going to pick up my X-star this week i saw in the stickies the thread about buying a boat but didnt see anything specific about the 8.1L Is there anything that i should keep an eye out for on that motor before i buy is there any specific problems? Also what is the ball size for an 05 xstar.

I have an 06 X-Star with that engine and have never had any engine problems. you might have read comments that it is known to burn some oil but I have had mine almost 4 years and it has never burnt any oil, Great Engine but it does tend to burn the gas if you run it pretty hard and load the ballast down but has a huge amount of power and the sound of that engine is amazing

Depending on how you use it, you may need a prop change to get the best combination of power and fuel economy. I've heard some 8.1 engines use a little oil but I wouldn't be concerned about that, just check it every time you use it.
An '05 MC trailer for that xstar should use a 2" ball. I use a 2" drop hitch on my '07 Suburban to keep the trailer level.
Are you towing without the cover on? You may want to also consider having it shrink wrapped for the trip if it's a messy drive.
