Re: mercruiser starter replace?
Some big-block Corvettes had the same problem. I remember years ago, in my father's shop, having to partially pull the engines on some of them to replace the rear plugs. Others required drilling a two-inch hole through the inner fender housing!. Unfortunately, you can't do that with a boat. I suggest that, once you get the starter out and you repair whatever caused it to break in the first place, you replace it with a high-torque starter. They're smaller and lighter and might make the next replacement (hopefully, for the next owner) a little easier to accomplish. Good luck. Hy
