Finally got a chance to run a new stilleto advantage 2 on my 221 and thought it ran great and Ive run everything just about on this boat prop wise , problem is the prop came with a pressed in hub for a Volvo or omc and was able to rig it up with a combination of thrust washers for a brief run I am looking for one with a interchangeable hub system or pressed in hub for a Merc or any recommended prop with similar performance
