Just recently bought a 04 Nitro 882 with a Mercury 150 Xr6 2 stroke on the back, just looking for any input or advice regarding motor and maintenance, thanks!

I have a 03 Mercury 150 Xr6 and it sometimes is hard to start but it can get up and go. I have nothing bad to say about it. Enjoy

The XR6 is a hammer! The story I got about the XR series of engines started with the XR2 back in the early 80'S. Bass federation tournaments had a 150 HP cap on engines at the time. So Mercury being what they are said ok Bass guys. Here is a under rated 175 wearing 150 badges. The little 2.0 liter that could. My dad had a 18 1/2' Skeeter Starfire with an XR2 on the back. Once he got his set up dialed in that boat would run 68. Not too long after that he blew it up (oil related) while still under warranty The dealer replaced the power head with the new 2.4 liter XR4. This was supposedly a 200 in disguise. That motor needed more prop than the old XR2 and pushed the Skeeter to 74. It was a bit squirrelly at that speed, but would gladly run 70 with no problem at all. My dad fished out of that boat for several years before he retired from Bass tournament fishing. He had Zero problems out of the XR4 once they found the problem that took out the XR2. Apparently the oil injection tank was bolted down on top of the oil line restricting the flow. Totally the dealers fault. Happened when they originally rigged out the boat. The XR6 is a fuel injected 2.5 liter version. IMO it is the undisputed king of the 2 stroke 150 hp class. Keep it oiled and find a good mercury mechanic to go thru or eliminate the oil injection system. You'll get a lot of hours outta that motor. If it's set up right you'll be pleased with the speed it will provide. That old Skeeter got a lot of attention from the guys with 200's that it went by.

My back up Triton has a 1999 Mercury 150 XR6 on it. They are true work horses, I love it. As JustBass11 stated they can be hard to start when they are cold, but they WILL start...
