We had an 08 montana, pretty much the same vehicle. Lots of power, should pull the boat no problem. I had replaced just about every part in the front end, bearings included at less than 100K. the good thing is that the parts are cheap and easy to install yourself with a small amount of knowledge and youtube. We had about 130K when the tranny started to slip, that was more than I wanted to deal with so traded it in a couple months ago.
