Outboard Engine Cylinder Boring
One of the cylinder boring services that we specialize in is outboard engines. This is sometimes referred to as “blind hole” boring which refers to the inability to bore straight through the holes in the block. This means you have to bore they cylinder blind and requires more machining skill than a most cylinder boring shops have. Well, we've got those skills and we have been doing it for almost 40 years!
We've found that many outboard engine owners don’t even know that this term exists because blind hole boring (in outboard engines) is such a specialized process that many mechanics and marine dealers would rather just sell you a new power-head. There are many reasons for this, but usually the reason ranges between the shop not having the tooling and/or expertise and wanting to make more money on the sale of a new power-head.
2-Stroke & 4-Stroke Engines
Lathes are a NO NO!!! We have seen and heard of people doing such things, but you know better… Right? If anybody tries to put your cylinder in a lath to bore it out, RUN the other way. A lathe has its purpose, but there is a reason that a specialized machine called a boring bar exists. Trying to lathe a cylinder causes all kinds of issues ranging from out of roundness to cylinder wall gouges and scratches.
Cylinder Sleeving (Re-Sleeving)
Have you already bored out your block to the max? Oversize pistons not available for your Engine? Maybe, another shop messed up your block when they were trying to bore it. Well, we have solutions to all of those problems. Before you go out and buy a new power-head give us a call and let our machinists re-sleeve your block today!
