How does the Turbo Fusion 4 compare to the Merc Rev 4?
The Turbo comes in larger pitch sizes.

Re: Bravo-1 vs. Revolution-4 (Labbed vs. Stock)
Just an FYI:
Got a chance to test a 23" Rev-4 on my Baja 232 this week. Although I have tested with both a 23" Mirage/PLUS and a 22" Bravo/1 reaching a max speed of 66-67mph, both running as smooth as silk in 1' wind chop.
The Rev-4 was quite different. Running offshore in 2' seas, the Rev-4 performed pretty well but seemed a bit "loose" all morning, not terrible, but not a solid, hooked-up feel like the Bravo/1. When I made my first high-speed pass behind the breakwater, at about 60mph I began to experience a somewhat violent chine walk which seemed to intensify as the speed increased. It became a bit scary so I throttled back at about 64mph and didn't loose the chine walk until I slowed to about 40-45mph.
I have never experienced chine walking before on this boat and the only thing which was different was the new Rev-4 prop I was testing. I am assuming this prop has some design characteristics which may have been the cause?

Pat,
We have seen the Fusion 4 run similar to the Rev 4. The Rev 4 is typically 1-2 mph faster. However, the F4 comes in pitches to 32! And, the higher pitches, are higher in rake angles.

Re: Bravo-1 vs. Revolution-4 (Labbed vs. Stock)
pat's got it...
at least from my experience....my revo4's work exceptionally well on my "old school" 87 sutphen rumrunner, twin 350mags
42mph at 3000rpm, 54@3800, tabs down a bit past parallel, drives out just a bit above parallel..the mid range handling and cruise are awesome...

Re: Bravo-1 vs. Revolution-4 (Labbed vs. Stock)
FYI ..... I'm interested in selling my 23p Rev-4.
Bought new-in-the-box for testing, it's a 23" pitch RH 4-blade Mercury SS propeller (48-857030-A46) which has been used for less than an hour and is in absolutely MINT condition with no dings, scratches or nicks. $275
PM if interested.
