Hi ,
I just purchased a 1997 z275 shabah 3 weeks ago. It has a 7.4 mag with a bravo 3. I replaced the plugs, wires, dist cap and rotor button. The boat works excellent and I just love it. I have owned a checkmate convincer and a few other power boats in the past but this mariah is my favorite.

I'm not sure of the prop pitch, it has the counter rotating 3 blades on each. It gets to plane really fast and easy, cruises at 22 mph @ 2800 rpm and tops out at 39 mph @ 4400 rpm, 2 people and half a tank of gas. I was just wondering if this is normal? It seems a bit slow to me? If this isn't normal does anyone have any suggestions on what I should do?

Thanks,
Bill

Failed to also mention, you probably have a 2:1 outdrive and 24p props. If so, thats exactly how fast it should go.
