Isn't the LY6 "outdated" as well? MC doesn't put me in their boats anymore either.

Thanks for the debate here. I am going to talk with both dealers this week to see which one is going to offer the best deal. I will let you know how it goes.

I have an 06 x-star with the 8.1L. Couldn't be happier with this engine excellent power and have not had any issues such as the oil burning. Does not use any between oil changes

I have yet to hear one of these people that claim there were issues with the L18 come to the table with anything to support their statements... Just goes to show you that the issues were not as many as people think.
I totally agree. Break in is key but check your oil level often like any other engine and you will be fine with the L18. I would still like one.....

To be honest I have the 8.1L and it sucks the gas but really i have so much power and I love it. Yes my wallet is very thin now but it is so worth it. like in previous comments its better to have more power then not enough. and if you weight down the boat the 8.1L will still have no problem getting on plane. I run 3700LBS when we wakeboard and it will get up to 24.7 faster than any boat out on the water with weight! But one other thing remember you are buying a B.O.A.T Bust out another thousand.
