    Hello! I recently acquired a Poncelet 420, build in Brussels - Belgium in 1956. It is generally in good condition, stored inside a barn since 1980 (at least that's the tax plate that was on it).
    The transom is rotten but not entirely: where an extra layer of wood was added to support the outboard water got between the layers, It's not all the way through: there is still a piece of hard wood between outside and inside. There is also a crack from side to side, above the waterline. Looking for pro's and con's for repairing the transom: penetrating epoxy + thickened epoxy + glass on the outside vs. removing entire transom and replacing with fresh multiplex.
    Other options also considered.

    Remove and replace. Penetrating epoxy does nothing, thickened epoxy and glass need a sound base to adhere to. If you replace with plywood seal the edges with epoxy, glass the whole panel and fill all holes with thickened epoxy before reboring them.

    As Rumars says, there are no 'pros' and only 'cons' if you want to 'bodge' a repair - it is not a very large transom, hence it should be a fairly easy job to take the whole lot out and replace it.

    Well keep us posted. Do you plan to replace the entire transom or only the doubler under the motor?

    Entire transom, as the rot exceeds the area under the doubler.
