225HP

Mercury’s 225 EFI outboards’ specs vary widely since several different models of the 225 were made, including a 3.0L two-stroke and a 3.4L four-stroke V6.

Still, they all have their quirks, including the limp mode randomly coming up on the four strokes. Moreover, the toxic relationship between fuel injection and the two-stroke configuration makes repairing the 3.0L quite challenging. Whichever one you have, a Mercury 225 EFI manual will help you get them in order no matter the issue.

Indeed, the step-by-step instructions and wiring diagrams found in a Mercury 225 service manual will significantly increase your chances of correctly troubleshooting the EFI system. Moreover, following the manufacturer’s recommended maintenance schedule will ensure you avoid any unnecessary problems.

Mercury’s 225 EFI outboards are considered some of the best-sounding V6 outboards out there, and a good repair manual will help you keep their singing uninterrupted.
