could anyone tell me what merc 225 efi outboards rev to they are 1995 3lt thanks

5400 I believe, and 250's are 5800, had my 250 up there today.

thanks,my 6k is too much then

I had a modified 3 liter (97) and I ran it at the limiter 6200 for almost 1200 hrs. Yeah no typo 1200!! If your sure it is a 3 liter, it will sure wake up with a head mod and an exhaust tuner.

Also if it has the 4 butterfly intake, a 300promax ign box
