Starter is going out on my 1987 Sea Ray Seville Mercruiser 175 V6. I am going to order one this evening if I can figure out exactly which one I need. Never changed a starter before, is there anything I need to know before diving into this? Can anyone give me any tips and or pointers for tackling this job? I appreciate all the help I can get - I will need it. Thank you to everyone in advance.
