- What to do when your Yamaha outboard alarm going off and cuts the engine to half power is first replace the oil reservoir filter. After the replacement and you cut the ignition switch on it will start pumping oil to the motor mounted reservoir. If this doesn't work check your pump on the reservoir.

Thank you. We were on the lake last night with our Yamaha VMAX 150 and an alarm started going off and the power to the engine dropped. Googled two stroke boat alarm and this video popped up. We had spare oil on the boat and used it to add to the small tank at the engine and were able to get back to our slip.
I am glad I could help.
Thank you for the information!! You saved me allot of work by knowing what I needed to remove (the 10MM bolt & containing bracket), then the filter. You made a hard job easy, even giving the parts numbers! Thanks LOADS!! Bob
Thank you. This helped me out. In addition to this I found that my supply hose (discharge the pump) was slightly pinched on a bolt just past where all the wires/tubes enter the engine. After unpinching I think I bought some time until the filter arrives. I luckily was able to fill the reservoir twice to finish the boat trip.
This was a great tip after I have sent boat twice to get fixed paid twice and waited on it fixed me right up my self
Short very informative and to the point, plus it was exactly what mine was doing.
Thank you!!!!!
After changing your oil filter/strainer, add a filter to the fill port in the reserve tank, one is easy made from a strainer, and add a coffee filter in it, replace coffee filter as needed, even paint strainers work, yes it takes more time filling the oil tank, but no trash. All oil bottles have a foil seal, that trash can end up in your oil!
Thanks , this will help me with my annual maintenace.
This was VERY helpful! Thank you! Unfortunately I am still getting the alarm when I run. Assuming that my oil level gauge assembly should be replaced or even the pump itself, but after reading some of the comments I think checking for any kinks in the line should come first. I don't think there are any other things that could be causing the alarm because it turns of within 1 minute of it turning on and restricting my throttle. Only thing wrong with the boat been trying to fix this a while without bringing it to a shop and getting slammed with a hefty bill that I could have done myself
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.
Thanks for the video this incident happened to me today all good then the alarm went off il check that filter tommorow thank u
Good tip, pinched hose was my problem
Great Video! I hope this is the fix I need. Will let you know.
Did it solve your issue and if not let me know how I can help.
Great video, i changed my filter, but still the same issue, i might need to take it to the mechanic
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.
You video worked. Thanks for the fix
Gregg there is a toggle switch on the left side under the metal bracket on back of the engine the will turn on your pump on the reservoir tank to fill up the small tank on engine.
The problem is with the filter blocked the oil could not flow from the reservoir to the motor reservoir.
Was that your issue
exactly my problem Thank youi!!!! easy fix
Glad it helped and hope it saved you some time.
You just saved me!!! Thank you!!!
Glad I could help!
I was warned about using yamaha 2 stroke oil and some of the other non synthetic ones by the previous owner of my boat and he said after switching to synthetic 2 stroke oil that little filter has had no issues.
Nice what synthetic oil are you using now and what’s your engine?
Great Video,,,, Thanks!
Thank you for watching and we hope it helps.
thank you.

First thing that you do is to take off the cowling while the engine is alarming to verify that the engine oil reservoir is in fact actually low on oil.
Greg, does the lower/external oil tank need to be empty or can you clamp of the hose while you replace the fuel filter? Thank you.
We have added a link to the filter in the video description.
What brand of oil are you using that your filter gets clogged every year I change that filter every 500 hours and I have never seen that filter clogged in my 20 year old 250 OX66.
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....
Aside from blowing my 150 Yamaha engine how can I tell if the engine is getting oil? It's a 1994 model (2 stroke) and my low oil alarm is going off but both reservoirs are full. I checked the remote oil pump and it's pumping oil up to the engine mounted reservoir. I'm not sure what to check next. I don't have the expertise to know if the engine is actually getting oil and maybe I have a sensor problem.
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.
Can i use the lower unit oil into that upper oil reservoir tank also ? And whats the link for that filter ??? Thanks.... great vid !
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........ 👍👍👍👍👍
What is the part number fellas ? Thanks great video !! All the best from Canada ice just about off the lake 👍🙈
G & G 646-24251-02
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
Hey man.....I have this problem...started in a tournament. I figured out the fill the motor manually....but....2 questions. #1 do you have to drain the oil tank in your boat, or, can you change the filter with oil in it?
#2 what year Yamaha vmax is it?
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.
Give the whole story! If you fill the tank on the motor you need to line up the arrows when you reinstall that cap that pops off that’s important. There’s a bitch but there’s some arrows to line up from the cover to the cap.
Then it’s not always the filter. Those pump motors go out also as I’ve learned last year changed the filter this year it was the pump.
Also there’s a switch to manually fill the onboard reservoir if the pump is working.
The switch is on the back of the motor
@@terryfonz4603 wheres the switch located on the motor?
I never heard of this filter. 2 stroke?
What is part number? They all the same? I need 2001 Yamaha 150hp. VMax
I have the 99 OX66 150’s. Low oil alarm comes on and I have to use the switch on the back of the motors to refill. Both remote tanks are full. What do you think?
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.
perfect mine did this late weekend trying to get back to weight in almost was late !!
What's the part # for the oil feed pump?
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.
My boat has the same problem but how do I know if the problem is the oil filter or the pump ?
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
