Hi<br /><br />I have just fitted a new Mercury 140hp to my 6 metre boat it has a 19 pitch high five prop on it that is giving me 5900 rpm and I can reach the rev limiter when I trim the engine up to the first index on the trim gauge. I am using the boat for skiing. <br /><br />Do I need to go up in pitch or change my prop.<br /><br />Thanks in advance <br /><br />Cheers
