Scout is one of the first boatbuilders outside the Brunswick portfolio to offer Fathom.<\/p>\n<p>\u201cWe think that the 400 LXF is an ideal platform for this Fathom system,\u201d says Scout product specialist Capt. Josh \u00adSlayton. \u201cThis model is often used for entertaining and comes standard with power-hungry features including air conditioning, a gyrostabilizer, a powerful audio system, heated seats, a galley and a water heater. A silent e-power system in place of a genset offers the level of sophistication our customers expect from a Scout S-Class model, our highest level of luxury.\u201d<\/p>\n<p>Regulator Boats is also offering an e-power system. Its E-Hub Lithium Battery System, \u00adassembled from components produced by Dometic Mobile Power Solutions, is standard equipment on the new Regulator 35 model, with three 300-amp-hour house batteries replacing a genset. The E-Hub system can be charged by shore power or by triple Yamaha F350 outboards.<\/p>\n<section class=\"hydra-container\">\n<div class=\"hydra-canvas\">\n\t\t\t\t\t<img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"588\" src=\"https:\/\/i0.wp.com\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-2-1024x752.jpg?resize=800%2C588&#038;ssl=1\" class=\"hydra-image\" alt=\"Scout boat running in the river\" sizes=\"(max-width: 1400px) 100vw, 1400px\" srcset=\"https:\/\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-2-1024x752.jpg 1024w, https:\/\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-2-300x220.jpg 300w, https:\/\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-2-768x564.jpg 768w, https:\/\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-2-1536x1127.jpg 1536w, https:\/\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-2.jpg 2000w\">                <\/div><figcaption class=\"caption margin_top_xs full border_1 hydra-figcaption\">\n                <span class=\"hydra-image-caption\">Scout is one of the first boatbuilders outside the Brunswick portfolio to offer Fathom.<\/span><br \/>\n                <span class=\"article_image_credit italic margin_right_xs\">Courtesy Scout Boats<\/span><\/p>\n<\/figcaption><\/section>\n<p>Silent and odor-free operation is an obvious benefit of an e-power system over a diesel genset. E-power eliminates genset maintenance\u2014\u00adalways a headache\u2014and offers the convenience of a single liquid fuel source. Plus, genset exhaust can create a carbon monoxide safety hazard.<\/p>\n<p>Scout rigs the Navico Fathom M5000 series e-power system in place of a genset on its 377 LXF model. For charging, this system relies on shore power or the 12-volt alternators of Mercury or Yamaha outboards and provides basic \u00admonitoring and control. The Fathom 7000-X+ system offers next-level technology with real-time updates on battery-bank status and power consumption presented on the boat\u2019s MFD. The M7000-X+ series also integrates seamlessly with Mercury V-10 and V-12 Verado outboards equipped with 150-amp 12-\/48-volt alternator systems, enabling precise control over the charge source and four times the charging speed of a \u00ad12-volt alternator.<\/p>\n<p>The Fathom \u00adsystem is created using \u00adcomponents supplied by Navico brands, including Mastervolt batteries and invertor\/chargers and CZone digital switching in a complete system supplied to boatbuilders. The 400 LXF Li-Ion is equipped with four \u00adMastervolt MLI Ultra 24\/6000 lithium-\u00adiron-phosphate (\u00adLiFePO4) batteries offering 6 kW\/240 Ah of power. According to Slayton, this is enough power to run a 12,000 Btu air conditioner and a Seakeeper 4.5 \u00adcontinuously for five hours with the engines shut down. Navico claims battery life of 3,500 charge cycles, which Scout says equates to about 10 years of typical boat use. The entire system is covered by a five-year nondeclining warranty.<\/p>\n<p><strong>Read Next:<\/strong> <a href=\"https:\/\/boatingmag.com\/boats\/the-benefits-of-48-volt-charging-in-fathom-2\/\">The Benefits of 48-Volt Charging in Fathom 2.0<\/a><\/p>\n<section class=\"hydra-container\">\n<div class=\"hydra-canvas\">\n\t\t\t\t\t<img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/i0.wp.com\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-3-1024x768.jpg?resize=800%2C600&#038;ssl=1\" class=\"hydra-image\" alt=\"Lithium batteries for the Fathom system\" sizes=\"(max-width: 1400px) 100vw, 1400px\" srcset=\"https:\/\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-3-1024x768.jpg 1024w, https:\/\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-3-300x225.jpg 300w, https:\/\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-3-768x576.jpg 768w, https:\/\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-3-1536x1152.jpg 1536w, https:\/\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-3.jpg 2000w\">                <\/div><figcaption class=\"caption margin_top_xs full border_1 hydra-figcaption\">\n                <span class=\"hydra-image-caption\">Specially constructed and managed lithium batteries power the Fathom system safely and efficiently.