    Prop Repair - Vibration

    I had two props repaired at the same shop that has the Acme blocks. One works fine, the other prop vibrates between 3200 - 3800 rpm. I took the prop back and he balanced it. However, I am still having the same problem. He showed me how the blades line up on the Acme blocks and that the prop is balanced. He said that he has done all he could do. I might have to buy a new prop. Any ideas?

    Was the prop static or dynamic balanced?

      I don't the name of the way he balanced it. But, what he did was balance it between two even bars and took off material if the prop rolled one way or the other. So, I am guessing "static"

        I had the same experience with a prop that was repaired once. It never was 100% smooth after that. Guys who insist that repaired props always come out OK are not speaking the truth, IMO. It was not badly dinged either.

        That balancing process does not sound all that reliable to me. These boats are terribly sensitive to balancing. If both blades weigh the same, but the weight is more centered towards the center of one side and the periphery of the other, you will still have vibration once the prop is spinning.
        Be excellent to one another.

          Wind caught me this weekend and I dinged the new 1235 on the trailer...that's what I get for being in a hurry and not using the "guides" like they were meant for. Good thing we won one at the TO Reunion last year. I'll get this one repaired and keep it as a spare. Lesson learned!!

            I always send my prop back to Acme.
            Tige, it's a way of life!

              How much did you pay him? Fact is, his repair didn't work! You shouldn't have to pay. If he doesn't believe you, make him on your boat with you. After all is said and done, demand that he send it back to Acme. It will cost you roughly $150... but better than the $250 of a new prop.
              Being a major OU fan and a staunch conservative.... I am perpetually vexed w/ the conundrum of who to hate more. Obama or the Univ. of Saxet.

                If you know of a new prop for $250, you better buy it right now!

                  LOL... I started thinking that was wrong after I typed it. What are they now? $500. It's been a while since I bought one, but for some reason $350 is sticking in my head.

                  Either way, it's still better than the $5-$10K that some of the offshore guys spend on props!!!! Yes I typed that right! $5,000-$10,000

                    Well I bought that never quite 100% repaired prop from Tall for a good price about 5 years ago. It was only a back up to take to Powell just in case I dinged mine- that way the week wouldn't be lost. The next 4 years I never had to put it on or use it, but I was prepared. So I sold the Tige to my houseboat partner and two weeks ago as he was getting ready to go to Powell, I loaned that prop and a puller kit to him. Of course on the third day there he hits a rock and discovers that he left the loaner at home by mistake. So the next 4 days they only had jet skis and no boat.

                    Two things to be learned,
                    1. You won't need the spare unless you forget it.
                    2. Those not quite 100% props are a cheap back-up to keep from spoiling a vacation.

                    And sometimes the vibration is only at certain speeds or rpms.
