    Shift control replacement

    What did you do? I'm in the same boat, outboard control box bought in error and installed only to find out the wires don't tie out. Trim works, but boat won't start just turns over

    Ok I "borrowed" a digital dwell meter for $68 on Amazon (one of my biggest fears is that when I die my wife sells all my sh17 for what I told her I paid for it... :) ) The dwell range on this engine is 28-34 as is noted on the valve cover spec sticker. At the first test it tested at 44 which has...

    No sir. I tried to find a loner but most of my gear head friends have moved to warmer climates.

    Hey all! One of the things I've noticed while trying to research a solution to my boat issues is that posts just abruptly end. Which I get, we are all busy but it'd be nice to see how a solution actually played out. In my case this was an engine swap of a 1987 2.5 for a 1986 3.0 EVERY SERVICE...

    Continuing to trace my no start condition. This is a two parter. The first part is from my continuity testing of the engine side of the wiring harness: Should both yellow and purple/red wire show continuity on the black #1 wire harness socket ? as well as both posts of the coil to black #1 and...

    For sure. The reversed wired alternator theory failed this AM

    One of the other things I replaced on this is the alternator. I swapped out the one that it came with because the the wires that were "imbedded" in it were corroded. I replaced it with another, made for mercruiser, alternator I had laying around, but made a few what I felt were logical...

    What if there is no spark? Where would go from there ?

    Yes sir. I did that with the old one and the new one I just installed to be sure. The old one was fine too, but I used the new one since it came with the kit.

    Filed and no reading on digital voltmeter I don't have an actual dwell meter. It's acting like there is a kill switch but there is none. Everything is grounded all connections tight, battery is fully charged, I'm shot.

    I gapped to .22 but I did not check the dwell angle for degrees. I've never done that it just always worked. I'll try that tomorrow. Thank you

    Skunked again. Tomorrow I will work back from the ignition at the helm and work my way back. Maybe I'm looking at this all wrong. I did have this engine running in my garage out of the boat by jumping the #5 & #6 female (engine side)pins in the harness connector and adding a hot wire to the +...

    Happy Friday All, based on all your feedback I'll be installing these this afternoon as the no cost purple resistor wire fix didn't work for me. What the heck it's only money and time, and I'm a moron for owning boats..... no I'm not I love this who am I kidding :)

    These are new points, wires, and distributor cap. Two beers 5 minutes :) Do you know if the terminal on the stater solenoid should be kicking out at least 12V ? Mine is only kicking out mid-high single digits, everything before that point is over 12. Even if it were the points would it affect...

    Sorry for the lack of an update, we got drenched here in this neck of the woods yesterday. Unfortunately, I have to report that I ran a new purple/yellow wire from the starter to the + coil post because as you are probably aware the purple/yellow wire and solid purple resistance wire are...

    Actually due to the condition of that manual I scanned the whole thing. Here is a better image w/ the solid purple resistor wire path(s) highlighted with red arrows

    This set up is a little different than the 3.0. But I see the broken line purple wire is what you are referring to. The only concern that comes to mind is that on the 3.0 the purple wire seems to branch from the coil with one branch going to the choke and the other to the alternator. Do you have...
