View Full Version : Merc 2.5/280 Rebuild question- Exhaust Port Matching worth the effort?

I'm rebuilding my 280 with a fresh set of wizard pistons and spacer and when I broke her down I noticed the sleeves are just a little smaller than the exhaust opening.

Is it worth buying a air dremil (sp?) and good carbide bit to match the ports or is it a waste of time, money or both?

This is my primitive drawing, so bare with me...

Please leave it as is. The chances of screwing it up are extremely high.

It will be left untouched. Thanks
