2000 mercruiser m.4 mpi fuel pump and regulator

[B.matt]

Has anyone changed there fuel pump and regulator while still in the boat.? My throttle is limited to 3800 rmp. The cool fuel package is in there so tight I don't see how to get at it without engine removal.

Thanks

I'm guessing it COULD be done, but you'd need really skinny arms, that are double jointed all the way up.

Pulling the engine only takes a couple or 3 hours. And you get to check all the other things you can't see while it's in the boat.
