    1990 5.7. 260 Overcooling at idle.

    Mkos, I'm as puzzled as you are. The block gets cool water from the circulating pump when the TS opens. It opens which allows water to be pumped in and warmer water comes out around the TS. Only way for cool water to go into the block at out the TS housing is: The housing was not made...

    1990 5.7. 260 Overcooling at idle.

    My understanding is it was all 140 because of the main issue was salt water. When EFI and MPI came about they needed high temps so 160 came in. Merc recommended salt folks get close cooling. The service techs here can clarify like @achris @Fun Times @muc

    1990 5.7. 260 Overcooling at idle.

    You need the small hole in the Tstat so the air will bleed out. The one small hole doesn't have much effect on cooling Since it does have a 160 then I have no clue

    1990 5.7. 260 Overcooling at idle.

    Unless the thermostat was made incorrectly from the factory the senders should be separated from direct in coming cold water. Should be on the motor side Being in Erie just put a 160* in it, won't hurt even if you were in warmer waters

    2005 5.0 Me cruiser TKS Enrichment Module/Solenoid NO Power

    Good deal A shorted module can take the diode and fuse out. Having a new module you should be good. If fuse blows again then its the temp switch grounding out

    2005 5.0 Me cruiser TKS Enrichment Module/Solenoid NO Power

    The enrichment solenoid starts closing down once power is applied. When cold its open and provides more fuel to the motor until it heats up from power. If its not closing down then it may be bad. Power comes from the ignition switch and thru the diode to TKS. After about 10 minutes it should...

    Gimbal bearing.

    Do not quite understand your question due to (well re-read your statement) If you are installing a non-greaseable bearing where one which could be greased, it does not matter Before you replace it, feel it with your fingers. If its smooth, do not replace it. I sold my 1995 boat last month...
