Hello
03 066 225. In gear at idle speed hear vibration noise. Sounds like it is coming from lower unit. Has 3 blade prop on it. Noise goes away with just a little throttle. We put 4 blade prop on it and noise went away. Dealer says it is a harmonic noise?? Why did it just start ? Started after water pump was changed. Any ideas
Thanks
This is probably when you're running the motor out of the water right? I have been told this is just due to play in the impeller within the housing. Depending on how tight the collar is pushed down on the shim and wave washer that rides on top of the impeller within the pump housing. I've had motors that do it and others that don't. It doesn't seem to be a problem with pump performance or durability.
Items #28 & 29 as well as #27 seem to be responsible for the vibration noise....

does not do it in neutral. I told dealer that it did not do it before waterpump was replace but they said it had nothing to do with noise
Thanks
