Fitment

Mercury

This is a Mercury 2.5L V6 DFI / Optimax vapor separator tank (VST), identified by cap casting 850250-C1 and bowl casting 850249-C1. Mercury used these housing castings across the 2.5L DFI range — roughly 115 to 225 HP — under several assembly part numbers (855432A2, 855432A1, 855432A06, 859174T06 and others). Because this unit carries casting numbers only, we cannot confirm the exact horsepower it was originally calibrated for. Please verify against your engine’s serial number and application before purchasing. The dual-pump setup (external low-pressure and internal high-pressure) is common to this DFI VST line.

1Year Warranty

This part is sold with a 1 year warranty from the date of purchase, provided by Southcentral Outboards, covering the pumps and unit function. The filter is not included and the gasket is a recommended replacement — these are normal service items and are not covered. If the unit does not work within the warranty period, we will replace it; if a replacement is not available, we will provide a refund.
