Title: 2.5 Merc 2 Stroke Machinist Bored A Hole In The Block
Post by: GWP on October 02, 2021, 11:19:18 AM: Rebuilding my 2.5 Mercury 2 Stroke. Though ‘rebuilt’ ones show on the ‘interwebs’ they do not ACTUALLY exist when you call on them, or order them. Same with a lot of the parts.
My block was good but needed a .015 bore on one cylinder, so was doing them all, and bought a $2200 crankshaft to make basically a brand new engine.
Talked to the machinist yesterday. He let the boring tool go too deep and actually CUT A HOLE IN THE BLOCK. He was just taking it over to get it welded up.
What. The. H.E. double hockey sticks?
Good blocks are hard to come by, and while I know they get welded all the time, how pissed should I get? Discount? Free bore job?

Ummm, not understanding what he did exactly but based off my back in the day experience with dirtbikes they took the cylinder off to be bored. :dunno:

He went too deep on at least one and cut through the side of the block. Fairly thin cast aluminum.
