Mercury has the oil capacity for this 1992 4.3 6 cylinder motor mercury GM motor at 4.5 quarts. So I change the filter and in pore in 4.5 quarts then run the motor, shut it off and check the dip stick.
This amount of oil is 1" over the full mark on the dip stick. It would seem that this particular Merc motor would not take 4 or less quarts oil which to me seems like too little oil. The dip stick is marked 41092-1 which seems to be the correct stick. Maybe Rinker changed the oil pan on that model for the motor to fit the boat. Does anyone know what the correct oil amount is for this year and type of motor? Any one have any info as to why this might be.
