    4.3l mercruiser no start when hot

    It stayed running after the gas was poured into the throat. The plugs are good the timing is correct.

    4.3l mercruiser no start when hot

    I thought I already posted about that. Yes the accelerator pump is working. Do you think running a higher octane gas would help? I usually run the cheap stuff.

    4.3l mercruiser no start when hot

    It will cough once but not start. Just checked spark on all cylinders after it warmed up. All 6 were sparking. Instead of using starting fluid I used gas as suggested set throttle wide open and after a couple revolutions it fired right up. Does this suggest the carb bowl running dry? If so do I...

    I’ll take the tester off and try looking at it with the wire off see how far I can get it off before it won’t jump.

    4.3l mercruiser no start when hot

    I’ve looked in the intake and do not see any fuel dripping out when it’s not running. When trying to start it hot I’ve tried throttle wide open and choke wide open. If the bowl was running dry why would it start right up after cooling down for a couple hours.

    I don’t know what the gap is set at. The tester has a light in it and the color is bright yellow/orange.

    4.3l mercruiser no start when hot

    When I pump the throttle I can hear the accelerator pump but I’ll check to see if anything is coming out. Any other suggestions in the meantime?

    4.3l mercruiser no start when hot

    It’s a 2001. I don’t know the serial number. The sticker on the flame arrestor is blank. I’ve tried pumping the throttle a couple times and it does not help. The boat is in my driveway on the muffs so it’s at idle the entire time. And if I shut it down and try to restart 5 minutes later it will...

    4.3l mercruiser no start when hot

    Motor will not start when hot. I have been reading other posts for months and trying to solve my issue. Engine starts great when cold but will not start after it has warmed up. I have been through the vaper lock scenario, tried starting with WOT, batter is good, have cleaned all +- connections...

    Water in gear lube

    I was able to replace them without removing the carrier. Is there a way to remove the retaining ring without the special socket? I tried using a punch and a hammer but it didn’t budge. I don’t want to break it but also don’t have $100 to spend a tool I will probably never use again.

    Water in gear lube

    I bought the seal kits yesterday with the gear lube (the good stuff) it came out to $170. Took everything apart last night and went to town on it. Does anyone have a trick to getting the prop shaft bearing carrier out that’s the only thing I could get off. So far it’s going good. Looks like the...
