Hi. I have a 2003 Advance 257 with single Yamaha 225. I love my boat, but sometimes I feel it is underpowered, especially for the occasional tubing and skiing my kids like to do. Has anyone gone to the expense of switching to a 350? Is it possible? My dealer says my boat can't take it although the newer ones can take it. I've also thought/dreamed about trading in for either the T225 or T275. Any thoughts/insights appreciated!
