    4.3 running great accelerated slowly died. No power at key, no click, nothing.

    Was running great, new Coil, new timing with jumper, new Carb with electric choke, fresh non ethonal. New Battery's, fully charged, (2). On acceleration it acted sluggish then lost power and died. No sputter or pop or bog, just died. Tried the ignition, nothing. No gauges either.

    Not cocky. Sorry if I called you out and you got your feeling hurt. None of you suggested the jumper needed to set the timing correctly in this engine. Bad advice from non mechanics is a lesson learned.

    4.3 runs great for about 30 minutes then bogs, pops won't accelerate

    It was the timing. On the 4.3 mercruiser you have to use a jumper on the distributer to clear the base timing. Regular old school timing won't work on this engine. Problem solved!!!

    4.3 runs great for about 30 minutes then bogs, pops won't accelerate

    4.3 runs great for about 30 minutes then bogs, pops won't accelerate

    Boat runs great for 30 minutes then pops and bogs. Won't accelerate above idle. My mechanic has figured the carb timing was not done right. Here's what a member said. Is he right that this should remedy my issue? You need to put it in base mode before setting the timing to 10 BTDC.Just look for...

    2007 4.3 TKS Timing Procedure

    I've had an issue with my 4.3 mercruiser popping and bogging after running great for 30 minutes. My Mechanic feels the Carb was messed with and wasn't set right. What's your thoughts?

    4.3 runs great for about 30 minutes then bogs, pops won't accelerate

    The mechanic's taking out on the water to do diagnostics. I guess I'll find out what the result will be by the end of the day. I can't keep guessing. No, the problem was before I exchange the carburetor.

    Replaced TKS carb with new correct electric choke carb. New fuel/ water filter, timing good, drained old gas filled with non-ethanol. Starts and runs great for 30 minutes then pops and bogs. Will idle but won't accelerate. Can put it in neutral and it revs fine. Any help????
