warning horn

[Throbbin Rods]

I have a 1989 150HP Yamaha that starts and runs just fine. If I idel out away from a launch and leave it idling while the kids te skis/tubes/kneeboards ready, I get a constant warning horn. If I gas it and run her a little faster I have noe problem. New fuel lines, new inpeller, new spark plugs. Any thoughts will be greatly appreciated.<br />thanks<br /><br /><br />Throbbin Rods

Re: warning horn

remove the pressure relief valve cover, remove the grommet, clean the pocket area with a pick and install a new grommet.
