Sierra 18-3030 Impeller for Chrysler/Force 125 HP and 140 HP Outboards, Replaces 47-803630T, F523065

The Sierra 18-3030 is a water pump impeller built for Chrysler/Force outboard motors, designed to circulate cooling water through the engine and keep operating temperatures in check. The impeller features a machined exterior and is manufactured to meet or exceed original equipment quality, making it a reliable choice when rebuilding a water pump housing during routine maintenance or after a cooling system failure.

This impeller is engineered as a direct fit for Chrysler/Force 125 HP outboards built from 1981 to 1989 (all models except model C for 1988, which uses this same part number separately) and 140 HP outboards built from 1978 to 1982. It is the correct replacement part for anyone rebuilding the lower unit water pump on these outboards, and it cross-references directly to the OEM Chrysler/Force part numbers below, so it drops in without modification.
