    1995 5.7 Mercruiser no start, no fire.

    Nice. How'd you find it?

    Heat Exchanger blocked: recommendations how to flush or unclog?

    He said he's got a 170, which is the 1985/86 3.7l. paired with an a1g1 and full OEM closed cooling. Only pump is in the drive, as mentioned.

    Mercruiser 170 - Spark at distributor, not plugs

    Spark plug/coil wire, plugs, cap, rotor are the only possible failure points. If you're not getting spark at any plug, I'd guess that the issue is at the rotor button connecting to the cap (I read this as having spark off the coil wire)

    2010 4.3L TKS Thunderbolt Ignition Troubleshooting

    The Sierra ones are good, and I've seen a couple of other decent ones. Good ones have a plastic coated inner sheath, pretty obvious if it's quality or not. Electronics, who knows, rubber who knows.

    Alignment question chasing the marks or slide the tool

    The whole point of the tool is to make sure that there isn't stress on the coupler. If it slides easily, you've confirmed that you're not stressing the coupler. I think the witness marks are secondary, to be used to figure out how to move the engine when the tool won't move freely

    Op confirmed that he's having a spark issue. Can't think of a tks failure that would do that...

    2010 4.3L TKS Thunderbolt Ignition Troubleshooting

    As mentioned, if your spark test at the coil is consistently good, the failure can only be in the ignition sensor or in the cap/rotor/wires, or wiring to the sensor. If it's intermittent, then all bets off. Edit: Also, wouldn't expect an intermittent issue with the sensor itself unless it's the...

    2010 4.3L TKS Thunderbolt Ignition Troubleshooting

    Glad it's working but I don't think that's your problem. If either the tach or SIS is grounded you won't get spark from the coil during the TB troubleshooting test.

    2010 4.3L TKS Thunderbolt Ignition Troubleshooting

    Might also try that last test on the plug wires (or at least 1 with the rotor lined up). Your problem could be coming from the rotor/cap/plug wires as well as the sensor (which it still sounds like)

    Early EZ Shift outdrive questions

    I think real old drives had a different number of splines in addition to a different length drive shaft. Shouldn't be an issue if swapping the shafts though. I did think that the cutouts were different sizes for some reason. And also, was OP hoping to keep inner transom plate or swap the whole...

    Exhaust flapper fell down in the exhaust tube

    Flappers can supposedly wear a hole in the y pipe over time, though I'm not sure if it's the flapper itself or the pin that does the damage. Good ideas about trying to reach it from the drive side

    Good point, wrong plugs if so. Ya think that would cause them to blow out like that?

    Mercruiser Shift Issues

    Glad it's working, although that doesn't make a whole lot of sense. If you made that switch easier to trip, and it's still hard to shift by hand that would make the problem worse. Either way, pressure testing the drive and fixing the leak is an easy way to potentially keep you from having to...

    Alternator issue 4.3 Mercruizer

    It doesn't sound like your alternator was working correctly at all this year. It should be putting out closer to 14 volts. If anything, you need to be worried about the battery with the tender attached, although I doubt the amps are high enough to do any damage. Yes, battery connected backwards...

    Transducer mounting options?

    Well, they would tilt, but the ones I've seen still have part of the mount below the hull. that plate is just PVC--not sure why that didn't immediately come to mind, thanks. I have pvc trim pieces lying around that should work. Still going to think of a good hinge design
