WOT question

Hi guys,
My 07' 150 EFI states on the engine plate that at WOT the revs should be at 5750. My question is where should my engine be trimmed to to achieve these revs? With my engine trimmed all the way down, I only get around 5200 rpm at full throttle. Is this normal or is there a problem? I am running a 19' prop on a 17ft hull. Is there a standard trim position in the industry where they get these rpm numbers from?. Thanks for any info.
 
Run it up to WOT and slowly tap the up trim button and watch the tach while listening to the engine speed increase. The bow will begin to rise so do it on smooth water o I doesn't porpoise. At some point the prop will be high enough to reach the recommended RPM or it will over rev as it gets to high...you'll know it by ear.
