[Randy Duck]

I have a 2001 Mercury 225 efi. Want come up on plane until 2500 rpms. After it breaks 2500, it runs fine. Have change primer bulb, fuel filter, injectors have been cleaned, new battery. Is not throwing any codes. Same prop as always. Any ideas?

Not sure if you are in fresh or salt water.

Check your bottom for barnacles or growth

Check your bilge for excessive water or any other newly added extra weight

Check that your prop is not spinning loose from the rubber hub (spun prop)
