3
✔✔ It provides a constant reading of the oil pressure, ensuring that the lubrication system is functioning correctly
What is the typical viscosity range for marine engine oils?✔✔ Oils with a viscosity that allows smooth operation under varying temperatures and pressures, often 30 to 50 centistokes
What should you do if the oil pressure drops below normal levels?✔✔ Investigate for potential oil leaks, low oil levels, or a malfunctioning oil pump
What is the purpose of the crankcase ventilation system in a marine engine?✔✔ To expel gases and maintain pressure balance inside the engine
What does an "oil change interval" refer to in marine engine maintenance?✔✔ The recommended time or usage threshold after which the oil should be replaced for optimal performance
Why should oil filters be replaced regularly on marine engines? 3 / 4
