Are Merc 4.3 inboards problematic?
It's a GMAre Merc 4.3 inboards problematic?
When people disregard the laws of physics and troll for the answer they've already convinced themselves exists?one of those hotly debated boating topics
Fair witnessIf maintained they can easily last 30 years or more.
Surprisingly not that commoncommon sense.
That is not the ignition module, it is the ignition sensor.I did have to replace the original ignition module under the distributor cap.
Good catch. I stand corrected. Ignition sensor.That is not the ignition module, it is the ignition sensor.
OP can get some good info from the stickies...........
But the 4.3L is soooooooooThe new one is completely sealed. Much better.
Ayuh,..... My 4.3LX has well over 2,000 hours, that I put on it, 'n when I pulled it to junk the boat a few weeks ago, it's still got over 130 psi compression on all 6 cylinders,.....Long story short…anyone that suggests or tells you that engines like the 4.3 gm (or most other of the usual marine GM like 3.0, 5.0, 5.7 etc) just don’t have the first clue about it. The 4.3 engine is simply undeniably amongst the most successful, reliable test of time proven engine ever put in a boat. Period. These things haven’t been put in enormous numbers of boats over the last 4 decades, for no good reason.
Not to mention the cheap as can be cost of maintenance.
There is just no arguing with these things in terms of their sheer numerous numbers and success rates, in terms of the amount of them still around from more than a life time ago for most.
Anyone that tells you these things and others of the same dna are troublesome…just either doesn’t know what they are talking about, has no idea around basic maintenance and consumable parts, or just watches far too much rubbish on YouTube featuring equally as silly people talking rubbish.
Huh?But the 4.3L is sooooooooo
Didn't you catch the OP question? Why is the GM 4.3L so terrible? Literally the worst engine ever created? Tell us......
Perhaps.I think dubs was being facetious lol. Sometimes humor is lost in posting!
