Need help identifying type of motor and model

[Nicyutrick]

Hello everyone I’m new to the boat world. Just bought a 94 chaparral 1830ss. I believe the type of engine I have off what I’ve researched is this:
4.3LX (GEN II) (4 BBL.) GM 262 V-6 1993-1995.
0F001220 THRU 0F601126
From what I know it is a Mercruiser 4.3l LX v6 Thunderbolt IV Ignition Alpha One stern drive Gen 2.

I will add pictures of the serial numbers to this post as well. My main concern is when I go on Crowley Marine website, I enter all the engine info I have but then it asks for the model numbers and it throws me off because it doesn’t match anything I’ve searched up.
Can someone please clarify engine selection & model numbers on Crowley marine website. I will post the pictures as well at the end. Also if you don’t use Crowley marine website, what website do you use?

Thanks In advance

serial number comes 1993-1995 4.3. either 2 barrel or 4 barrel.

But when I go to Crowley marine website I see these model numbers which throws me off.

Some sites use the model number to help with parts look up which is pretty much the original part number of the whole engine from new. You're good with using/trusting that site for parts info.

This is 2 barrel though right? I believe mine is 4bbl

This is 2 barrel though right? I believe mine is 4bbl

And the difference is just the intake and carb

The base motor is still a GM 4.3 assembled in Tonawanda NY.

Looked up using the SN range. But main jest was, that site has a couple different ways for a lookup. Basically wanted to get you the web link. YMMV.

Here is the '94 4bbl https://www.mercruiserparts.com/4-3lx-gen-ii-4-bbl-gm-262-v-6-1993

Here are all the V6's https://www.mercruiserparts.com/v-6-sterndrive-engines

Right on thank you

Specifically, what are you looking for?

Specifically, what are you looking for?

I was looking for an impeller kit, elbow exhaust gasket, and bellow replacement kit. Got all of it though and called nuwave to verify and it was good
