5-6 K are the wot numbers for that engine wether being 2 or 4 strokes ones. You're already at the very limit assuming lightly loaded and with you alone. Going 1 pitch less will give much more that 120 rpm needed to be top, will over rev....

Get some small weight off that boat and you'll be at 6 K.

Turn idle screw CCW to a point that when shifting forward you hear a dry clak gear engament and engine dosen't die when at load, adjust as needed to achieve this cond.
