Hi,<br /><br />I've got a 1987 Evinrude outboard 8hp motor. I cleaned out all of the water paassages manually and still had to take it to a mechanic to get under the powerhead. All he did was push a wire ina and out and I don't think it is as good as it should be. <br /><br />I've seen liquid cleaners sold at Florida Sportsmans seminars and was wondering if they work?<br /><br />This motor has been used in salt water for 15 years, and even though we flushed it out it still got plugged up with sand and salt. <br /><br />I've tried limeaway and things like that which didn't work well.<br /><br />Thanks.
