Possible Causes:
1. Oil Filter Clogged: A clogged oil filter can restrict oil flow to the engine, causing the oil pressure to drop and the oil indicator light to come on.
2. Oil Pump Failure: If the oil pump fails, it will not be able to circulate oil through the engine, which will cause the oil pressure to drop and the oil indicator light to come on.
3. Low Oil Pressure: Low oil pressure can also occur if the oil level is too low, or if there is air in the oil system.
Solution:
1. Check the oil level. If the oil level is low, add oil to the engine. If the oil is milky, it may have water in it and should be changed immediately.
2. Check the oil filter. If the oil filter is dirty, replace it.
3. If the oil level and oil filter are both good, then you should have the oil pump checked by a qualified marine mechanic.
