Best video ever. Located the oil filter that I was planing to change. It fixed my problem. The system did not fill the resouvar tank because of the pressure drop in the old filter. With new filter it send the oil fast and filled up the tank. Thanks for the video man!
Thanks for the video and great breakdown, only thing is at the end where you used compressed air to 'recreate' the engine pumping oil, you can actually do that without compressed air with the engine off, it's a setting on the computer with a series of shifting from neutral to F, I forget what the exact combo is..
Interesting. So i did some homework after reading. Its key on, N, forward 5-10 times will prime the fuel and oil pump for 30sec. But will also out it into "break in" mode for 2 hours, which is whatever. I will drain and try to see if it fills that way also. If it does i will add an update to the last part of the video. Thank you for the info!
@@nsigarage5212 No worries! Thanks for looking up the sequence. I had a guy that used to work for Merc do it in front of me on my outboard thats how I knew. Another thing you might want to do as a pre-emptive measure is the float inside the oil tank, it's prone to eventually fail because the magnet separates from the float, and you will get 4 beeps as if no oil and the computer will put it in protection mode (low rev) when this happens. The cap on the sensor/float is sealed, but there is a guy that shows a hack here on youtube and how to fix the float. This will save you from future headaches on the water, and save you from having to buy a new tank again👊 It might even help your channel to do a better video of the repair. The camerawomen in the video is terrible, but the repair is solid. She eventually figures it out and moves in close to show the work at the end 🤦♂️.. Link -- th-cam.com/video/G8LWgGa7Kgg/w-d-xo.html
Pull the power to the ignition coils and crank it. It actually fills very fast. Or put ear muffs on it and just run it you will see how quick it actually fills. IF the tank does not fill make sure the air compressor on the motor is not bad, it was a know issue with these motors
@@nsigarage5212would it be ok to fill it with a small funnel? And then fire up the engine and let it bleed out the last bit of air before tightening the cap?
Do you need to take out all the oil from your bigger oil resevoir that’s on your boat first? The hoses you take off the small oil tank when you replace it from the motor won’t leak out since the bigger oil resevoir that’s on the boat is filled up ?
You do not need to empty the large tank, the small tank is higher than the large tank so they will not bleed out during the repair. Also I have an update to the bleeding procedure, unscrew the cap once the lines are back on and pour in some oil. Put the cap back on, put some water ears on the engine and start it. With it idling, just crack the cap and it will bleed the rest of the air in the tank fairly quickly.
Thanks ! Do you happen to know exactly which oil tank I need. I have a 2017 mercury 250 optimal 2stroke and I want to replace the oil tank that’s attached on the motor. But I see soo many different ones online idk which one to get.

@jordanpadilla99 mine is an 04 175. So I don't know how different they are I get the oil from mercury, or quicksilver which is made by mercury. I believe on mercs website you can find parts by the serial number (like a vin)
I call it a fuel manifold but some of them have a stainer 8M0122423 I believe is the part number. My motor is an 04 175hp V6 and I don't believe it has that stainer. It's easy to identify by it's red top
Great video NSI Garage. I have a 2001seadoo utopia jetboat same concept same issue was thinking of changing out the resivor tank like you did on your video .The big tank of oil is not Transferring to the small resivor on the side of engine but before I do want see if there something simple I can replace or try before going about that .it been a headache is there anything I can try before I replace the brass valve or whole resivor and if so where can I purchase one from Thanks🙏
I'm not sure if the seadoo uses pressure in big tank to transfer oil to the little tank. To here might be a small inline filter that is clogged, or something blocking the outlet of big tank. Anything you google would be the same thing I would find. If you send me more info to nosleepinc2020@gmail.com I might be able to help you further
@@nsigarage5212 thanks, trouble shooting low oil alarm with boat in the water (cam up while running offshore today) and didn't know if I have to wait 3 minutes or 30 but that is very helpful, thanks!
Can you go into detail on how to prime the reserve tank please? I keep the engine off… loosen cap on reserve tank, take cap off onboard tank and create pressure? Can I put muffs on engine and just loosen reserve reserve cap or will this be bad?
Thanks for the video. I have a 2001 225 Optimax and think I'm having a fuel delivery problem. How easy is it to remove the fuel filter with that line underneath? Thank you
You may need swing the fuel pump out of the way. To get better access. But the rubber line should push out of of way.. The layout of these engines change depending on year and HP rating. I believe yours might also have the fuel stainer that has a red cap.

@@nsigarage5212did you ever test the sequence? I’m curious if it worked out as I am swapping my tank this weekend
Honestly, just unplug the ignition coils and crank it over. It will fill fast than you think.
Thanks very nice video. Just what I was looking for 👍🏼
Going through this process with my boat. How can I refill the new onboard oil reservoir without an air compressor?

You cut away before it completely filled - do you fill until it starts leaking out the top and then screw the top plug back in?
It doesnt have to leak, if there is a small amout of air it will purge itself.
i have gone ahead and moved the end sceens further back
What is to the left of the fuel filter? Someone told me their might be a filter in that housing as well
I call it a fuel manifold but some of them have a stainer 8M0122423 I believe is the part number. My motor is an 04 175hp V6 and I don't believe it has that stainer.

Awesome video. How long does it take to for the engine to fill up that oil reservoir?
You can also just disconnect the injectors. Or put muffs on and run it. It fills pretty fast
@@nsigarage5212 thanks, trouble shooting low oil alarm with boat in the water (cam up while running offshore today) and didn't know if I have to wait 3 minutes or 30 but that is very helpful, thanks!
That's what mine was doing then I saw the oil
Can you go into detail on how to prime the reserve tank please? I keep the engine off… loosen cap on reserve tank, take cap off onboard tank and create pressure? Can I put muffs on engine and just loosen reserve reserve cap or will this be bad?
You can also just take off the cap and pre fill it. Put on muffs. And run it. It will fill pretty quick and self purge
@@nsigarage5212 thanks just completed the process. No oil alarm and oil spewing from pressure cap!
Awesome, glad I could help

how do you disconnect the blue wires to the oil reservoir without messing them up? thanks
It doesn't matter. It's just a contact switch in the reservoir
hello, NSI grage I am hasan from Indonesia, I want to ask about the problem of my 200hp EFI 2stroke mercury engine, My engine is emitting a lot of smoke when I start it up first, and what should I do and what should I fix and maybe what should I replace? and what
Hey hasan. Why don't you email me at nosleepinc2020@gmail.com. And I will see what I can do for you
@@nsigarage5212 ok.
What was the psi number you used for this procedure?
Just line pressure from my compressor. Probably 100, but just gave short bursts
Easier to remove the lower cowling first....?
I don't believe it comes off. It is one solid piece? Or part of the whole motor. I did this a few years ago I believe the only real trouble I had was that bolt
@@nsigarage5212 usually they can be removed.
I will have to take a closer look next time I have it off. I do know the spark plugs were a pain even with professional plug sockets
Do I have a problem if my oil tank isn't full ?
How not full?. It should fill within a few seconds of running
It's only about halfway full
There is an oil check valve.if it's stuck open it can allow oil to flow back to the holding tank . What year and HP is your motor, and serial number if you can find it. And I will do what I can to help.
