I see Well a great prop but wrong size will still leave you flat, or worse, broken, you understand. Something is amiss, continue to be patient with our inquiries, and we'll get you sorted out and undo what has been mismanaged prior to it getting to you. A run of the mill 13x14 federal should still pull 3 footers on that boat so its not like you should need to experiment with an unproven recipe to get similarly good, solid performance. |

Somethings very odd with that prop. Besides the key, I wonder about the taper in the bore. |

Haha I hear they’re good props. I’ll be pulling skis and tubing, probably mostly cruising though |

Look on the end of your prop hub where the nut butts up against it, you might find the dimensions stamped right there.
Some have it on the other end too. |

Sounds good thanks. How about the acme 425? It’s a 13x13. All the 13x14 are no longer available for some reason |

Indeed, we advise against the 541 you are looking at!

451 that must be a case of inverse, modified dyslexia or something ![]() You better turn the key off and hide it somewhere till you get something like Gotta Ski mentioned as a starting point to keep the RPM's down |

Right I was looking at 541 prop, one on mine measures out to 11” and makes me cavitate past 6000 rpm |

That engine should spin a 13x14 5200rpm abouts or higher
You put a 451 on it it's going to frag the engine |

What's up with the stop collar?
And that's a LH prop, we determined that when you first arrived Should be 13x14 I see prop damage and wonder if the key is spun out |

Haha makes sense, how about a RH prop would that cause it? Print is hard to make out except for one code. Does this look like an RH prop? Also measures out to an 11” prop. https://drive.google.com/file/d/1W9mwUGi4wbtHeQJ1y5_0twl2P8nAhnDN/view?usp=drivesdk https://drive.google.com/file/d/1qej4GlOPJpcaY5bv8g_PW0Z87VTT5yb0/view?usp=drivesdk https://drive.google.com/file/d/1oYGUAEFVdVZuhp0gNQU1lbL0t7HPB-F-/view?usp=drivesdk |

It would be a lot easier to read what's stamped into the hub for diameter and pitch.
![]() You must have 4 thousand or so HP if it acts like you describe above, cavitating when you punch it at 30 |

I’m not sure I’ll have to take a measurement, but when I punch the throttle at 30 or so it cavitates. Out of the hole it doesn’t cavitate though, guessing whatever on there is wrong

In your case you need a LH prop with your 1 to 1 transmission that turns the same direction as the engine. Not exactly knowing what you're using the boat for, I'd say you might want to do a little more research before getting a 541 with your 400 ish HP 454 in the boat ![]() What's on it now as far as pitch and diameter? |

I’m looking at ordering an Acme prop for my 454, it’s a LH motor. Dumb question does this mean I order a LH prop? I was looking at getting the Acme 541
