    '04 HO missing/low rpm's

    Ok, I bought a 2004 Ranger 521vx with a '04 225 Evinrude HO back in April and it ain't ran very good since I got it. I have gone from a 27 tempest to a 25 fury and it still won't get over 5400 rpm on top end. I checked the plugs and they were filthy. I changed those and that thing will come to life now like no boat I have ever owned on hole shot. Only problem is now, at idle it misses pretty bad and misses a little while running. Plug wires are good and secure, so that is out. What do y'all think I got going on and will it hurt to run it until I can get it to the shop to get it looked at? Thanks in advance, Jason

    Did you index the plugs?

    Sounds like it may need a de-carb and clean the exhaust pressure sensor.

    Yes, the dealer showed me how to index them. I guess I am going to have to break down and take it to them to look at. I have done what little I know to try. I just hope it isn't anything too major.
