Default Re: Video putting a sleeve in a flathead

Doesnīt matter if you break through to water...
If you get a poor casting with a pinhole or a crack into water the sleeve with some sealer will fix it.
What you canīt do is bore it so big that you loose to much material affecting strenght between deck and mains.
