Hi,<br /><br />I need to purchase a new aluminum prop for my Evinrude 150 HP V6. Which makes a better prop - Vortex or Michigan? Any recommendations on either?<br /><br />Also, do the props come with a new cotter pin, nut and thrust washer? Or, do these have to be purchased seperate? <br /><br />Lastly, is this a do-it-yourself job? I don't know much about engines, but the prop configuration looks pretty straight forward - thrust washer, prop, nut, then cotter pin. Or, is there something more to this?<br /><br />Thanks in advance.