<\/span><br \/>\n                <span class=\"article_image_credit italic margin_right_xs\">Courtesy Scout Boats<\/span><\/p>\n<\/figcaption><\/section>\n<p>Slayton explains that the Fathom e-power system weighs about the same as the generator and other components it replaces, including a 15-gallon \u00addiesel fuel tank, and fits in the same space below an aft cockpit hatch. Engine options include triple or quad Merc Verado 400\u00a0hp V-10s or twin 600 hp Verado V-12 outboards. In all cases, two of the motors are equipped with the \u00ad12-\/48-volt alternator system.<\/p>\n<p>That alternator really makes this system perform. At engine speeds above 2,500 rpm, each alternator pumps out 100 net amps (6.5 kW) to the battery bank. Charge time might vary, but from \u00adindicated zero state of charge, the system will fully charge in just two hours of run time or 3.2 hours from 120-volt AC shore power.\u00a0<\/p>\n<section class=\"hydra-container\">\n<div class=\"hydra-canvas\">\n\t\t\t\t\t<img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/i0.wp.com\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-4-1024x768.jpg?resize=800%2C600&#038;ssl=1\" class=\"hydra-image\" alt=\"Twin Mercury V-12 outboard with the Fathom system\" sizes=\"(max-width: 1400px) 100vw, 1400px\" srcset=\"https:\/\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-4-1024x768.jpg 1024w, https:\/\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-4-300x225.jpg 300w, https:\/\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-4-768x576.jpg 768w, https:\/\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-4-1536x1152.jpg 1536w, https:\/\/boatingmag.com\/wp-content\/uploads\/2025\/07\/BTG725-SPL-epower-4.jpg 2000w\">                <\/div><figcaption class=\"caption margin_top_xs full border_1 hydra-figcaption\">\n                <span class=\"hydra-image-caption\">Mercury V-12 and V-10 outboards can be fitted with high-capacity, dual-voltage 12-\/48-volt alternators to quickly recharge the Fathom system\u2019s batteries.<\/span><br \/>\n                <span class=\"article_image_credit italic margin_right_xs\">Courtesy Scout Boats<\/span><\/p>\n<\/figcaption><\/section>\n<p>There are also two selectable high-speed idle charge modes, which can be used when the boat is not underway. Extend Mode (2,000 rpm) generates 5 kW per engine (10 kW total). This mode adds approximately\u00a010 percent SOC every 15 minutes. Boost Mode (2,500 rpm) generates about\u00a013 kW total, adding\u00a010 percent SOC every 10 minutes. In either mode, the engines are electronically prevented from shifting into gear. At engine speeds below 2,000 rpm, the alternators switch to 12 volts. With Extend and Boost modes, Scout owners can remain independent at the sandbar or at anchor for a much longer \u00adperiod of time. \u00a0 Some boaters might be concerned about lithium batteries. We\u2019ve all heard about e-bikes, \u00ade-scooters and battery-powered automobiles erupting in flames. Navico says that its Mastervolt \u00adbatteries meet the ABYC E13 \u00admarine standard, are UL 1973 certified, and utilize the safest battery chemistry\u2014that is LiFePO4\u2014available. A built-in battery-management system monitors voltage, current, temperature, and state of charge to ensure that the battery is functioning safely, protecting the cells from overcharging or overdischarging. A safety disconnect will \u00adautomatically stop charging and disconnect loads if a safety event is triggered. Anecdotally, tens of thousands of recreational fishing boats now run large LiFePO4 banks with no reported safety issues.\u00a0<\/p>\n<p>Sorry, but there\u2019s no free lunch. The Navico Fathom e-power system represents a $26,000 upcharge built into the $1,138,578 base price of the Scout 400 LXF \u00adLi-Ion model, compared with a similarly equipped Scout 400 LXF model with its standard Fischer Panda 8kW \u00addiesel generator. That upcharge is about 2 percent of the boat price, which we think is a reasonable toll to pay for those seeking the technology, convenience and \u00adluxury offered by e-power.<\/p>\n<p>The post <a rel=\"nofollow\" href=\"https:\/\/boatingmag.com\/boats\/scout-400-lxf-li-ion-fathom-e-power-system\/\">Scout 400 LXF Li-Ion Fathom E-Power System<\/a> appeared first on <a rel=\"nofollow\" href=\"https:\/\/boatingmag.com\/\">Boating Mag<\/a>.<\/p>\n<\/div>\n<p> \t<BR><br \/>\n <BR><\/BR><br \/>\n    Charles Plueddeman<br \/>\n \t<BR><br \/>\n<BR><\/BR><br \/>\n<a href=\"https:\/\/boatingmag.com\/boats\/scout-400-lxf-li-ion-fathom-e-power-system\/\">Go to boatingmag<\/a><br \/>\n \t<BR><br \/>\n <BR><\/BR><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Scout 400 LXF Li-Ion Fathom E-Power System Fathom provides data monitoring, including consumption rate and time remaining.
