Ayuh,... It appears the Only thing Merc is the outdrive,....

Yer 2nd picture shows everything there is Non- Merc....
'n as you've been told,... Merc has Never, Ever used a Holley carb...

Might be a OMC, or Volvo... I see blue paint specks...

Doesn't look like a flame arrestor either.

This thread is closed. Your other thread on this is in the Other Brands of I/O & Inboard Engines & Outdrives. You have an engine problem and it's NOT a Mercruiser. Mercruiser has never used the 5.8 or 460 with an Alpha drive, nor have they ever used a Holly carb.
Your engine could be a one of a number of manufacturers but not Mercruiser or Volvo. May even be a home made setup, who knows. But it is not a Mercruiser.
