Howdy folks, as you can see I am new..to the forum, and would like to become a knowledgeable Aquasport owner. I have always admired the lines of the 170, and now, later in life I own one.Mine came with a 1988 OMC Sea Drive..,but will change it out for a 2006 Mercury 4 stroke 90HP....is this a mistake? Is their a motor that would perform weight to ratio better? Thanks for any help
