New noise

Dream_Inn

@YYZRC check alignment first and also gimbal bearings.

@YYZRC , how do your props look? I remember when I went on sea trial, I heard a noise that I wasn’t sure if it was the port gimbal bearing or the props. This season the noise is gone with the new Hill props.

YYZRC

Funny you mention props! One starboard prop was damaged and repaired prior to shipping the boat to me. Maybe it’s unbalanced.

If you can narrow down the side, swap the props and see if the sound follows. If you have the tools, you can remove the props in the water, not 100% as easy as swapping them on land though.

@aero3113 swap the props?? 1 is a left prop and the other is a right prop. Can't swap them the boat would go backwards............lol

Swap them from drive to drive, doesn’t matter.

Sorry bro but it matters. Port engine spins in one direction and S/B spins in the other direction.

I have to disagree on that. Both engines rotate the same direction. If it was inboards, different story. That’s why both engines have the same ID for Vissel View, and you have to change the ID. No difference.

When I received my new props, nothing was labeled LH or RH turn?

Motors turn in same direction, drives don’t. My 4 blade big cow props were left and right. 

YYZRC

Any recommendations on a prop wrench for the B3? OEM?

I definitely agree that our B2 drives rotate different directions.

aero3113

There is no difference between port and starboard props on a Bravo 3.

Aqua_Aura

On a B3 since they counter rotate then the probably are the same direction drives.

YYZ are you sure that it’s not just rpm out of sync? When rpm is out of sync you will have a totally normal waaaa waaa waaa and speed of the noise depends on how out of sync they are

@areo3113 I stand corrected. My mind was on a bravo 2 (that's what DI has). You are correct B3s are the same. Sorry for the confusion 

aero3113

No problem @raybo3 !!

I have the digital rpm on VV and they were within 25 rpm of each other. Is that enough of a difference to cause vibration and droning?

no, that is not enough difference to have that symptom.

yea agree with Dream if you are that close then thats not your noise

@YYZRC I bought the OEM this spring.  Heavy expensive thing but does the job.
