Changing the oil regularly is among the most cost-effective way to protect an engine. If you own a performance boat, you should change the oil and filter about every 50 hours or at least once per season. Besides fitting all GM 6.0/6.2-liter engines below S/N 164786, the 872023 Oil Filter from Bakes Marine works as an Indmar 5.7 oil filter. As a Pennzoil oil filter guide, it replaces the Pennzoil PZ52 and PZ3. For further information, check an Indmar oil filter cross reference or Pennzoil oil filter cross-reference chart.
