Don't know what would be different on your boat, but mine does a 180 or 360 almost at the spot.
One in reverse and one forward, no steering input at all.
Formula 330ss B3, 7.4.

Fountain outdrives spin opposite direction of the formula drives and this make a difference for docking but adds to top end. I have owned both older formula and fountain and there is a big difference in docking but my 97 fountain better in my opinion at every other speed. I have not driven a fastec? Reverse prop direction counters the ability to spin props in different directions and turn the boat since pitch is working against it. Also if I reverse my engine farthest away from the pier it pushes me further away. Fountain spec sheet says 1997 with 500 hp/470 prop hps runs 75 mph at the factory quad 4 props. 70 mph with 415s so to get to 80 my guess 550 hp?If you test them let us know!

Not sure if that matters with a counter rotating prop drive like a Bravo III.

Pat Ousborne

Not sure either?

Just discovered both props, forward props spin to port and secondary rotate to starboard. Don't know if that makes a difference, got to check the props....

Seems weird, maybe Michael can say if his spin opposite of each other.

Or dare I say go to a cruiser forum,,,,,, lots of B 3's there.
