The K-5-B cylinder was designed for inboard/outboard boats requiring external cylinders of substantial size and strength. The K-5 cylinders are nickel plated for aesthetics and protection against the elements. This cylinder does not include the wing plates or hardware required for mounting to the outdrive. Porting is through two through-transom 1/4? NPT ports located at the mounting end of the cylinder. Notice K-5-B steering cylinders have a large volume. To keep total wheel turns at a reasonable amount, it is recommended to use a larger displacement helm pump, such as Capilano HH5275 (5.4 cu.in. displacement MAX).
