Hello everyone, we have a 2011 20 sli with a 70hp Yamaha, boat does ok with 2 or 3 people but with the grand kids getting bigger they really like being pulled on the tube, long story short looking for more power, we are looking at a new 20 sli tri-toon with a 115hp Yamaha for 30,999, or a used 2013 2075 gl, twin elliptical tubes with 50 hrs. which can be rigged with either a 115hp for 29,999 or a150hp Yamaha price not determined yet, real clean boat, have been offered 14,000 for ours on trade, I know a lot of you guys know much more than I do on the boat trade process or which boat might suit our needs better so any help or comments on how we should proceed would be much appreciated. Thanks from mascoma lake in NH
