Here is the whole embarrassing story. A friend was at the helm, we
were motoring down the channel at 2600 RPM. I have a 3 cylinder Yanmar
engine. I was dealing with the sheets. I asked my friend to slow down.
He got confused between the transmission and the throttle. Instead of
cutting back the throttle, he threw the transmission from forward to
reverse! There was a terrible noise as you can imagine. My friend
immediately realized that he had made a mistake and shifted to
neutral. After that, the engine and transmission seemed to behave
normally but now I am not as confident as I was. So what do you think?

I think if there were a problem, there are a couple easy
ways to find out.


Will I need a new transmission? And what about the folding prop? Any
advice would be greatly appreciated.

Should be OK, drain the fluid and look for metal in the fluid.


Don't have to drain it, just pull out the dipstick and stick
a magnet down there. Or send a sample to an analysis shop (a
good idea in any event).

Good argument for a proper throttle.


What's "proper"?

2 other things come to mind... operating temp (I bet you
don't know what the operating temp was before) and the
linkage. At least the linkage can be carefully inspected &
replaced if need be.
