12V DC 300W 25A Hotstart OW model immersion lube oil heater is engineered for weathertight engine applications.

This heater features: 21.4 watts per square inch power density, a 1 in NPT mounting, 5-3/8 in (136 mm) probe, 5–15 gal (19–57 L) oil capacity, no thermostat. This heater is suitable for medium size engines.

DC oil heaters can be powered directly from the battery, but will drain the battery very rapidly unless charged by an alternator or generator.

Since this heater has no thermostat, Hotstart recommends using a remote thermostat to protect the oil from overheating. When used with a thermostat control, all DC oil heaters must use a DC relay.
