The generator is the reason a lot of good offshore days end early. It runs, it needs servicing, it is loud at anchor, and when it will not start you lose the air conditioning, the ice and half the reason the family came. Scout's answer on the 377 LXF is to take it out of the boat entirely and run the 120-volt systems off a lithium-ion bank instead. That single decision tells you most of what this 37-foot center console is about.
A 37-footer built around its electrical system
The 377 LXF sits in Scout's S-Class, the yard's designation for its luxury models from 33 feet up. It measures 37 feet 7 inches with an 11-foot-5 beam, draws approximately 26 inches, and comes in at 14,120 pounds dry without engines.
The hull is built with what Scout calls Carbon Epoxy Construction — carbon fiber and E-glass as the primary reinforcements in an epoxy infusion process — over the yard's dual stepped bottom. Transom deadrise is 19.5 degrees. That is worth noticing: it is flatter than the 22 degrees Scout runs on the 357 LXF and the 400 LXF. A flatter run trades some of the head-sea cushion of a deeper vee for stability and efficiency, and it is a deliberate difference between siblings rather than an accident.
The electrical architecture is the headline. Scout fits a 5,500-watt, 400-amp-hour lithium-ion battery with a battery management system, and the boat is specified to run 120-volt air conditioning and heat in the cabin and at the helm with no generator aboard. There is no diesel tank to fill, no genset to service, and no engine noise at anchor while the cabin stays cold.
Two engine packages, two different personalities
Scout publishes performance bulletins for both configurations on this hull, both tested with the Seakeeper aboard.
Triple Mercury V10 400s
Top speed of 68.0 mph at 6,411 rpm. Zero to 20 mph in 5.82 seconds, zero to 30 in 9.07 seconds. Scout marks best cruise efficiency at 4,000 rpm — 39.6 mph at 0.99 miles per gallon — and publishes an estimated range of 358 miles.
Twin Mercury V12 600s
Top speed of 67.9 mph at 6,417 rpm. Zero to 20 mph in 5.73 seconds, zero to 30 in 8.4 seconds. Best cruise sits higher up the range at 4,500 rpm — 44.4 mph at 0.98 miles per gallon — and Scout's estimated range is 354 miles.
This is an unusually clean comparison, because the two packages land within a tenth of a mile per hour of each other at the top and within four miles of each other on range. What actually separates them is engine count and cruise character. The twin V12s hold their efficiency peak at a genuinely faster cruise — 44.4 mph against 39.6 — and give you two engines to maintain instead of three, with two props to replace instead of three. The triples give you a third motor's worth of redundancy a long way from the inlet, and slightly better manners at low speed in a following sea. Scout caps the boat at 1,350 horsepower either way.
Living with it
The 377's cabin is entered through the console and it is a proper enclosed space, not a crawl-in. Scout fits a double berth, a cabin skylight, port and starboard windows, and 120-volt air conditioning and heat. The head is enclosed and finished with a porcelain vessel sink on a Corian vanity with a mirror; the marine head has electric overboard discharge into an 11.5-gallon holding tank. Fresh water capacity is 61 gallons, roughly two and a half times what the 357 LXF carries, which is the difference between rinsing gear and actually showering.
On deck, the portside swing-in boarding door with its own ladder is the feature that changes days — it is what makes swimming, diving and getting an older guest aboard from a dock or a beach straightforward. Forward of the console, a double sun deck lounge with cushions, armrests and storage underneath gives the non-fishing half of the crew somewhere real to be. Key-fob remote controlled lighting is standard, as is a Seakeeper 3 gyro with solar panels on the hardtop.
The fishing side is honest rather than maximal: a 30-gallon aerated cockpit baitwell, raw and fresh water washdown, and Scout's usual gunnel and hardtop rod provision. The summer kitchen — grill, sink, cutting board, manual slide-out cooler, seat cushion and bolster — is on the options list, and it is the option that decides whether this boat is a fishing boat that entertains or an entertaining boat that fishes.

Where it sits against the alternatives
At 37 feet 7 inches the 377 LXF shops against the Boston Whaler 380 Outrage, the Pursuit S 358 and the Grady-White 345 Freedom. Those three make their case on hull construction, helm finish and family versatility respectively. Scout's case on this particular boat is narrower and easier to test: carbon and epoxy in the laminate, a stepped bottom, and a generator-free electrical system that keeps the cabin cool without a second engine running. Go sit in the cabin at anchor on a July afternoon with the air conditioning on and listen. That is the sales pitch, and it either lands or it does not.
What Scout does not publish
Scout does not publish a dry weight with engines fitted for the 377, nor a recommended cruising horsepower. If lift capacity or slip loading matters to you, ask for the rigged figure for your specific configuration in writing rather than adding a guess to the 14,120-pound dry number.
Talk it through
The triple-400 boat and the twin-600 boat look nearly identical on paper and feel different from the helm. If you want help deciding which one suits the way you run — and what the lithium system does and does not cover — email TS@MintedYachts.com or call +1 (404) 805-9819.
