I have a bone stock 2004 rxp..It has only 13 hours on it,i just purchased it a week ago from the org. owner and he says he never had a problem,never took it in to the dealer..It runs only 7600 rpms and 63 mph on the factory speedo and tach.I beleive it should be 8100 rpms and 67 mph.. any ideas what might be the cause? ??? THANKS ALOT IN ADVANCE!!

Check the oil level. It is most likely over filled.

Check it warmed up and LEVEL. Put it in between the mark on the stick.

Take it to the dealer and have them do the knock sensor pigtail update and ecu flash update. Then it will run like a new ski. I had to do the same.

OH yea, I forget about that! Good point.

1.) Check Oil level.
2.) Go to dealer and see if Knock sensor update was done.

Joe,
Check the oil level as they have said. Keep it no more that half way between the two bends on the dipstick. It is best to check it on the water.

Have the knock sensor and piggy back harness update done by the dealer. That also updates the stock ECU as well.

Check the wear ring for wear.

Check the impeller rubber/plastic nose boot to make sure it is on the impeller and not sliding up the drive shaft.

If all else fails then check your SC clutch slip.

While you are at the dealer ask them if that boat has the hood latch recall. Some of the early 2004's needed an update on the hood latch.
