New member. Long time reader. I have a 1436 jon boat with a 25hp evinrude short shaft. Looking to pick up a 1648 and would like to keep my 25hp motor. It runs like a top. Will I regret getting the 15 inch tramson and keeping my motor or should I sell it and get the 20 inch tramson? Looking at the alumacraft 1648 mv ncs. Thanks.
