    They are the same part, both are 160*F Merc may change a design or iin most cases, it changes vendors so the part number is changed to keep track of configuration. In any case you can use either and they both work the same

    That sounds like the Engine coolant Temp (ECT) sensor and or the Manifold Air Pressure. You may even have a MAPT (MAP with Temp). When cold the ECT should tell the ECM that its cold and give it more fuel, just like a choke on Carb. When cold the IAC should be allowing more air since there is...

    120 Mercruiser 2.5L - No spark

    I'm wanting you to verify that the points do open and close. This is the reason to loosen the dizzy, don't remove it. If the points do open and close then they will work. I want you to hot wire the coil just to find out it does run, disconnect jumper wire to turn it OFF. If it does run, now...

    2001 2960 with dual 5.0 GL PEFS Motors fuel issue
