Re: 80 hp merc -oil injected
river<br /> with maint, and yes the oiling system is a maint requiring subsystem, the oiling system on you 80 is very reliable. the clear plastic lines require periodic replacement, the fuel pump and the oil line check valve do to. most the time it gets done at the rebuid of the engine. pistons rarely fail just cause. usually its just cause a subsytem failed causing the reciprocating parts to fail. when you change the lines its a good time to clean the tank.
