I am ready to cut out the tiller hole in the transom but note that the dimensions recommended are 3 inches high and 3 1/4 inches wide, but the mark I made from the rudder opening is only 2 inches high. Any recommendations for final fit of the tiller? Do I start an inch higher than the marks I made on the transom or maybe split the difference and just center the 2 inches in the 3 inch opening? Since the tiller movement allows for some vertical activity I don't want to wait until I have a tiller in hand to decide and possibly need to make additional modifications.
Thanks for any recommendations.
Mike
