Last year I replaced the stock 180 hp 4.3 in my 1996 20 ft Mirage with a Merc 320 hp 6.2 MAG MPI. I run a 21" Highfive on a 1.47 ratio Alpha Gen II.
Great swap and completely woke the boat up. WOT went from about 47 mph to just over 60 mph, but the hole shot and pulling is where you really notice the extra hp. Plus it just sounds a whole lot better, since I installed hardin side exhaust outlets. Only trouble is my neighbours don't seem to like me much anymore!
I have noticed that the hull gets a little squirrelly at top end. Plus the only time you can really let her rip is when the water is fairly calm, and how often does that happen?
I have not noticed any higher fuel consumption overall, since we do a mix of towing and cruising. The EFI is a huge improvement over the carb.
That's why I thought 59 mph with 220 hp 5L sounds too good to be true, unless the boat only weighs 1800 lbs or so.
