my boat is at a shop and i have no concept of hours it takes for repairs. there was an overheat and the cylinders have to be repaired (honed and bored) as well as a couple pistons need to be replaced. what is the time that goes into doing this, as well as the time it takes to remove the engine and completely overhaul to make sure there aren't any other issues. it is a bombadeer from seado with a v6 mercury engine.
