Hello,
I have an atomic 4 on my C&C 30. I have been sailing it for one year.
The motor works perfectly when it goes forward. The issue is when I need to go backward. It doesnt do anything, or almost anything. When there is no wind and no current, I can move really slowly, less than 1knot. So it doesnt take a lot to lose complete control of the boat!
By reading the manual, I thought that it might have been the reverse gear that needed some adjustment. But it didnt seem to be the problem. The shaft was turning quite fast in reverse, and accelerating when increasing RPM.
So I thought there was a problem with my propeller. When I got it out of the water for the winter, I did some tests and the propeller seemed to turn normally.
So the only thing that I think might be the issue is the type of propeller I have. I know the engine was replaced by an atomic 4 in the past, so could it be that I dot have the right propeller for the type of engine?
Here is the image of my propeller. It is about about 20 cm (8 inches) in diameter.

This is my first boat, and I even more newbie in the field of mechanics, so I might have missed important things to check in order to find the real problem. So if you have any idea of what could be the issue, I would be really happy to hear your advice!
Thanks a lot !
