I have a 228 and did mine last summer.At the stern of my boat I have 2 access hatches and between them there is a livewell.I had to remove the livewell to get to the pumps bilge/livewell.In my case it`s a tight spot but can be done.When doing mine I also replaced the the links that attach the extension rods to the seacocks.
