Mercruiser I/O vs Outboard SeaCraft?

[oldfielder]

One other thing I like about my i/o-something other people complain about, actually, is the engine compartment serves as a great casting platform in the stern. My buddy and I do a lot of casting and we both have our own region of the boat to work from-lot's of fun.
That mpi listed above must really improve performance over the carb-I'm not close to that speed with my 23 cc. I top aout at about 40mph. I suppose if I bucked up and removed the bottom paint I may pick up a few mph, but it's jsut such a nasty job that I don't want to tackle.
