    Help with Riva through hull rear exhaust

    Please take a look at these pictures and tell me if they look right.

    The template states 4' below the bond flange, but lining up the template with the tiedown loop puts me 4.5" from the bond flange as seen in the pictures. The circle on the diagram measures exactly 3.75" I'd hate to put the hole in the wrong place.

    Not sure about placement but run the hole saw in reverse to start the hole. Gives a clean hole for finish.

    Yes you have 1/2" or so either way to play with.

    And run hole saw in reverse to get it started.

    I set up masking tape or painters tape to get the initial grunt of the whole saw
