/ Yanmar1610D Engine #1
Depends on what needs to be done. The 1610 does not have replaceable sleeves but could be sleeved at a machine shop. Also depends on whether you do it or have it done. Rings, rod bearings, necessary gaskets would run about $300. That is the lowest possible rebuild with your labor. If your not able to do the work why not visit some shops and get some rough estimates. In our neck of the woods there are quite a few independent shops that will work on most anything, probably are in Ga. too.
Can you elaborate a little more about the condition of the engine? Are you mechanically inclined?
I would think you could expect to take the $1400 off the asking price if you sell as is. In our area I would doubt you could get over $1500 with it blowing and using oil.
I don't know whether oversize pistons are available or not. Hoye or Fredricks could answer that. The engine would have to come out to have cylinders bored if you went with over sized pistons.
Could be you might lightly hone the cylinders, put in fresh rings and make a world of difference. Really no way to know until opened up and inspected.
