Blower boost,Merc 600 SCi
 

New owner wanted to know,can't find it on Merc website. I know it's pretty low,but don't remember.

If it has Smart Craft you can toggle through the pages to find it. Its under manifold pressure, I think. 4 lbs, sticks in my mind, but not sure. We had them in a 38 Fountain. Im sure Dustin Whipple knows. I know when you hit the rev-limiter, a message comes on the smartcraft screen saying it was reducing power. I guess by a boost bypass.

4.5psi at peak, during sea level or near sea level applications. Overspeed is handled by misfiring cylinders vs. boost. Rev limit is nice and soft.

4.5 psi boost.

620 - 635 crankshaft hp and around 820 Nm torque, seems to be what the stock motor delivers.
The power peaks at around 5100 - 5200 rpm, so propping to run to the (5350 rpm) limiter doesn't usually produce the best top speed.

4 lbs. was about all you would see on the gauges at LOTO.

At w.o.t. 5400 rpm I have seen between 4-5 max on boost guage

Power does not peak at 5100rpm, it continues to climb. Stock rev limit is 5400rpm and that is peak power in stock trim.

Has anyone been to the Merc Racing website lately? The new fuel spec for the 600 is now 87,down from 91.

Yes, I did catch that, that was one new "update" but the 700 will not follow.
