Boat once again starts
Easy install once I figured out how to reach the starter. Worked first try and my boat is starting again. I think being a contortionist would help with the install since it is under the engine and boats typically only have access from the top. It probably took me an hour to get the old one off and about 30 min to install the new.
The symptom of the broken one was a click sound when trying to start the motor, but nothing turning over. Same sound with new. Battery or a jumper.

Exactly what I needed
I didn't know my current starter was getting that bad over the years. But this is perfect, shipped on time, matched perfectly, boat started like it's never ran prior. I have owned this boat for 13 years. Very pleased
