idle setting in lake?

[miniblind]

my 7.5 merc 79-80, starts and runs good in a barrel. When in the lake it is hard to start and keep running. I learned from an earlier post that this is due to the idle setting that must be set in the water.<br /><br />Is there a way I can get the setting close so when i get to the water it will at least stay running long enough to adjust the idle?<br /><br />What way do i need to turn the screw?<br /><br />Thanks

Re: idle setting in lake?

Your manual should tell you what setting is best. What I did is ran the idle screw all the way in then backed it out one full turn. After that I adjusted it in the water. Remember to turn it in small increments then wait 10 seconds before adjusting again.
