Oil in water?

Question

i have a 1989 evinrude 48 spl 2 stroke outboard motor. ive been having issues with oil comming out of water jets. i know its probably some seal that broke, but i was wondering what seal it may be, and what unit it may be (ie....lower, middle, or powerhead. ) im pretty possitive its motor oil. any help would be greatly appreciated!

Answer 1

might be a crack in the unit,what you think is motor oil is prolly,gear oil,not all outboards drain all the water when taken out of the lake,some have to be wintrized,like an inboard/outboard,

Answer 2

If it has trim check the seals>Or the lower unit seal under the water pump>Or prop seal> Fill screws leaking> Carb float leaks dripping gas & oil out exhaust>Fuel line or fitting leaking> Have fun>

Answer 3

Do you mean the water pick up holes?

If you do you most likely have a bad seal on the vertical shaft below the water pump.

Answer 4

I don't believe you have oil injection on that motor so any oil would be lower unit oil. DO NOT USE TILL YOU FIND OUT

Answer 5

the oil that passes out along with the water is unburned fuel residue.

2-cycle engines do not burn 100%  of their fuel intake. The exhaust housing is cooled by a double walled water jacket and by a fine spray of water mixing with the exhaust gases. The unburned oil leaves along with the tell tale water jet whose purpose is to indicate a working water pump. The oils slicks that you see on the water are the result of this unburned exhaust. That's why there's been a strong move to 4-cycle outboards.

Answer 6

head gasket if its a two stroke engine

Answer 7

i would have to say its comming from your lower unit . have you checked the level? or maybe is it 2 stroke oil . do you have to mix the gas & oil or is it injecked?
