Evinrude oil injection

[snookhooked]

I have two questions. 1) I just bought a oil injection tank for my 92 150hp evinrude spit fire last week. I went out and bought the manual thinking it wouldn't be a hard job but the book tells me to have it done by a mech, so I went online to see what else I could find in pics for this deal and came across a website that rebuilds these types of engines I have and they do away with the oil injection. They say it has two most problems oil injection and fuel contamination. I wondering if I should just go to mixing gas and oil. my other question. since I'm new to the bigger boats I have this question. in the battery department where the bilge is, I have what I would call a oil filter like you would see on your car or truck. is this for filtering out the fuel and oil mixture? this system is on a 76 mako 20ft. if that makes any difference. Thanks

Re: Evinrude oil injection

fuel/water separating filter. many install their own oil tanks, it is not rocket science, or brain surgery. personally with a 92, i would get the OMS pump, or go premixed fuel.

Re: Evinrude oil injection

OK, I have a oil injection tank that I need to hook up but my problem is that I have a brown and black wire that are males type plugs. I have searched the engine over but cant find any females for those two. its a 1992 Evinrude Spitfire. Im looking for someone who maybe has more info to hooking it up all the info would help. Thanks

Re: Evinrude oil injection

Does the engine have the oil pump on it? The tank does you no good if the engine has had the oil pump removed in which case you must premix fuel.

Chances are you have the wrong model oil tank. In 1996 the SystemCheck warning system was introduced with 4 indicator lights on the gauge. The oil tank sender was a simple on-off float switch and had a plastic electrical connector on the end.

Earlier oil tanks (1995 on down) have a computer chip that generates a 20-30 second signal to tell that the oil level is low. Those tanks use black wires with bullet or knife type connection.

Re: Evinrude oil injection

I have a 92 motor and the oil injection I bought is a 93 yr. I do have the oil pump on this motor. it has both the fuel line and oil line. I just had to replace the connection on the side of the motor because the tips were broken off. the oil tank has two lines from it that are black and brown with the long looks like soldered ends. the lines themselves look to be at least 6ft in length. the tank came off a Evinrude. he up sized his engine so he went from a 1.8 to a 3 gal tanks. E150elenc is my model number for my engine. everything on it but it was missing the oil tank. I looked all around the engine for any hookups but didnt find any. if you need a picture of the motor and the tank, your welcome to email me at shawknee1@cox.net and I could email them. I never can get any pictures to post here. the diagram in the link is what I have. Thanks. I have looked around the pump and cant locate any wire loose for hooked up.

Re: Evinrude oil injection

Greetings,

There is no pump on the oil tank; it is a oil level sensor

The 2 wires from oil tank:
The one with the ring connector goes to engine ground
The other connector goes to the Tan head temp sensor circuit.

The warning horn depends on the year of the motor where the tank is coming from. More likely, if you have a solid constant beep, you have an older tank, if you have beep, beep, beep? then is around 92-95

Re: Evinrude oil injection

Thanks for the diagram. that's what I have. its a OMC tank. I have researched it and feel it would be better just to premix since Evinrude has a bad history of their oil tank stop working and end up blowing up the motor. even though it has worked so far. when they rebuild these motor, they discontinue the vro and go to premixing them. so if the re builders are doing this, then they must know something and Im going to do the same.Thanks for all the help and info

Re: Evinrude oil injection

99.99% of those stories about motors "blowing up" because of the oil injection are not true. Many more motors have "blown up" because the oil was manually mixed wrong or not at all.

Most "mechanics" blame the engine failure on the oil injection because they don't have a clue about what really caused the problem.

Re: Evinrude oil injection

Hey D,
How have you been doing? sorry I haven't emailed you. my computer crashed and I lost everything. as to the injection, Im just afraid to depend on it. this motor was rebuilt and that's a lot of money to loose if something was to fail on the part of the oil tank. its a omc tank, and they been saying that they are known to fail. I got through the break in and was back on my way home and some lady pulled out front of me causing a wreck which put me on hold getting both truck and boat fixed. I just got them back Tuesday, so I can go boating again. anyway, you believe in the oil injection? Im truly confused on what way to go on this? good to hear from you. stay in touch. Thanks

Re: Evinrude oil injection

Many, many motor failures are falsely blamed on a VRO or OMS system by a lot of folk that do not know any better. I find that a lot of "trained" outboard tech's will blame them for anything because they don't really understand them. The real tech's know differently but are few and far between.

Re: Evinrude oil injection

Man, what do I do? I know its working now. maybe give it some time. I know the vacuum fed so the only fault would be in the pump its self. just so many opinions out there both good and bad. I was also told the fuel side is something to think about too. is this just on the Evinrude side or other motors? Thanks
