No local machine shops have the tooling for boring the blind cylinder holes in my Mercury 3.0L V6 two stroke block. So I can either send it off or provide the tooling. I'm not a machinist so I don't know specifically what is required, just that it costs around $2k. Maybe it's something that could be purchased used or rented?

One of the holes melted a piston so will need at least a good honing, maybe an oversize bore. The other holes could also use a good refresh on the cylinder wall surface. Haven't taken any measurements yet to determine if any boring is required.

Any machine shops worth shipping a fishing motor to? I'm in Wyoming if that makes any difference.

Thoughts? Thanks
