yanmar 1700 block busted

[vulcan101]

ok,water froze and busted side of block.started to use it today and checked all fluids and was low on water .when i filled the radiator water poured out the left side of block almost as fast as i poured it in.should i try to get it welded and if so will it hold up?or should i just replace engine.sure hope someone has other ideas as this has been a great little workhorse with almost no problems.

Weld 'er up. Nickel rod.

Weld it, I bought my 2310 with a welded block, saved almost a grand, I had to put a head gasket in it after about 50 hrs but with over 150 more hrs no problem, I've had the tractor four years and I am very pleased. I had dealt with welded blocks on old ford N models so I understood what it should look like. If your not comfortable with welding it yourself find a good welder. Just my humble opinion

Heat the block up with a torch and nickel weld. Try to wrap it up after welding so that it cools slowly. This will help prevent future cracking. Another way to fix it is call stitching. That is when you drill a hole at the start of the crack and plug it with a Loc-Tited bolt. The next bolt is overlapped into the first and so on until you reach the end of the crack. This does work as I had two cylinder heads off my old 350 Mercruiser done. One thing about cracked blocks you need to know. Usually if the outside cracks, so does the inside. My block was busted internally and externally. I had to junk it. I did buy the boat this way for cheap money. So a new motor was figured in on the price already.

thanks all for the responses.i was hoping the welding would be the best bet.i think i will try to find a good welder in my area and let him have a go at the block rather than me try it.

If the weld won't do it.. try brazing. Cast iron accepts that with alot less problems than weld. I've seen tons of antique engines with as much brass as cast iron on the sides of the block when bad things happened.

I am suprised it got cold enough in Bamma to freeze crack your block.. The old boys down there use to drain the water out before a frost. Now a days, I would just use a tiny bit of antifreeze. Try welding and see.....or maybe you can find a good used engine or a good block.

It has been getting right nippy here is Bama this winter. Of course it will be 70 degrees one day and by the weekend we have a low of 16. The current temp is 25 deg.

Maybe more than a bit of antifreeze?
