This 2000 Maxum 3700 SCR offers an impressive combination of space, comfort, and recent mechanical investment. Powered by twin MerCruiser 7.4L 454 Horizon V8 inboards rated at 365 HP each, both engines received extensive rebuilds in August 2025, making this a particularly attractive option for buyers looking for an older express cruiser where significant money has already been spent on the important systems.
The Maxum 3700 SCR was designed with entertaining and extended weekends aboard in mind. The spacious cockpit provides plenty of seating for family and guests, while the large cabin offers comfortable accommodations, a full galley, enclosed head, air conditioning, and generous living space.

Cabin & Comfort
The 3700 SCR offers the interior volume Maxum was known for, with a layout well suited for weekends aboard or extended cruising. Dual-zone air conditioning provides separate forward and aft climate control, while the updated refrigerator and electric head add to the boat’s onboard comfort.
The cockpit and full camper enclosure provide additional usable living space throughout much of the boating season, and the Westerbeke generator allows the boat’s major AC systems to be used while away from the dock.
A Lot of Boat for the Money
The standout feature of this Maxum is the amount of recent investment. Both 7.4L MerCruiser Horizons underwent major rebuild work in 2025, while the air conditioning systems, refrigerator, head, canvas and Isinglass, windlass, and A/C water pump have all been replaced or substantially updated since 2024.
For a buyer looking for a spacious express cruiser with traditional inboard power, generator, air conditioning, full camper canvas, and numerous recent upgrades, this 3700 SCR deserves a serious look.
I’d lead the YachtWorld/Boat Trader ad with the engine rebuilds. On a 2000 model, that is probably the single biggest thing separating this boat from competing 3700 SCRs. I also deliberately disclosed the non-working Furuno radar rather than leaving it ambiguous.
