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? |
