Hi Peggy, As I begin getting the boat ready for another season of fun, I thought I should thank you for your advice last year. We have an '87 Morgan Classic 41, and last year we decided to install an Electro-Scan. Originally, I had planned to leave the old holding tank in place, but you convinced me that it was worth the effort to remove it completely. You were right, and even though it was a lot of work, I am so happy to be rid of that foul thing! I've attached a photo of the completed job. Thanks Again! Steve
