Noisy Evinrude 115

[Andrew Leigh]

Hi,<br /><br />on the water this weekend and noticed an engine noise. Not too sure if I have heard it before as I take my boat out about once every 2 months weeks and one is inclined to forget the characterictic sound of ones own engine.<br /><br />The noise is a mechanical type buzz that can be best described as "a light fast noisy tappet" as found in a car.<br /><br />The noise starts at +- 3500 rpm and dissappears at +- 4800rpm. WOT for me is 5000rpm with four medium to large sized adults. This means I have to be at full throttle to get rid of the noise.<br /><br />Cheers<br />Andrew

Check your hood latches as you may be encountering a harmonic viberation type noise due to a slightly loose latch.

Hi Joe,<br /><br />thanks, the harmonic "sympathy" vibration sound like it clould be it as at a much lower rpm there is also a hint of the noise.<br /><br />Whilst on the water I did not want to remove the hood whilst the engine was running, dangerous with that flywheel ripping around and unsteady footing. Will set it up with the muffs.<br /><br />Cheers<br />Andrew

hello<br /> dont attempt it on the muffs. next time your cruising and the noise is noising just go back and place your hands on the latches.<br /> if the noise quits you found it.make sure the water is calm though and a trusted driver is at the helm .the front decal plate on my 85 120 rattles and makes a buzzing noise about 3500 , if I was not so lazy I would remove it or Glue it but its done it for 10 years now so I dont even hear it.<br /> good luck and keep posting
