    Tachometer Problem

    You can try cycling the cylinder switch back and forth between cylinders, sometimes this will clean some corrosion off the contacts and it will work . may also look for corrosion at wiring points on back and at negative side of coil… other than that bad tach.

    Ive used the same for ring and pinion changes as well For exact swme rolling torque with no issues. I think Chris indicator is certainly a better and more accurate tool but can get salty for shade tree mechanic

    Mercruiser 3.0 base timing a myth?

    The instructions say to put the timing shunt in while it is running http://marineengines4less.com/images/companies/1/EST%20Ignition%20Instructions%20-%20ME4L.pdf?1431462059320 so i interpret this to mean start it with shunt disconnected from distributor then while engine is running connect it...

    Prop Fitment

    Thats an mc 1 drive. A prop for mc1, R,MR, and alpha drives will fit it. I believe The thrust washer need to be changed out to work with your current prop. it doesnt look like your new prop has a removable hub , its pressed in right?

    1990 5.7. 260 Overcooling at idle.

    I think You should be running the non restricted gaskets with your style thermostat housing ( cold manifolds). As AD said that isnt the issue thermostat should hold back water enough to keep it at temp. i would guess you have a mismatch between the thermostat, manifold crossover, thermostats...

    Confused with 5.7L Timing Cover Replacement

    You have a 96 and up vortec block, which is actually better… you can see 8 vertical intake bolts and the plastic cover plus electric fuel pump… just order parts for 96 and up the plastic cover is technically not reusable …

    1993 larson 4.3 coil
