    Starting Issue - Twin 1988 Merc 4.3's

    Hi Nola Mike, I'm pretty sure that was with key in START. I had Port running and went to start Starboard, cranked it and watched Port die. I changed out both starters and the slave starter solenoid for Starboard only but that was before I put her in the water in November for the test run - both...

    Two batteries, one electrical system. I can start either engine with either battery.

    Engine siezed

    If they pulled the motor, did they not drain the exhaust system??? How hard is it to pull some drain plugs and then winterize the motor until ready for re-install??? They sound like idiots and you should not do business with them if possible. I would pull the plugs and spray lots of penetrating...

    I should correct my original post - I think I have the 1989 motors, not 1988. I say this because the Merc manual shows my style of ignition amplifier (sort of pyramid shaped mounting bracket) on the "1989 Models - On" schematic.

    I checked all grounding when I had my starter issues earlier last year - all good from what I was able to tell/measure with ohm meter. Will check the key switches for corrosion - that seems possible.

    Let me first thank @San_Diego_SeaRay for the help he provided on my previous issue with my 1989 Formula 26PC - starting issues due to bad/corroded starters and slave solenoids. Previous post here: https://forums.iboats.com/threads/starting-issue-after-unrelated-mech-repairs.758138/ I finally...

    Starting Issue After Unrelated Mech Repairs

    Ok, I've ordered two new PMGR upgrade starters from Sierra, hopefully a little smaller and lighter than the originals to help go back in easier. One question: the two long bolts that hold the starter in are perpendicular to the axis of the motor and do not really clamp that mating face to the...

    Ted, Re the slave solenoids: I do get proper voltage down at the starters themselves (on the yellow/red exciter wire), downstream of the solenoids so they are making good contact when the key is turned to START. Should be good there, yes? That starboard voltage gauge seems fussy - it pegs (16v...

    Difficult to get to w/o taking the starters off, especially starboard where it's all but impossible. But they all looked spotless from what I could tell.

    Yup, that about covers it. Can't think of anything else other than the starters themselves. Was hoping it was something easier to save myself having to squeeze into that tiny bilge but that's life :)

    Starting Issue After Unrelated Mech Repairs

    Ok, here are my latest results after buying some long test clips as you show above: 1. I confirmed 12v supply via the thick red wires to each starter. 2. Since I already established that the slave solenoids were 'clicking', I checked and confirmed both solenoids output 12v output all the way...

    Good tips, thanks for clarifying what is essential and what isn't. Might be a little tricky getting jumper cables into that tight spot at the starter but will try. Should be able to find some long test leads w/ alligator clips at work and test them out Friday or some time this weekend. Thanks!

    Thanks, I'll check it out. Also ran across the one in the Merc manual last night.

    Hmm, scratch that about the water temperature switch - was just looking at the Merc manual and the testing procedure for the Audio Warning System Buzzer is to 1) Turn key to ON position, 2) Wait 7-14 seconds for horn to sound. Guess I installed the right sensor switch and did it correctly :-)

    Starting Issue After Unrelated Mech Repairs

    Ok, did some more troubleshooting - here are the long winded results: 1. Checked resistance from both starter housings to their respective blocks: both 0.4 ohms, so good contact between starters and ground. 2. Checked resistance from BOTH blocks to BOTH negative terminals that get bolted to...

    Got it - another useful trick. I have a meter and will check it out in the next day or two. Any thoughts on the edit to my original post? I have separate voltage gauges for each motor/battery/system. The port measures 12v when I turn the key to ON, but the starboard pegs to max. Seems very odd -...

    I went to try this yesterday and it didn't seem to make any difference but on the way home I realized I wasn't thinking - I have two motors, two batteries and what appear to me to be two different electrical systems, and I didn't think to check and make sure I was connected to the battery that...

    Took a look at the connections on both both starters - I thought I would find at least some corrosion but everything looks clean/nice. Didn't see any obvious corrosion on any wires or connections all the way to the battery. The starters themselves do have corrosion on their lower surfaces, a...

    Well, last time I started the boat was 2 years ago so... Yes, likely corrosion so will have to find a way to squeeze myself down in that space... ugh.
