Boxes
What do they mean when they talk about boxes on an engine?
Or boxes in general and motors? What are boxes? |
We are talking about extension boxes. They are used to create a setback for the outdrive. The most common extension box for a B1 drive has a 12" setback, but 7" are very common as well. They can be had as straight or with lift. Usually the boxes with lift has a 3" lift. Latham, IMCO, Stellings and others are makers of extension boxes.

They fool the boat basically into thinking it's 12" longer changing the leverage point that the drive has and allowing the boat to run at less trim angle. In some instances like mine it actually raised the X dimension by 1" installing the Imco Neutral box. If you install anything other than a 7" Latham or 12" Imco Neutral or Stellings adjustablel box. Which basically leaves the Imco -3 box you have to raise your engine which in most instances creates ALOT of work.
