like get a chevy!!!!..hahaha
cut that impeller down, and you'll get some more rpm, but, it doesn't sound like you have much power there. 400 should get you around 4800 or so. i'd build some more motor over the winter. put a aggressor nozzle on it. they make a sweet adjustable nozzle. talk to pops1, or call em.
What are the particulars of this 460 Ford? As SDB said, sounds like your down on power, and no a BBC isn't the only road to a faster boat. Even a stock 330 hp 460 marine in good tune should pull more than 4000 rpm with an A impellor. I'd go over the engine and tuning to see why its not healthier, check compression, spark advance (initial and more imortantly full advance), ignition system, carb linkage at WOT, jetting, etc. Also on the 460's, many post '71 engines came with 8 degree retarded cam gears (makes for a lazy engine), this can be remedied by using a pre '72 crank gear or a new 3 position timing chain set.(Edelbrock, Comp, etc.).
is the ignition getting full advance? are the secondaries on the carb opening all the way up?
Pioneer's are Cool

hey i had a similar problem with my boat same motor and it took a few months for me to finally find that i had a valvetrain problem (wewak springs) my motor sat for about 3 years and the springs on some of the cylinders were weak.
but check all the normal things like spark fuel compression
