2000 Maxum 4600 SCB: A Comprehensively Maintained Cruising Motor Yacht with Twin Cummins Power and Full Flybridge Command
Overview
The 2000 Maxum 4600 SCB represents a well-established platform in the mid-range cruising motor yacht category, offering a 45.92-foot hull designed to balance seaworthiness with comfortable extended-range cruising. Positioned at $139,995, this twin-diesel-powered vessel benefits from an extensive mechanical refresh spanning 2022 through 2025, with documented updates to propulsion systems, cooling infrastructure, seals, and interior upholstery. The boat's configuration—featuring two staterooms, two full heads, a galley with modern appliances, and a commanding flybridge with full-beam seating—targets cruising families and couples seeking overnight accommodations, entertaining space, and operational simplicity across coastal and offshore passages. The Maxum 4600 SCB hull design emphasizes stability and fuel efficiency at cruising speeds of 22 knots, with a maximum speed rating of 25 knots, supported by twin Cummins 6CTA 8.3-liter turbocharged diesel engines rated at 450 horsepower each. The 14.33-foot beam and 4-foot draft allow access to protected waters and marina basins while maintaining the buoyancy and sea-keeping characteristics required for offshore conditions. Located in Patchogue, New York, the vessel is positioned in a major cruising and charter-support hub, indicating accessibility to established service infrastructure and waterway familiarity.
Layout and Deck Design
The Maxum 4600 SCB interior layout prioritizes social spaces and sleeping accommodations across a two-stateroom, two-head configuration. The salon serves as the main gathering space, featuring a large sliding aft door that opens to the cockpit, establishing a continuous entertaining flow. An L-shaped sofa converts to sleeping berth when needed, and the salon benefits from extensive window coverage that floods the main deck with natural light. The layout includes a hi-low dinette table forward in the salon, positioned to take advantage of cabin windows and forward visibility during both entertaining and meal service. The galley is positioned upward and forward of the main salon entry, a layout choice that separates cooking operations from social seating while maintaining sight lines to the main cabin. This configuration allows the galley to function independently during food preparation without creating congestion in the primary living space. The galley counter features Corian surfaces, hardwood flooring, and a full suite of appliances including an Origo three-burner electric stove, microwave, Haier upright refrigerator-freezer combination, and integrated coffee maker, supported by hot and cold water systems and a double stainless steel sink. Forward of the galley, the master stateroom occupies the bow with a private en-suite head, creating a self-contained owner's cabin. The master berth is a queen-size island bed with storage below and hanging lockers for extended cruising wardrobe. An overhead hatch provides natural ventilation and light, while opening port lights enhance air circulation. The en-suite head features a full-size bathtub with shower stall combination, vanity with storage, and a VacuFlush electric head system, elevating the master cabin to hotel-standard comfort. The guest stateroom maintains side-by-side single berths that convert to a queen configuration, with storage under the berths and dedicated hanging lockers. A second full head serves the guest cabin and day-use purposes, also equipped with VacuFlush technology. This arrangement accommodates two couples or a family with flexibility to reconfigure sleeping arrangements. The flybridge functions as a second entertaining and command platform, featuring an expansive L-shaped lounge seating area that was reupholstered in 2024, a two-person helm seat with full command access, and an aft seating area with dedicated chairs and table. A wetbar with sink and storage extends the flybridge's hospitality function, while a bimini top with polycarbonate panels and isinglass enclosures provides weather protection without completely enclosing the space. The radar arch and helm controls position the flybridge as an active command station rather than a passive observation deck. The cockpit integrates a large sliding glass salon door, a transom door for boarding, an integrated swim platform with swim ladder, and a lazarette locker with dedicated generator access. Stainless steel bow rails, a stainless BBQ grill, and stairs to the flybridge complete the deck furniture. A Lewmar anchor windlass with helm control and foot switches provides powered ground tackle management, eliminating manual anchor work from the foredeck.
Helm and Electronics
The Maxum 4600 SCB helm station is equipped with a Garmin 7612 GPS/Radar chartplotter, a Garmin VHF marine radio, a Raymarine depthfinder, and a Raymarine autopilot, providing a coherent electronics suite for navigation, communication, and instrument redundancy. The Garmin 7612 offers integrated chart display and radar overlay capability, allowing the operator to correlate radar targets with charted hazards and traffic patterns. The Raymarine autopilot enables hands-free steering during transit, reducing operator fatigue on extended passages and improving fuel efficiency through consistent heading maintenance. The VHF radio provides both working channels for bridge-to-bridge communication and emergency hailing capability on designated frequencies. The depthfinder delivers real-time water column data, essential for safe passage in variable-depth coastal waters and for anchoring decisions. Two helm stations—the flybridge helm and the salon helm position—distribute command functions across the vessel, allowing operation from either location depending on weather, visibility, and crew preference. Hydraulic engine controls via Hynautic systems provide smooth throttle and shift actuation, while hydraulic trim tabs allow dynamic adjustment of vessel attitude for optimized fuel consumption and ride quality. Hydraulic steering ensures responsive helm feel and redundancy through a dedicated system independent of electronic controls.
Propulsion and Power Systems
Twin Cummins 6CTA 8.3-liter turbocharged diesel engines, each rated at 450 horsepower, deliver 900 total shaft horsepower to the twin-shaft propulsion system. These engines represent a well-proven platform in marine service, known for reliability and long service intervals. ZF transmissions with integrated gear oil coolers provide smooth power delivery and load management. The engine room documentation reflects comprehensive maintenance: aftercoolers replaced in 2023, all turbo gaskets and hardware replaced, turbo drain pipes renewed, thermostats replaced on both engines, heat exchangers serviced with end caps replaced, all cooling hoses renewed, engine mounts replaced, and valve adjustments completed in 2024. The fuel system includes dual fuel shut-off valves, Racor fuel filters for contamination control, and a 418-gallon fuel capacity supporting the 22-knot cruising speed and 25-knot maximum speed rating. At cruising speed, the vessel achieves efficient fuel burn relative to its displacement and power output, enabling multi-day passages without refueling. The Westebeke 13.5-kilowatt generator provides 110/220-volt AC power for onboard systems, air conditioning, appliances, and battery charging. Generator maintenance documented in 2023 and 2024 includes heat exchanger replacement, belt replacement, circulating pump replacement, raw water pump replacement, thermostat replacement, and sound box insulation replacement with repainting, indicating a commitment to generator reliability and quiet operation. Electrical systems comprise a 12-volt DC network with AGM batteries, battery parallel switches, battery chargers for both mains and genset batteries, and a 50-amp dockside shore power connection. The 110/220-volt AC system supports the galley appliances, air conditioning units, water heater, and entertainment systems.
Comfort and Climate Control
Two Marine Air 16,000 BTU reverse-cycle air conditioning units maintain cabin temperatures across the salon, staterooms, and galley, with separate thermostats allowing zone control. The reverse-cycle design provides heating capability during shoulder seasons, extending the cruising season into spring and fall. An 18-gallon water heater supplies hot water to the galley, heads, and shower, supported by a 100-gallon freshwater capacity and Tank Watch III water level monitoring system that displays tank status at the helm and in the salon. Bilge management includes a 12-volt bilge blower for ventilation, two manual/automatic 12-volt bilge pumps for water removal, and 12-volt shower sump pumps for gray water discharge. The automatic bilge pump system activates on demand, reducing operator intervention during extended periods at anchor or mooring. The salon and stateroom upholstery received modern fabric refreshment in recent years, with the flybridge seating completely reup
