| Post subject: | Changed prop on LT now getting less rpms |
I've posted this on the LT forum: Had routin maintenance done and got a new prop on my 23 hp gdlt. Before, I could get above 3500 rpms in the water loaded, now I get 3300 max on the water w/ an empty load. I'm going to call sportsmans tomorrow and see what he says (where it was serviced) Any ideas, suggestions? |

couple of things could be happening with your prop 1. prop is not the actual pitch it is supposed to be, i purchased a 9x5 before and it actually was a 9x7 with really thick blades and had to have it reworked, so if you have a local prop shop they can check it for you. that would cause lower rpms 2. original prop was wore down so it did not measure 9 inches, that would also allow the motor to turn more rpms 3. and finally one has more cup in it than the other, again all 3 issues relate to your prop so that is where you need to start by having a prop shop measure it |

Where did you buy the prop from?? If your old 9x6 was worn let's say to 8.5 you will spin mo rpm!! I heard GoDevil repitched there props to help protect the motors..... I'd say run it |

You can only get 3300 RPM's empty, WOT? On my old LT, a new prop would drop the RPM's, but the speed stayed the same. Your old prop has a LOT of the cup worn off, and that makes a big difference. I don't know where you are located at in LA (I'm assuming your in LA since there is an LA plate on the trailer), but Go-Devil will recup that old prop for a small fee, and you would see how much of a difference it actually makes. |

a new prop will have more meat.. so, you will not turn it as fast. |

The Sportsman in Abbeville is a Huge Dealer of Go Devil.. I think the owner and Coco are bestest friends or something.. So, he would have for sure got it from Go Devil. |

I spoke w/ someone at a shop and he said that is accurate rpms to be getting. |

If I get it measured and it is a 9x6, would a 9x5 be a better prop? |
