Priced for quick sale an Outboard Jet Drive that fits several Yamaha 20" shaft outboards.
It will bolt right up to all of the two stroke V4 105.5 Cu. In. which range from 100Hp to 140Hp and it came off a 115/80Hp model. It will also fit all of the two stroke V6 158.4 Cu. In. which range from 150Hp to 225Hp. The V6 models should have the impeller swapped out with a higher pitch one because of the additional horsepower. This unit will also fit the Yamaha 115Hp Four stroke in line 4 made from 2000 to current but will need the drive shaft swapped out.
This Jet Drive is the "AA" model and comes with an adapter plate and stainless mounting hardware. The shifter cable is not included because your application (tiller or boat control) will dictate this part number. This unit has very light usage and also has a new impeller. The manufacture of this jet drive has several downloadable pdf's and you can find lots of information there, be sure you remember the "AA" part number listed under the large jet drive category.
