Replacing starter on BF225?

Has anyone replaced their starter? It looks like it’s doable in the water but any first hand knowledge would be awesome.

The symptom I’m having is my stb engine acts like the battery is dead, it started doing it more and more lately. Switching to the port battery has no effect (emergency join on, stb battery off). I’ve checked all the cables and nothing is corroded or loose so assume it’s the starter starting to go. Any thoughts or advice would be appreciated.

Never done it - but there are a few really great people on the marineeingine.com Honda forum that would be able to answer that for you.
