No issues, and love the motor. However, I am going to put a new impeller in it (as a preventative measure), and haven't done one before, as my old boat mechanic guy has passed. I consider myself "mechanically inclined", but also humble enough to take advice or tricks before I start! ANY VERBAL TRICKS OR HINTS? I know that boat motors are a different breed than other vehicles, and that always makes me a little skiddish....
