  • Page 2: Notice To Installer

    Installation of this product will require electronic calibration. This calibration must not be attempted by anyone other than the Original Equipment Manufacturer (OEM) or a Mercury technician trained in Digital Throttle and Shift systems (DTS) at an authorized Mercury dealership. Improper installation and calibration of the DTS product will result in a system which is inoperable or unsafe for use.
  • Page 3: Selecting Accessories For Your Outboard

    Genuine Mercury Precision or Quicksilver Accessories have been specifically designed and tested for this outboard Some accessories not manufactured or sold by Mercury Marine are not designed to be safely used with this outboard or outboard operating system. Acquire and read the installation, operation, and maintenance manuals for all selected accessories.
  • Page 4: Determining Recommended Outboard Mounting Height

    200/225/250/275 VERADO 4-STROKE Determining Recommended Outboard Mounting Height 66.0 cm (26 in.) 63.5 cm (25 in.) 60.9 cm (24 in.) 58.4 cm (23 in.) 56.0 cm (22 in.) 53.3 cm (21 in.) 50.8 cm (20 in.) 48.2 cm (19 in.) ob01470 The solid line is recommended to determine the outboard mounting height.
  • Page 5: Installing Outboard

    200/225/250/275 VERADO 4-STROKE Increasing the mounting height will usually: • Increase top speed • Increase boat stability • Cause propeller to break loose during planing or turning Installing Outboard Installation Specifications 4241 Minimum transom opening Engine center line for dual engine - 66.0 cm (26 in.) Minimum Transom Opening Single engine 99.0 cm (39 in.)
  • Page 6: Drilling Outboard Mounting Holes

    200/225/250/275 VERADO 4-STROKE MAXIMUM STATIC WATERLINE The static waterline, with boat at rest, must be below the "MAX STATIC WATERLINE" mark on the idle relief grommet (located at the rear of the outboard) when the outboard is fully tilted in/down. If waterline is above "MAX STATIC WATERLINE" mark, adjust boat load forward or increase (raise) outboard mounting height to correctly place mark above waterline.
  • Page 7: Lifting Outboard

    200/225/250/275 VERADO 4-STROKE 2. Place masking tape directly onto the boat where the mounting holes will be drilled to help keep the fiberglass from chipping. 3973 3. Using the drill guide holes on the transom drilling fixture, drill four 13 mm (17/32 in.) holes perpendicular to and through the transom.
  • Page 8: Fastening Outboard
