Mini Jet Boat Ep.1: The Beginning

We have an old, crusty Allison 250 C-18 turboshaft engine, originally used in a Bell Jet Ranger helicopter.
We need to clean it up and get it into running shape, so it can put its 317 Hp into the jet water jet drive of a very small speed boat.
Let's take a quick look at the engine and what needs to be done.

The specs for the C18 are listed on the Wiki page here: https://en.wikipedia.org/wiki/Allison_Model_250

Although the pictures are of the C20, which is very similar.

To see a Bell Jet Ranger being used as an aerial tow truck, have a look at my video about racing on the Dart River in NZ. Heli footage starts at about 15:00.
