    Cracked block, exhaust manifolds and heads Mercruiser 4.3 v6 1984

    The boat I got for the drivetrain appeared to be a total bust. Both exhaust manifolds, block and at least one head had cracks which I discovered after taking apart the engine. I'm kinda pissed off and will talk with the seller about this crap. However, I wondered, is there anything that I could...

    Gasket for thermostat housing?

    I looked at the rebuild kit for mercruiser 4.3 v6 and in both kits could not find a thermostat to block. I was almost 100% sure that there should be one, but then I thought that this gasket could be rtv sealant one. So, obvious question is, do I need a gasket or is it RTV gasket maker one? Thx.

    Extension for the engine stand standoffs

    The stand I'm using for my 4.3 v6 Mercruiser has some short standoffs, standard type. They do not let me install a flywheel to test the engine. I was looking for a longer set of standoff mounts but they are quite expensive and cost more than a used stand. I wondered if I can use right diameter...

    Mercruiser 4.3 v6 dipstick pipe does not fit into a Chevy 4.3 v6 block

    I thought that Chevy and Mercruiser 4.3 V6 pre-vortec blocks are exactly the same, it is the accessories and other parts are different. But today I tried to fit dipstick pipe from Mercruiser into a chevy block and looks like the hole in the Chevy block is a little smaller than that in...

    1993 Mercruiser 4.3 v6 temperature sending unit

    I am assembling 1993 mercruiser 4.3 v6. I had a block with heads and to get accessories I bought an older 1986 Larsen with 4.3 v6 engine. However there are some differences. One of them is the location of the water temperature sender. On the newer engine it is in the thermostat assembly, and...

    Mercruiser 4.3 v6 Oil Pan installation

    I looked at the manual for installation of the oil pan with a new gasket. It says to use some RTV gasket silicon at the oil rear seal and the front timing cover at the joints. I wonder if this silicone should be put under the gasket or between the oil rear seal and the block and between the...

    1993 4.3 v6 rocker arm support

    Im rebuilding this engine, 1993 4.3 v6 GM. I noticed that 2002 4.3 v6 has a rocker arm support piece that goes under the rocker arms. However the 1993 block does not seem to have any support. Or is this part just missing, since the heads for this block I bought separately and the previous owner...

    I just got a new timing cover (plastic one) for 4.3 v6 vortec mercruiser. It looks like there is a seal already installed n the groove, but the cover came with gasket maker little package. I tied to look at the Seloc manual but it is useless. So, do I need to use the gasket maker with the...

    Building an engine test stand

    I realized that it saves a lot of efforts and time to test run the engine before installation, after I got one installed with a bad rear seal. Cursed all the way removing this engine. It started leaking about after 30 mins of running in water. So I decided to build an engine stand, with a...

    Oil Pickup and oil pan from automotive 4.3 v6 in marine engine

    Im trying to rebuild a 2002 vortec chevy 4.3 v6 to make a marine engine out of it. Got the marine rebuild kit, marine camshaft, intake manifold for a 2bbl carb with mercarb. Now, the oil pickup in marine engines is much bigger than the one in the automotive. I can buy a marine pickup for $20...

    I am rebuilding 2002 Mercruiser 4.3 v6. I started with freeze plugs a while ago and was waiting for the rebuild kit.

    cracked exhaust manifold on 4.3 v6 mercruiser

    I started the engine Mercruiser 4.3 v6 on the boat I recently purchased (1985 Larsen). The engine (at least some parts of it, not the block itself) and outdrive I was going to put into my newer 2005 Larsen boat, which has no drivetrain. So this engine appears to run (surprisingly since it was...

    Adjusting trim level and trim limit senders

    I recently changed the bellows on my Alpha one gen 2 outdrive. I put the old trim limit and trim level senders. However, looks like they require adjustment since the trim level gauge does not show the outdrive movement, it is stuck in the top position. I looked online for the sending unit...
