Molded Coolant Hose 32-33189 for Mercruiser OMC 4.3L 5.0L 5.7L with Clamps
Molded Coolant Hose 32-33189 for Mercruiser OMC 4.3L 5.0L 5.7L with Clamps
Product Overview
Molded circulation pump hose, a pre-formed coolant hose for MerCruiser and OMC sterndrive and inboard engines from 3.8 L to 5.7 L, supplied with two stainless clamps. It replaces MerCruiser 32-33189, 32-33189A1 and 32-87108, OMC 0910205 and 0312781 (also written 312781), Sierra 18-71337 and Mallory 9-44052. The hose has a 1 3/4 in (44.5 mm) inside diameter and is 12 3/4 in (323.9 mm) long, moulded to the shape of the circulation pump outlet so it clears the front engine mount without kinking. A straight length of hose will collapse at that bend and starve the pump, which is why this one is pre-formed.
