I doubt you'd see any dramatic difference. A new carb will probably run
better over all but it won't be night and day. The aluminum intake will
take about 20lb off your tail end.

Have you moved the battery(s) to the front? Try to stow only light weight
items in the aft compartments.

Plus some other odds and end including a couple digital cameras cheap

I have a '77 marquis small cuddie. 23 ft. with a box stock mercruiser
350 chevy 4bbl. It runs very well, but the boat is heavy and it takes
it a bit to get it up on plane, but once leveled out the engine
handles the boat really well.

Quesiton is, with the set up you are offering, what type of
performance/economy difference can I expect?

I know. YMMV.
