We have a 2012 250 verado on a 25' tritoon southbay. Runs great with a 19 pitch merc prop. Turnd 56 hundred rpms. at 51 mph. Looking for a 4 blade prop. It should turn what rpms at wot?? I was thinking about b blades? Has anyone tryed them on a tritoon? The boat has strakes. Looking for more midrange. Thanks for Your help. Artie

First off. What do you mean by this? "I was thinking about b blades? Has anyone tryed them on a tritoon?". There is no such thing as a Bblades prop, other than the Blaster, and that is not what you are looking for. Bblades does have a test program and can sell you the prop suggested below.

If you are spinning 5600 rpms, you are quite over propped. Your motor is supposed to spin 5800-6400 rpms. For a 4 blade, I would try a 17" Revolution4. With your slip of about 7%-8% at the moment, and partially depending on which Merc prop you've got now, it should put you around 6000-6100. That should work quite well for mid range efficiency. A 17" Mirage+ could also be a good choice, even though it's a 3 blade. Which Merc prop are you currently running?
