Oil Lubrication System

The lubrication system features two oil pumps. The first pump is the low pressure pump that pumps oil to the

oil cooler, and then on to the oil storage tank. The second pump, high pressure, is located on the PTO end of

the engine crankcase. The high pressure pump draws oil in from the oil storage tank, and supplies oil to all of

the internal engine components. The low pressure pump supplies approximately twice the amount of oil to the

oil storage tank than what the high pressure pump requires. This ensures a constant supply of oil.
A small amount of pressurized oil is supplied to the turbocharger bearing house and oil storage tank anti--siphon

valve. The anti--siphon valve is located on top of the oil storage tank. The valve works by preventing oil from

the tank to back--feed into the engine in the even that oil pressure is lost. (Watercraft Rollover)
