Timing / drone noise

I think I just found the source of my drone / port motor running like a paint shaker!!!! What do you think of this weird thing??

Before I tell you let me say that I bought the engines/boat like this, I never touched this part of the engine.

So, I removed both the port and starboard black timing belt covers from the twin 1997 Honda BF90 outboards. I rotated the starter gears until the "T" on the gear lined up with the "T" on the black plastic on both motors. Then I looked at the cam gear on the Port motor and the arrow lined up with the #4!!!!!!! The Starboard engine's cam gear lined up with the "T".

My timing is 180 degrees off !!??

I have an extra cam gear that the timing belt goes around and there is a pin in it so it's keyed. This means it's not just put on wrong, it's really rotated to the wrong position.

What do you think?
 
Rotate the starter gear another 360 degrees. The cam will probably end up on #1.

#1 and #4 fire at the same time.
