W a supercharger the worst thing is detonation. The higher the octane the lesser the detonation.
Has anyone taken a stock 575 and added 9-10 pounds of boost? If so , What was the result? What HP did it make

There are a few Ron Potter-coverted engines out there making about 700. Tom A. on this board is a very satisfied customer. In stock condition, they are not the most trouble-free package as others have noted.
Keegan - My Volvo Penta's (540ci/600hp) sound just fine....

They make that kind of power stock, with chillers and 6 pounds of boost

What was your reason for going with the 600s? just curious. Guessing you went after the whipple upgrades and wanted more than 700hp?

i love my 575s. Send the blowers off to be safe and have checked at least, if not rebuilt. Change the head gaskets asap!
I would rather have a noisy blower, than have my boat sound like a volvo penta, but that is just me. I love the blower whine on mine.
They can handle 700hp all day if set up correctly. I was skeptical buying them, but now that mine are tuned correctly, they run like a full efi set up!
525s are great engines also. The 575s have more potential if you want more power out of them. Stock for stock i would go with the 525s.
