What RPM should I be turning?

[mstrbass]

I have heard differing opinnions on what the R's should be on 03 200 HPDI- The manual says 5500 I have heard other say 5800 with no problems. I am still under warranty-- if I consistently run over 55 will this void the warranty. I have an 519 running a 25 prop I have just had a hard time getting dialed in. Any help appreciated.

The rev limiter is set at 6150.... The motors are now rated for 6K... 5800 is great.
