Raw water pump STM6109 for Vetus Diesel 2-cylinder and 3-cylinder M-Series engines (not M2.05 or M3.10), including:
- M2.02, M2.04, M2.06, M2.13, M2.18, M2.C5 & M2D5
- M3.09, M3.28 & M3.29
If a complete water pump is ordered, this will be supplied as the new type pump STM6109B with a round faceplate (2026 onwards) - this is a direct replacement for both the original pump with the round faceplate and the later pump with a triangular faceplate. These pumps share virtually all the same internal parts, with the main difference being the front plate gasket / o-ring.
