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

I got this off west marine website.
4.3LX (GEN II) (4 BBL.) GM 262 V-6 1993-1995
0F001220 THRU 0F601126.
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.

0F277120 = 1994 MERCRUISER TB4, W/PS, TWOPCEX, WORO 4.3LX ALPHA (262 Cid) Gen Ii) Model number 443L100GS

Parts guide part number 90-80187493

Okay so 0F277120 and 443L100GS is the same. Thank you for your help!
