"Thank you for your service in providing me with a new heat exchanger for my 1998 Sea Ray Sundancer 240. Your part MRC860234A1 was a direct fit replacement on my 5.7L Mercruiser. My friends and I were able to remove and install the new one in less than an hour. Of course, it helps to tighten all the hose clamps before checking for leaks! :-) I will recommend you to all of my friends at the marina."
