    x7 vs LazerII

    Looking for advice on a couple different props. I have a 20 pitch Lazer on my boat now, been thinking about a Spitfire x7 in a 19 pitch. I dont want to lose any rpms as the LazerII is barley turning the rpms it should. If the x7 is stiffer it will be too much also. Looking to gain a couple hundred rpms . The boat is a 2013 Crestliner with a flashed 75 Mercury fourstroke turning about 5500 rpms with the LazerII. Have a bit of porpoise too and was thinking about adding cup to the LazerII but cant lose anymore rpms. Thinking the x7 may hold better and give me a few more rpms.

    The 20 laser II with three blades should turn about the same rpm's as the 19" X7 four blade. Has your laser II ever been worked to make it true to factory spec? Most of them need some work to run correctly and that can stop the porpoising but just adding cup will slow it down some.
