I am getting what seems to be knocking at low rpm. It happens when I engage my transmission and let it idle engaged. The tach is reading around 800 rpm. When I give it more throttle it goes away and seems to run good.

Could this be a timing problem?

The engine is a Indmar 350. Carb version, 310 HP.

What octane do you use?
