That is not a block casting number. Not sure what that number is from.
Post what you know about the engine that you have.

Are you near Spokane? If so it wouldn’t cost anything to have Mark or Chad at Legend Performance Marine to take a quick look at it and tell you what you have.

I thought that the number he has is from the Mercury tag? I used a zero for the first number which he doesn't show. 0F774641. I used that on one of the sites and it came up with the description above.
