Post PD Engine whines at 3/4 throttle
I just got a new prop for my 36 pd, I noticed that at 3/4 throttle the engine whines.

Any ideas? I just noticed that my case gasket has started to leak a small amount, I plan on taking care of that in february.

should I be concerned with the engine sound?

prop is new and still has the black paint on it.

I took her out again today and was leaning back while driving and it sounds like the noise is coming from the area around the muffler. fMy muffler is just over a year old and since I run alot of saltwater, its in pretty bad shape. Could it be the baffles in the muffer?
