Caterpillar C32[1]
Caterpillar engine. On the right, there is a cylindrical oil filter and on slightly below the middle left also two oil filters side by side. "CAT 1R-1808 - Advanced" reads on these filters. On the bottom, it reads "CAT C32 MARINE ENGINE". On the upper right there is a black plate reading "CAT C32" along with some unreadable text. Several white quality check stickers are glued on the engine.
