RC Boat Motor Mount 25 & 19mm (Graupner Brushless Speed 600 BB)

thingiverse

Here's my design of a RC boat motor mount. It's specifically designed for a Graupner Bushless Speed 600 BB motor, but can be used with numerous other brushless and brushed motors that have a mounting diameter of 25mm. I've added slotted holes to the side walls, allowing you to secure the motor wires using cable ties. The motor angle is adjustable up to 45 degrees. When installing the screws, please note that the measured torque should be around 60Ncm, but no more than that. I printed the parts with my Anycubic Photon DLP printer, but they're designed to work with any other FDM printer as well. Here are the dimensions of the motor mount without holes for water cooling tubes: The distance between the outer corners of the side walls is 65mm, and the distance between the inner corners is 55mm. The total length is 105mm, and the total height when the motor is mounted at a 90-degree angle is 45mm. The dimensions are slightly different for the version with holes for water cooling tubes: the distance between the outer corners of the side walls is 75mm, and the distance between the inner corners is 65mm. The total length remains the same, but the total height also remains at 45mm when the motor is mounted at a 90-degree angle. The dimensions for the small version are as follows: the distance between the outer corners of the side walls is 58mm, and the distance between the inner corners is 50mm. The total length is 80mm, and the total height with a 90-degree mounted motor remains at 45mm. To assemble this motor mount, you'll need four hexagon head screws (M3x16), four hexagon nuts (M3), four washers (M3), and four hexagon head screws (M3x8) to mount the motor.
