Recmar Honda 19300-ZV5-043 Thermostat

72°C / 162°F replacement thermostat for selected Honda four-stroke outboards

RECMAR aftermarket thermostat replacing Honda 19300-ZV5-043 and earlier ZV5 revisions. The strongest confirmed application is selected BF25, BF30, BF35, BF40, BF45 and BF50 four-stroke families. The previous Tohatsu identification was incorrect.

Fitment check: Confirm the Honda model and OEM number. Some aftermarket charts extend this cross-reference to larger BF models, but the engine-specific Honda catalogue takes precedence.

  • For selected Honda BF25–BF50 four-stroke outboards
