I am about to take possession of a 2015 LS 115 hp Honda outboard with extremely low hours. I am thinking about converting it to XL shaft. Is there value in resale for the lower unit I will be removing? I know the new parts are not cheap and wanting to capture some $$ to offset the expense. What might it be worth, knowing that most conversions go from LS to XL shafts. Trying to make a good decision. I am thinking the new extension is going to run me in the neighborhood of $2K.... thanks for any comments.
