      I have a 1960 Evinrude litewin 3hp that needs a power head rebuild (compression less than 30lbs). Is there a good source for piston rings? I have only been able to find NOS. It will cost $80 for four rings!

      Additionally, what else should I check while the power head is torn down?

      Thanks

        As far as piston rings go I have had great dealings with Hastings Piston rings. They are a very consistent dimensionally.
        Pleasant to deal with on the phone.

        If you don’t want to go brand new there are members here that sell NOS rings for less than 80 bucks.

            Look at the head gasket for a break between the two cylinders. It is fairly common and drops compression to about 30 pounds in both cylinders. It is caused by a slightly warped head, and the slight warpage of the aluminum head can be sanded down by placing wetordry sandpaper on a perfectly flat surface (I use the smooth steel top of my old tablesaw) and working the head across it until it’s straight. New head gasket is Sierra (or NAPA) #18-3841-2.

                P/N 378412. My OMC/BRP dealer used to carry them but now they would probably have to buy them back from Sea-Way in Seattle who bought all of their old stock.

                  I’ve used Otto (Tubs link) with good results.

                    +1 for Otto. They’ve had several unobtainium rings sets I needed
