Yamaha 2 stroke oil pump

- Accessing and replacing the oil pump and motor on the sub oil tank. The sub oil tank is located inside the hull. It is the main reservoir that you usually fill with 2 stroke outboard engine oil. It pumps oil to a smaller tank located under the engine cowling. If it doesn’t fill the small tank, there is an emergency switch which powers the pump on the sub oil tank. If it still fails to fill you either have a restriction in the lines or a faulty pump/motor assembly. That was my issue. I was able to confirm I was getting 12 vdc to my motor but it still did not fill the small tank. After disassembling I discovered the magnets ,which are glued inside the motor housing had come loose and would not allow the motor to spin. I hope this information helps someone else out. I was not able to find much information on this problem but it really is not difficult once you know what’s going on.
I took this part out of my 06 Yamaha now I premix and I’ll never go back!
Why?? This and the suzuki / mikuni system is extremely reliable and easy to maintain. More issues with oil mixing properly in a bigger inboard tank than the oil injection gives by far!
@@ct1762 this!!
Excellent video! Thank you for sharing...
Super helpful. Thank you for taking the time to share this info.
Nice job, thank you for taking the time to share!
Thank You, I just PM’d my Skeeter SL210, and changed out that filter.
Very good video. Well done step by step thank you
Perfect explanation of what I’m looking for. Was trying to ohm coils this morning when I found the switch. I tried it and heard it pump. Took the boat out and it used all the oil out of the top reservoir until it got to the min level then sounded the alarm. We had to idle back to the launch. Guess my pump just went out…
I’m sure you figured this out by now but there is an emergency pump switch on the engine, it takes a while to pump but it gets there
Thanks mate i had a problem yesterday pump stuck keep pumping the oil. time i realise tank was all most empty thanks for sharing
It's useful to rig up a jumper lead to the battery and the pump and make sure it's the pump and not a wiring issue ..Nice video.Thankyou
How can you determine a wire issue. I replaced my pump and it’s still not working thanks
This video is excellent. I couldn't get the wiring harness disconnected until I watched this. Thank you! I replaced the pump, but it also seems I have a loss of current in the wiring harness as voltage drops below 12v over time. Regardless, excellent video. Thank you!
I’m glad it was useful! Wish I knew more about the wiring harness issue you’re having. I imagine there is a relay somewhere in the circuit which is energized by the float switches and in turn energizes the pump. Said relay would be a prime suspect! Good luck!
@@thomastaggart4581 Didn't think about the relay. Good advice.
@@thomastaggart4581 Any advice on where I can find the relay for the external oil pump? Pump works when hooked directly to a 12v battery. I ordered a new harness after shortening the old one to 3 feet and still getting 7 volts. I'm scanning the manual for the relay. Thanks!
@@virginiafishing1 Man I wish I had a diagram I could probably find it but unfortunately I don’t. Sorry!
That helped a ton ty!!
Where exactly does the blue end connect on the outboard motor? Where does the feeder tube connect on the outboard motor? Thanks for the fast reply !!!
All I can tell you is there is an identical blue connector on the engine wiring wiring harness under the cowling. The feeder tube runs up to the oil reservoir on the engine. Sorry I don’t have any more info on that!
Im putting everything new pump sensor
i put in the new pump and filter but it wont fill the upper tank automatically, only if I use the emergency toggle switch. what could it be? the pump was bad and wouldn't work even with the toggle switch before I changed it. So i know the pump is working now. Help
I am running into the same issue. Did you ever fix this problem?!
My remote oil tank is not connected. Where do I connect the wire with the blue ends when I bring it to the outboard motor ? And where do I connect the feeder tube. I have all the parts just not sure how to hook it up. Yamaha OX66 2 stroke.
Thanks.
The oil pump itself has a short blue wire and a short brown wire. They connect to the wiring harness that has a blue connector. I believe that cable will pass through the hull with all the other wires, cables,etc that go directly to the outboard. The feeder tube runs in the same bundle all the way to the oil reservoir on the engine.

🤔 seems like the switch should be relocated to the console with a low oil light from the engine.
The same should be done with the sub oil tank. It wouldn't take much to accomplish this. The time and hassles this would've save many people over the past 30+ years.
No. The gauge on the dash has oil level combined with an alarm for low oil and oil flow. If you don't have the gauge, it's an audible alarm only but 95% came with the gauge!
What was your issue. My boat run good no alarm going 20 mph but when I start going 40 mph the alarm comes on. I think the oil is not filling fast enough. Can you tell if the alarm is oil or over heating
Look in your manual. A steady tone is engine overheat. Intermittent is either low oil or no oil depending on alarm duration
My tank broke and I bought a new one. Does the sensor simply pry off the tank. Seems to be a very tight fit. Thanks!
Hey Jesse! Hope your repairs are going along nicely. Not sure which tank you had break but regardless, I’m pretty sure the sensor would just pull off. Having said that, I did not remove the sensor in the sub-oil tank, which is the one inside the hull of the boat.
@@thomastaggart4581 Talking about the sensor on the top of the sub oil tank. Thanks for the response
61A-85730-00-00 Boats.net shows this level sensor for the sub oil tank. Looks like it has a rubber bushing that fits into the top of the tank. Let us know how it goes. Good luck!
@@jesgord yes its tight. Pry it off.
HEY BROTHER IM YAMAHA HPDI 300 THE PROBLEM MY BOAT RUNNING NOT TRANSFER THO OIL TANK NEW SENSOR NEW PUMP NOT TRANSFER ARROW NOT WAT HAPPENED HELL M. EVRITING NEW SORRY MY ENGLISH not perfect
