Need help to identify 5.7l v8 engine

Hello,

I need help identify my boat engine. I have the serial number of it, but I am not sure how I can identify the engine with the serial number. I attached some pictures.

Thank you for the help, but I was thinking it was this one https://www.crowleymarine.com/mercury-outboard/1014.cfm?mdl=XA5NUC&q=0F370092

Both are showing the same listing

Nola's link list 0B serial numbers but looking further down on the page it shows the correct parts and list 141 different motors

s_explorer list the actual serial number yet shows same parts

Can go to Merc parts and find same serial number listing (1988 to 1995) and it to shows same parts. They are all merged together. As example they all show the 3 different thermostat housing
