    Columbia 31 new install of A-4

    If anybody has any pictures of an A-4 in a Columbia 31, I need to make up the engine bed.....I worked on one a few years ago and if I recall it was "hard mounted" without engine mounts......

    Thanks

    I have a 1970 Tartan 34C. The engine is hard mounted to two longitudinal
    molded fiberglass rails by studs that are screwed into holes drilled into
    the glass. The studs are capped by washers and nuts with small shims
    underneath as required.

    I bought some replacement studs like this from McMaster Carr. They can
    help you select them. for the ones replaced, I poured some west system epoxy strengthened with micofibers
    into the holes prior to threading the studs in.

    Hope this helps
