Hey Guys,<br /> maybe someone can help me. due to the war on terrorism my boats been sitting for a few yrs.<br /> I now have it cleaned and ready to go, my mechanic tuned my 1986 mercury i/o 140 up and it kind of runs good. Heres my problem, my temperature gauge red lines. my cooling system is running well because i have the ears attached and i can see the water being exhausted out of the lower unit, but the gauge red line. I opened the thermostat housing and noticed rust particles in between the sping of the thermostat I suspect that the rust particles are preventing the thermostat from functioning properly. I would appriciate any advice that helps clean out the cooling system of the rust particles.
