Hi all,
I have a 2007 Mariner 30hp 2stroke outboard, i'm having trouble and have had this problem since new, flushing out the motor using earmuffs. You have to keep fiddling around with the position of the muffs and then they work (tell tale i mean) If i put the motor in a drum it picks up no probs. I have heard that you can use muffs with a double connection or are there a particular brand of ear muffs that are good. (the muffs i have are the ones that came with the boat ie cheap) Are there any Mariner / Merc owners out there that have had a similar problem and how did you fix it.
Cheers Fozzy.
