I am glad I could help.

If the alarm is coming on because of low oil in the small reservoir and filling the small reservoir manual solves the problem work backwards. Line to main tank, oil pump failure on tank beside filter, filter is the cheap fix and line from filter to inside of the tank. It is plugged up somewhere along the way or the pump failed.

I suggest hooking power directly to the pump motor that is on the side. You can use two small jumper wires. If the pump works the issue may be a clogged line. If not replace the pump motor.

The problem is with the filter blocked the oil could not flow from the reservoir to the motor reservoir.

Was that your issue

Glad it helped and hope it saved you some time.

Did it solve your issue and if not let me know how I can help.

Thank you for watching and we hope it helps.

Nice what synthetic oil are you using now and what’s your engine?

Glad I could help!

I am using both Yamaha and Mercury synthetic on a 20 year old 150 but changing the filter is cheap maintenance.

Where's u guys purchase that filter, link please, thank you....

You can use the lower tank oil in the upper tank. The motor on the lower tank pumps to the upper tank. When the upper tank gets low the alarm will go off. Filling the upper tank manually with temporarily solve for the alarm. I bought my filter from my local dealer but you can get them on Amazon or eBay also.

@@ECUBountyHunter thanks for responding back, appreciate it. Do u ever change the oil from the oil reservoir tank, or u just leave it in there ?

@@ECUBountyHunter thats prob y my alarm keeps goin off 🤔🤔🤔🤔🤔

@@teamslaiyans3808 no reason to change it becuase it gets burned in the outboard. If it is contaminated with water or trash then drain it and fill with fresh oil.

@@ECUBountyHunter ok, thanks........ 👍👍👍👍👍

Change the filter with the oil in it. There is little to no oil loss. My motor is a 1999 Saltwater series II but this is an annual maintenance item for most two stroke oil injection motors.

@@ECUBountyHunter I wonder if mine is the pump or the filter? Also if mine is set up the same way.

@@ECUBountyHunter did you ever have the motor go out?

My motor has never gone out but try the filter first. Change the filter, draw down the tank on the motor to a lower level and turn on your key. It should start pumping oil to the motor oil tank. If not hook two jumper wires to the tank pump and see if it will run. If not you need to replace the motor.

That may be beyond my ability but if there is oil in the tank on the motor the problem is from that tank to the engine. You can premix to avoid engine damage until you resolve but it will not turn off the alarm. The alarm I am speaking to related to the low oil level alarm tied to the small tank on the motor. Consult your local mechanic.

Thank you NCOutdoors. That is the correct part number.

@@huntersorrell1216 thanks

I just got one from Amazon. Yamaha 646-24251-01-00 Strainer 1, (2-stroke outboard motor oil filter); New # 646-24251-02-00 Made by Yamaha

The switch is on the back of the motor

@@terryfonz4603 wheres the switch located on the motor?

815100 was my number. If you unbolt the tank, the number is printed on the pump motor. The filter is under $20 the pump is closer to $150. You can use a pair of jumper wires when you disconnect the pump wires and run it direct to test the motor.

@@ECUBountyHunter when I bought my boat I got these alarms.. got her back.. and called a recommended boat guy.. he said the reserve motor was shot. My boat would bog down as well but he installed a manual bulb to pump the oil to the motor reservoir. He said he tested the motor and it was shot... that hes never been able to locate one for other clients. The boat since I got it has always bogged down under throttle surging really. I wonder if this creates some sort of pressure my manual bulb cant replicate. I dont have the motor any longer to check. I'll see if theres one on the reserve.

@@Ryanboehmer the bogging has nothing to do with oil. If there is oil in the upper reservoir you have oil. It is really simple. Bogging could be caused by bad power packs, cracked block any number of things but not the oil transfer.

sorry for the late reply. start with the filter as ita a cheap fix. you should be able to feel of hear the pump run when you turn in the ignition if the oil on the motor tank is low.

@@ECUBountyHunter my oil pump won't work from the fill switch but when i hot wire pump to the battery it works. any ideas? i have done checks on the level floats on the motor oil tank and on the tank level float they both work. i have also checked that i am getting power to the wiring harness 12v when i use the emergency switch mounted on the motor. I am really puzzled by this any help would be greatly appreciated. thanks and good video.

@@byrongilcrease have you check the switch to make sure it has not gone bad. It's hard to diagnose without hands on.

@@ECUBountyHunter I am searching the web for a troubleshooting guide for that switch now. If I find any i'll let you know. Thanks

If the switches on the back of the motor activates the pump and they fill then your pumps are good and filter not clogged. Check the floats that activate the switches. I have sold my motor and cannot look and reference it. It has to be what activates the switches has gone bad or is stuck.
