I recently bought a 2015 Ranger 520C with a Mercury 250 Pro XS, serial number 2B112688. I'm thrilled to have the boat, but have to admit I am a little uneasy with the motor sitting that long. Of course I have the full warranty but sure hope not to have to use it. Any opinions about an engine sitting this long? I plan on breaking it in by the book, just wondering if any thing else should be a watch out. Thanks in advance.
