  • 150 2/stroke - internal anodes

    Hi all.

    Am busy overhauling my motors , and have taken on the job of replacing the 8(16 for both) anodes in the water jacket. These motors are more than 10 years old so these anodes , as you can imagine , are well and truly coroded into place

    I took me about an hour to break one out, using a hammer , chisel & blow torch....

    Is there an easier way , or am i doomed to forcablly remove each one the hard way

    Rgds

    Recall reading here that if they haven't been changed in a while to just leave them alone.

      I'd just replace the ones you can get at and remove easily, no need to tear up anything. Take a wire brush to the ones you can't remove to expose some fresh metal.

        Hi Gents , , wish I knew this before I started the procedure.

        However , I am now down to about 20 Min to remove an old anode. Learing as I go along.

        What i am doing is

        Drill three 6 mm holes into the anode.Starting in the centre and then one left and right of that.

        Lesson 1 : Dont drill to deep , or else you could damage the retaining bolts hole.

        Using a die grinder and a 6mm grinding bit , grind away , VERY carefully , the left over anode.You not going to get at everything , so dont try to. You have to watch out that you do not damage the head gaskets seating area. The die grinder can " run away" with you

        Lesson 2 : Dont try and use a drill ISO die grinder. The bit is designed for a die grinder and functions a lot better at high RPM

        Using a average sized blow torch , heat up the left over pieces of the anode , and using a thin metal chisel (flat screwdriver) and hammer , chip left overs away.

        Lesson 3 : wear safety glasses ...and watch those pieces are HOT

        The above is alot of work , but the new anodes look quite cool in their slots.

        Would i do it again...NO...next time I will head Mr Graham's advise and use a wire brush
