Mariner 115 inline 6 Cyl. (198?) - Zero comp & Boring question

[Wrench25]

Motor Type: Mariner 115 - inline 6 Cyliner<br />Year: Not sure - 198X<br /><br />Details,<br />I popped number 5 cylinder on the boat this year. There is a hole right through the top of the piston.<br />I have not torn the unit apart as of this point, but I am just curious if you can bore one cylinder only. It does not look like I scored the cylinder walls too bad, and a .010" bore would clean it up.<br />Can I bore the one bad cylinder only (0.010" Over), and re-ring the remaing 5 cylinders?<br /><br />Thanks in advance.

Wrench25 <br />for more info give more info, mod# ser#. <br /><br />It can be done that way, if you blew a hole in the center of the piston look for an air leak in the intake, or a carb problem on that cyl~r. I have done a bike or two that had this problem and just honed the cyl~r new piston and rings, and away you go.<br />Richard
