Model number of the Engines

[mahmudengbd]

Dear Exparts,

Please let me know the
Difference between the Verado engine model number 1250V33ED & 1250V34ED

And what is meant by the following 2 codes: L6SC 250 XXL 4 or L6SC 250 CXXL 4

If you will go to the Mercury parts.com parts catalog and input your motors serial number, it will tell you everything you need to know.
On the L6SC 250 CXXL I am pretty sure that the C in the CXXL stands for Counter rotation.
But the complete description should be available when you input the serial number into the parts catalog
