557 HP outboard from Seven Marine any good?

[Rotary John]

Seems to me the Homelite/Fricer Price 4 cycle outboard was a car engine set on end also.

Dont know how how Bruce handled oil delivery thankin dry sump

Hey guys, The "557" is a horizontal crank all-aluminum BBC with wet sump. Go to the website and look up specs. Complex and powerful, quick change. Got to be the most powerful "production" outboard ever built.

Needs a Low water pick-up , surfacing prop and jack it to the sky.

that thing is insane

[Powerabout]

Steering done right ( OMC patented this years ago)
twin pinion lower to take the grunt

Wonder if they used anybodys bolt pattern on the lower???

Actually, it's a modern GM small block, not a big block Chevy:"The 6.2-liter V8 outboard features an all-aluminum, supercharged powerhead sourced from GM Powertrain that is the same engine used in the Cadillac CTS-V automobile."

But at $70, 000 each, I'd prefer a good Crusader/ Volvo outdrive.

How much is a 525efi Merc ?

[Fastjeff57]

496 MAG H. O. and Bravo III $29,525

That's for a standard big block and Bravo III drive. The really hot motors and drives are probably twice that amount.
