Featuring IP56 waterproofing and a rugged galvanic build, it excels in saltwater environments. Its advanced speed controller and protective features ensure safe, quiet, and long-lasting performance, making it the ultimate upgrade for DIY boaters seeking power, durability, and efficiency. ## Description S400-48v has been designed for dinghies and sailboats up to 4 tons. It is 2700 watt input power and 180lb thrust.S400 high-efficiency contributes to more thrust, greater speed and ultra-long operating time and superior range. S400 includes a power switch, a speed controller and premium battery cables with a quick connector for safe and convenient appliance.S400 adopts unique brushless technology, which distinguish it from competition.Other trolling motors use conventional commutator brushes which eventually wear out, consume additional power and generate unnecessary heat. S400 brushless electric motors use an electronic controller instead, providing these significant advantages: Efficiency values is significantly higher 30%~60% Much higher torque values at lower battery currents 5 times longer service life and no periodic maintenance required Less noise, cooler operation and reduced battery consumption Specifications Maximum thrust: 180 pound Input power:2700WMaximum efficiency:65% Volts:48VMaximum current:56AmpMaximum proper speed:1800RPMMaximum torque:12 N.MShaft: Stainless steel, standard length 36”(If need 10” or 42", leave message, no cost.

Battery Instruction (battery not included)Four 12V batteries or two 24V batteries series connection Review: Easy to integrate DIY - The kit does come with all of the smaller things you need to get these running, including: * Prop (mine came with a spare) * The waterproof switch (I did not end up using this) * Battery terminal connectors * A starter control interface (potentiometer) The motors themselves seem to deliver. I wish I had some more scientific tools to measure how powerful they are, but a pair of them push my 10 ton catamaran ~3.5 knots. The kit is a good example of the best way that OEMs can package things in a way for a hobbyist: everything you need to get it *working*, but ready to integrate/replace as needed. Things like using standard Anderson connectors and the potentiometer are examples of using easy-to-use interfaces for integration. The manufacture is easy to contact, friendly, and is happy to answer technical questions about the product. My only criticism would be the gauge size of the wire. For pulling a max of 56 amps, the wires should be larger. In the end I used my own wire (6 awg) in place of the provided cables (with the exception of the cables inside the shaft). ## Features - Electric motor with a speed controller and a power switch with IP56 waterproof grade, suitable for boats to 4.0 tons. - Higher efficiency, achieve 65% efficiency, 30-60% higher than brushed motors and 100-200% higher than gasoline engine. - Much quieter than same power gasoline engine and half to one third the weight. - Motor Controller protects motor, battery and user: Low-Voltage protection, overheating protection, stall protection, sudden start protection, and reverse polarity protection. - Rugged engineering, sealed motor, galvanic design, sacrificial anode for trouble-free saltwater operation. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01FXDNXF2 | | Brand | Caroute | | Brand Name | Caroute | | Customer Reviews | 5.0 5.0 out of 5 stars (1) | | Date First Available | May 20, 2016 | | Engine Type | Electric | | Fuel Type | electric | | Item Package Dimensions L x W x H | 52 x 21 x 7 inches | | Item Weight | 29 Pounds | | Manufacturer | Caroute | | Material | nylon,alumnium,stainless steel | | Maximum Horsepower | 2700 Watts | | Mounting Type | Engine Mount, Transom Mount | | Operation Mode | Electric | | Package Weight | 29 Pounds | | Recommended Uses For Product | For Sail Boats, For Salt Water | | UPC | 798220315416 | | Voltage | 48 Volts | ## Product Details - **Brand:** Caroute - **Engine Type:** Electric - **Item Weight:** 29 Pounds - **Material:** nylon,alumnium,stainless steel - **Operation Mode:** Electric ## Images ![S400-48V 180LB Electric Boat Trolling Motor with Speed Controller 180 Pound Large Thrust Saltwater for DIY - Image 1](https://m.media-amazon.com/images/I/61bmR8sRMuL.jpg) ![S400-48V 180LB Electric Boat Trolling Motor with Speed Controller 180 Pound Large Thrust Saltwater for DIY - Image 2](https://m.media-amazon.com/images/I/41egsKTeVdL.jpg) ![S400-48V 180LB Electric Boat Trolling Motor with Speed Controller 180 Pound Large Thrust Saltwater for DIY - Image 3](https://m.media-amazon.com/images/I/41nGtUC4GyL.jpg) ![S400-48V 180LB Electric Boat Trolling Motor with Speed Controller 180 Pound Large Thrust Saltwater for DIY - Image 4](https://m.media-amazon.com/images/I/41xoWwLa35L.jpg) ![S400-48V 180LB Electric Boat Trolling Motor with Speed Controller 180 Pound Large Thrust Saltwater for DIY - Image 5](https://m.media-amazon.com/images/I/412V0O55XgL.jpg) ## Questions & Answers **Q: What is the diameter of the motor housing** A: 101mm ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to integrate DIY *by K***N on February 18, 2018* The kit does come with all of the smaller things you need to get these running, including: * Prop (mine came with a spare) * The waterproof switch (I did not end up using this) * Battery terminal connectors * A starter control interface (potentiometer) The motors themselves seem to deliver.
