In a few hours, I'm going to purchase a Merc.150XR6. Before I place the order, I have a question. <br /><br />1. Will there be a noticeable difference between my Merc. 125 and the XR6? On my old rig I went from a 25hp to 40hp and it made all the difference in the world, speed, power and jumped right on plane. I hope a 25hp increase will be even better? <br /><br />Thanks!
