I have a 2004 Maxum 3100se with dual 5.0 MPI/Bravo 3 setup. I was thinking about moving up to a newer /bigger boat etc.. however My wife and I really like our boat and after further contemplation have realized we dont need a bigger boat so I am interested in repowering/upgrading the current set up anyone here with a similar setup upgrade 2x5.0mpi/bravos to 5.7 or even 383? also looking to upgrade controls to electronic throttle control. any feedback would be appreciated. thanks

Can’t speak to the controls but since they are mpi easiest way is to get two complete Mercury reman bobtail engines. If your 5.0s are in decent shape complete running mpi take outs that I see listed should fetch at least a couple (3?) grand each. I think the bravo 383s are about $11 k each. The merc remans come with a 3 year warranty I think. Not necessarily the cheapest route, but when was this hobby ever cheap.

I’m assuming the 5.0s are a little light on power in that rig?

You wouldn’t think you’d be lacking power with 520hp in a boat that size.
Pretty sure you won’t get fly by wire controls working with any GM mpi. Might be wrong.
