    Help me be the hero :-), Mercury 4.3 – no spark

    I just went thru this on my boat, 2003 4.3L TB- V ignition. Went thru the steps and it was the ign sensor inside the distributor. Mine was the original two wire sensor so got a three wire replacement quicksilver sensor and new cap and rotor. The cap contact points were all corroded so I am not...

    2003 4.3L warning alarm horn TB-V alpha

    Correct, only three things are monitored by the alarm, this is according to the label on the throttle control. This has no plug in port to monitor engine parameters, it is before that time. My two water temp sensors in the housing has two wires on one and the other has one wire. Thanks

    2003 4.3L warning alarm horn TB-V alpha

    I am not the type to let an alarm go but when the engine and gages look to be in range I figured it must have been a switch going bad or wire off. The out drive oil was in range in the reservoir, the oil pressure increased with engine rpm, the manifolds didn't get any hotter than they normally...

    2003 4.3L warning alarm horn TB-V alpha

    Took the boat out to the lake after replacing the battery and + battery cable. Turned the run switch on located on the throttle control. Turned ign switch to on position and continuous horn went off (all is normal). Then turned ign to start and started but the alarm continued to sound. All the...

    ENGINE NOT STARTING...KICKING MY BUT

    Just to let you know it was the bolt I removed from the shift linkage for the new ground wire must have slightly changed the Linkage position enough to where I couldn't move the shifter. Go figure. Moved the ground wire to a new location and all is working fine. Hope this can help someone else.

    ENGINE NOT STARTING...KICKING MY BUT

    Ok guys, another issue here. Hope you can help. Engine starts fine and runs good but I cannot get the shift lever to move in forward gear or reverse. If you read the above posts I replaced the ign sensor, cap and rotor. Not sure what this would have to do with the shifter unless it is tied to...

    4.3L IGNITION TIMING

    I'm no expert but this is what I found on another website. I definitely have a TB-V (at least that is what is printed on the air cleaner) all factory stock. I did find the purple and white wire with a black plug in the connector. So I grounded that wire and set timing at idle which didn't take...

    4.3L IGNITION TIMING

    Just looked at I only have a green/white and red/white coming from the module going to the distributor. Is this purple / white wire somewhere else? Where is it located?

    4.3L IGNITION TIMING

    So is the purple / white wire grounded from the distributor or ign module?

    4.3L IGNITION TIMING

    And you do this by grounding one of the wires from the module to ground? I want to be sure of this so I don't fry the module. Thanks

    4.3L IGNITION TIMING

    I have TB-V ignition 2BLB carb engine and I just replaced ignition sensor and cap. I want to verify ignition timing. It states 10 deg BTDC but what rpm is this at, the timing changes depending on the rpm. It also states on the air cleaner that special ignition timing is required. Thanks

    ENGINE NOT STARTING...KICKING MY BUT

    Instead of breaking the new sensor bc I couldn't angle it enough with the shaft to get it in I removed the c clip on the shaft, then loosened the dist bolt but marking the dist before it moved. Then lifted the housing enough to where the shaft was sticking thru an 1inch and dropped the sensor in...

    ENGINE NOT STARTING...KICKING MY BUT

    Ok, now that I have the new sensor what is the trick for getting it installed? It almost looks like I have to remove the shaft for clearance. Thanks
