F150 noise level change

[ccm14]

Hi,
I have a 2006 Yamaha F150 that has always been unbelievably quite when at idle and when running. My last trip out I noticed the motor was louder than usual. Not that it was loud but just not as quite. The motor only has about 55 hours on it and is serviced regularly. The motor is used about 50/50 in salt and fresh water. My last trip, where the motor made more noise, was in salt water.

Anyone ever experienced this situation and was there any problem that needed to be addressed?

Thanks for taking time to offer your advice.

Charlie

Re: F150 noise level change

If it's making a whine that increases with engine speed,it's the counter balancer located on the front of the engine.it's alot easier to hear with the cover off. While not actually a recall,yamaha replaced them for free.Check with a good dealer and see if they will help.

If it's just a general increase in noise but no 'new' noises, check the gasket around bellypan for even slight gaps or cuts....a very small crack will let out a surprising amount of noise....saltwater has nothing to do with it. Great motor.
