Doesnt look like it really falls off at all if you can believe chevys site...I would still prop for 6k. It makes an NA boat more fun to drive :drink::drink: |
I was very interested in buying this boat for a very long time. Seems like a lot of bang for the buck. Get the details worked out and you are gonna have one hell of a fast boat. Did the previous owner set the heads up for marine use?

Great information so far guy's, I really appreciate it. So at this point I should be checking my total timing, should it be 36 like Chevy recommends? And should I drop in prop pitch to get more rpm's? Is the X to low at even with the bottom, should I be going up?

I would definitely check the timing. Most people run the zz572 at 5400-5800 rpm.

36 degrees? Or is that to much for marine use?

The dyno test in the rag mag was 33° if that matters. Which it usually doesn't.LOL.
