We have a transom leak in a 2011 Sundancer 330 (the moisture readings around the transom drain plug are at 80% and are generally high across the whole transom area, around both engines and the trims). We have been advised to take out the engines and try and find the leak (described by our technician as trying to find a needle in a haystack). Taking the engines out will be costly and I was wondering whether there is a better way of trying to find where the leak is coming from so that they can target the fix (maybe without having to remove the engines). The boat is out the water right now and water is still dripping (very slowly now after 2 weeks) from the transom drain plug and we have been advised that we will need to drill some holes to let the water drain out. Again, does anyone know of a better way to get the water out of the hull once it has leaked in?
