Greetings,<br /><br />I have a alpha one I/O and I need to change the impellar. How difficult is it? I'm very mechanically inclined with cars. But I'm kinda new to the boat thing. I just want to know if this is something that I can tackle or Should I pay my boat dealer 200 bucks for a 25 dollar impellar. <br /><br />PS I have an awsome set of tools<br /><br />Dan
