    Wiring question for 4.3l Merc

    Okay great to know. Somewhere after the igniton and before the plug i'm losing power. I ran a new wire from after the igintion, spliced into the purple, and back into purple before the plug and now everything works fine. I'll try to keep looking for where the issue is tomorrow.

    Wiring question for 4.3l Merc

    Okay so after looking at that and doing some testing, somehow there's no power at the plug on the engine (cannon plug), once I applied power there the pump runs. But somehow there's power at the alternator? Not sure what's happening. Anyways, power at the key, but not at the plug, i checked all...

    Okay here are my findings. No power at coil, no power at fuel pump and no power at oil pressure switch, power at purple wire at alternator and power at purple wire at ignition key.

    Wiring question for 4.3l Merc

    Thank you for the diagram.. So according to this if i have my oil pressure switch bypassed, i should be getting power to the pump at ignition, before i even crank? But I'm not, where should i be looking for loss of power?

    Wiring question for 4.3l Merc

    Thank you both for the replies. I will try to look up the serial number, but i do think it's the TKS carb. Bondo, before this happened, my fuel pump would make noise when key is in the on position before i crank.. now nothing when crank or otherwise. So today, i went to clean all connections...

    Wiring question for 4.3l Merc

    Aloha, I have a 2005 4.3l Merc engine, yesterday randomly the fuel pump stopped getting voltage. I energized the pump and it works. I bridged the oil pressure sensor, that's not it. I traced it back to the starter wire that is purple and yellow. Now i know from before when i turn the key...

    Replacing carb question

    2004 Merc 4.3l, started dying at idle, fine at throttle. I'm pretty sure it's the carb, just had the plugs and wires / cap replaced 6 months ago. I don't want to deal with rebuilding the carb, but I can't seem to figure out what my replacement is? A lot of listed carbs say it's for 4.3l Merc...

    Metal coming out from around gimbal bearing

    I took my alpha one gen 2 drive off to do some work, and I noticed that metal that's ribbed that comes around the gimbal bearing is sticking out from the top of it. I tried to take a picture hopefully it's visible. What could have caused this, and how bad is this issue? I ordered a new one.

    Drive oil container empty / sludge inside.

    Thanks, I guess I just panicked because loss of oil is something I lose sleep over! I might top it off and clean the sludge and see what happens

    Drive oil container empty / sludge inside.

    There was oil in the reservoir, but after taking the boat out the first time, when I came back the reservoir tank fell off the bracket and was on the ground, so I put it back on, still had oil in it though The ramp is about a 2 min drive through a no wake zone. Thank you for the replies

    Drive oil container empty / sludge inside.

    4.3 Merc 2005 Alpha one g2 drive I had the boat in the shop to replace the u-joint (making knocking noise when turning hard left or right). So I put the boat in the water and drive it, come back a week later and find the drive oil container empty and brown sludge inside. What could be the...

    4.3 dies after 5-10 sec running

    2004 4.3l mercruiser, rebuilt last year. I replaced the gimbal bearing a month ago, and didn't get a chance to use the boat until today, it sat. Today I put it in the water and start it and it died after 10 seconds. Every time I run it, it dies 5-10 seconds later, does not pop or sputter when...

    Merc 4.3l timing question, BTDC mark

    Thank you everyone for the replies, makes sense now, just wanted to make sure I didn't screw up ign timing. I set it at 10 BTDC at 650rpm, seems to be running well.

    Merc 4.3l timing question, BTDC mark

    To add, on my timing gun there's an advance option, when I set it at 10, with the pulley showing 0, when I set the gun to 0, the pulley goes to 10, on the right of the 0 mark, but everything I read online says BTDC is on the left when looking at the engine, not sure why I'm confused by this

    Merc 4.3l timing question, BTDC mark

    This will probably be a dumb question, but in the image BTDC is on the side where the 6 is correct? I ask because I need to see the timing to 10 BTDC but why would there not be a mark for 10 on that side, but one on the other side?
