    Mercury Tilt and Trim units

    hadn't heard of doing that - I had drilled it through and got a stainless steel valve into it after having to drill a bit more to get it in almost flush but still leaks - haven't drilled it oversize - would a machinist know what I was talking about if I showed them the unit and explained what I...
