1800rpm on muffs

[reeldutch]

two weeks ago i replaced the tstats on a 1989<br />110 evi and everything seemed fine.<br />today i started it again because i will use the boat this week and it idled at 1800 rpm.<br />this is a litle high.<br />Normaly it would idle around 1400 1500 rpm on muffs. in water it did idle 700 rpm in gear.<br />dont know watr it is now.<br />i checked the throthle cable and trunion nut and i could not find a problem there.<br />could this have anything to do with the tstats?<br />the left side (looking from back) feels a litle colder than the right cylinder bank.<br />but it stil feels warm to me.<br />there were ssteel and i replaced with brass.<br />do they run cooler?

What comes to mind is with the new t-stats the motor could be running a little hotter which could kick up the rpm a bit. I have a pair of 1987s and I had a simular problem. Mine would not idle well at all and would die frequently when put in neutral. New t-stats solved the problem and brought the rpm up. Those motors don't like to run too cold or to hot.

Re: 1800rpm on muffs

so should i adjust the idle lower or check other things out before i make the adjustment?
