So now that my boat is all fixed after replacing the starter - I took her out a few times this weekend. I didnt want to flush her until i knew how. I have earmuffs, and i can feel where the inlets are, but with outboards i usually put the muffs on in the direction of the bow to the stern.<br /><br />With a i/o, i cant reach the bottom of the motor to do this, so it looks like i have to put it on from the back to the front... but wont the metal peice holding the muffs together hit the prop when running?<br /><br />How long should i flush it for also?
