Mercruiser 4.3 with internal crack

[@clutchboi4038]

Working on one for a customer and his was cracked in the valley same as this one. Found a new block and got it all rebuilt. Fixing to put it in the boat after i get everything assembled

[@mickypful]

Here in Northern Europe block cracks are a way of life through freezing , running on raw water. GM, wether MC or Volvo , V6 or V8 they take no prisoners and often don't show until hot. Many a 'new owner' have found that to their cost.

[@mumbles552]

Just like the Ford 351 Clevelands, cracking in the valley due to freezing.

Thats sad. I rebuild my 6.2 and I know how much work is in such an engine. Greetings from germany

[@darrylramey6442]

Were can I find a simple wiring diagram to test start and run like this?

[@THEGMDOCTOR-co9vp]

I would have thought this motor to be a roller motor was surprised to see it as a flat lifter

[@jonsmith7667]

odds are there is a crack in the bottom of the intake too where the coolant flows below the carb, usually don't have one without the other

[@MikeRembao]

Can anybody tell me why my relleller smokes like black and white smoke thanks

[@scottandcherylfreeone9539]

Ive seen guy cut v channels then JB weld them and have good results.

[@JasperRoossien]

How to start without contact slot

[@randyscott3386]

I know the major cause of cracked blocks is abuse and neglect by the owners , but I can't help but wonder . Do you see more Mercruisers with cracked blocks or Volvo Pentas with cracked blocks ?

[@vicentepena3617]

I know it’s been nine months but did you sell the exhaust manifold.

I just built a new 4.3 L MerCruiser what oil should I use since it’s brand new

[@falconeaterf15]

You built an engine but you don’t know what kind of oil it requires. Somehow I don’t think it’s going to matter much.

[@miguelfelizola8231]

Can you tell me the order of the cables to the distributor helmet?

[@ThinkLessBuildMore]

1,6,5,4,3,2

[@yess3776]

It’s funny I’m here cause someone sold us a blown engine

[@jsolo7576]

Just happened to me too. Engine block has a huge jb weld patch under the intake

[@markmcmahen9442]

@@jsolo7576 did it leak!? Lol if done correctly it will be fine.i have fixed several

[@jsolo7576]

@@markmcmahen9442 yea it did. Water mixed with fresh oil after operating the boat for about 30 mins

[@markmcmahen9442]

@@jsolo7576 sry that is not fun. I drill on each side of all the cracks, grind along them pretty deep with an aggressive Dremel bit Making sure it's free of oil and then coat it. I guess prep is a big part or I'm lucky. Lol I'm doing another 4.3 now and hopefully it works out. Thanks for the reply

[@3rdEye__FPV]

You swell all of your parts yet?

[@obi360]

Hi guy, i have a 4.3 L mercuiser engine too, but I dont what is the past number of elbow and menifold, would you let me know . Much appreciated.

[@josepeixoto3384]

[@larrywalden626]

That's some pretty bad lighting dude lol

[@benhalkon6478]

Can’t see what you’re looking at. Poorly shot video. Out of focus, shaky, no lighting. Shame as explanation quite good.

[@JasperRoossien]

Hey

[@Lightendog]

Sorry, this is my wife's channel........with the battery connected, just run a hot wire to the positive side of the coil, you could then use a screw driver to by-pass the solenoid.

[@dumpsterfire6351]

Seal it and run it

[@gregv6912]

Wow, in focus once, terrible video.
