Re: yamaha flush
Hi,<br /><br />I have a 2003 F50 4 stroke and finally I have resolved the frustrating issue of flushing the motor with ear muffs.<br /><br />Firstly, increase water pressure will help. So I modify the standard ear muff. The standard ear muff has only one side feeding water. So I bought a second pair and put together a new ear muffs that have water feeding on both sides. A 3 way coupling would help.<br /><br />Secondly, make sure that the ear muffs not just cover the black square water intake but also the little hole off the top left hand corner of the water intake. If you don't, water will come out of that little hole - reduced pressure.<br /><br />my 2 cents worth and let's know how you go.<br /><br />Cheers, Breamo
