- E4 Electronics
This is not a typical 20-year-old Tiara. This 2006 Sovran 4300 has been comprehensively repowered and modernized over the last two model years to compete head-to-head with current production express cruisers — at a fraction of the price. Between the late-model Volvo D6 IPS drivetrain, the cutting-edge Volvo E4 electronic vessel control package, a top-to-bottom electronics refresh, and a cabin that genuinely presents in 10-out-of-10 condition, this Sovran offers turn-key cruising with warranty coverage that even most new boats don’t carry.
The Tiara Sovran 4300 has long been regarded as one of the best-built American Express cruisers of its era — solid hull, balanced layout, two private staterooms, two heads, and a salon and cockpit that flow as one. What this boat brings on top of that pedigree is a modern propulsion and electronics package that simply did not exist when these hulls left Holland, Michigan.

Performance
• Cruise: 28 knots at 3000 RPM, 85% load, ~30 GPH
• Top end: 34 knots
• Notable: Cruises faster than other sisterships of this vintage, which were factory-delivered with smaller engines. The repower fundamentally changes how this boat performs.
The Repower — 2015 Volvo Penta D6-440 IPS
The heart of this refit is a fresh pair of Volvo Penta D6-440 HP engines installed in 2025 with only 100 hours, fully serviced in 2026. Pod-drive details:
• Starboard pod: Replaced new in August 2025 under Volvo factory warranty (two-year coverage in effect)
• Port pod: Resealed, shafts replaced, both pods fully serviced in 2026
• New T6 props installed 2025
The Volvo E4 System — What It Is and Why It Matters
Installed in August 2025 under Volvo Penta’s factory warranty (two-year coverage active), the EVC-E4 (Electronic Vessel Control, 4th generation) is Volvo Penta’s current-generation integrated control platform — the same architecture going into brand-new IPS yachts today. The refit included:
• All 5 new ECUs with the latest software
• Fly-by-wire digital throttles and joystick control
• Garmin digital gauges and navigation integrated to the E4 backbone
In plain terms, the E4 system is the digital nervous system that ties the engines, pods, helm controls, and displays together. It enables and supports:
• Joystick docking — move the boat in any direction, including sideways, and pivot it in its own length with one hand. Removes the intimidation from tight marinas, crosswinds, and current.
• Dynamic Positioning System (DPS) capability — the boat can hold a precise GPS location and heading hands-off, ideal for waiting on a bridge, a fuel dock, or a slip.
• Autopilot, cruise control, single-lever mode, and PowerTrim Assist built into the base E4 software.
• Full engine and drivetrain monitoring and diagnostics through a clean, modern glass-cockpit display.
• Future-proofing — the E4 platform is what Volvo is building toward for the next decade, including additional software features that can be activated over time.
For a buyer, this means you are operating a 2025-current control platform on a proven 2006 Tiara hull — with active factory warranty until August 2027.

The two-stateroom, two-head cabin presents in genuine 10-out-of-10 condition. It has been kept meticulously and is ready to step aboard and use today — no projects, no deferred cosmetics, nothing on a list. Comfort and entertainment upgrades include:
• 3 new Roku smart TVs (2025)
• Starlink installed (2025)
• New JL Audio stereo system — amps, subs, 11 speakers, replaced 2025

Summary
You are looking at a 2006 Tiara hull with a 2025/2026 drivetrain, 2025/2026 electronics, a 2025/2026 cosmetic package, and active Volvo Penta factory warranty on the pods and E4 system through August 2027. The cabin is immaculate. The boat cruises faster than her larger-engined sisters and docks like a new IPS yacht thanks to the joystick and E4 architecture.
This is a rare opportunity to own a proven American-built express cruiser with all the heavy lifting — and all the capital expenditure — already completed.
