Got a stethoscope and it seems to be coming from the rear of the engine, where the bell housing meets the drive. It’s a metallic sort of noise - bad gimbal or something? Doesn’t sound like it’s coming from the engine itself though…
Thanks Rick - cant pull the drive as the boat is in the water, and i dont have anywhere on land to work on it... Is this to isolate if the noise is coming from the engine or in the drive?
Hello! I have owned a 19 ft runabout for the past year and in the past few weeks there has been a knocking/rattling noise that has gotten worse and worse. It is noticible at idle, and is deafening at any RPMs above idle (see attached videos for idle & about 2500 RPMs).
The boat was recently in...
