Wot ... question

[krisnowicki]

1. I started running a merc 21p laser pro II prop. The boat did 49 (gps) which is great but, I was running at 4400 rpms. This prop has better hole shot then my 19p and it holds my nose down from purposing. But, is 4400 to low I don't want to lug the engine?
Manual says to run 4600 I think.
