I think my re-ring, without a rod, cost around $400 for a new ring set and gaskets, considerably cheaper than a new motor. Did all the work myself and was able to drop the pan right in the boat so did not even have to disconnect the shaft.
What did you do about the surface of the cylinders themselves? Did you hone themm to get rid of any glaze?........i2f
