Anyone know how far apart the motor mounts are on a 350 and a 454?

This is for a 5.7 should be the same as the 350 http://wwwarchive.mercurymarine.com/upl ... 864759.pdf

Thanks. The reason I asked is because I set my motor stringers for a 350, and now I might use a 454. Just wanted to make sure it would work. Thanks again.

Doesn't matter if it a 350, 454, Cummins 6BT, or a Detroit diesel. Install the standard width inboard stringers and you can choose whatever engine you wish.

If you space the stringers so that you have about 26" between them ( Inside of stringer to inside of stringer), you should be fine for either the 350 or 454. You will then bolt/epoxy motor bed timbers, three or four inches wide, to the stringers for the motor mounts to actually sit on. You can find many pictures of this setup on the forum....Hope this helps....Neel

Thanks guys. I spaced them at 26" but wasn't sure if a big block would fit between.
