My 2019 has same issue. The tech at Cabelas said, if your motor is "Making Oil" then your fuel pump is most likely the issue. Making oil he explained that the amount of oil is increasing with out adding oil. It's the fuel going into the motor. They test by using a pressure test and if the seals you show are bad then the pressure won't be correct.
Search model number online for a parts catalog. Get the part number from there. Then search boat engine parts distributors online. See if they have the part. Also, Amazon sells some parts. Sometimes I had to call marinas and asked if they could get it for me.
Your videos are very helpful, I have a 2007 mercury 9.9 four stroke and right under the fuel pump I am leaking oil when it is running, would this be a oil pan/ gasket issue?
@@MaineManBassing that is exactly what was missing, I used a O ring from an assortment I keep for working on cars and stopped the leak immediately, ran for about 10 minutes and not a drop, thanks for helping this new boat owners experience that much better, and a day closer to my maiden voyage of my highsider gheenoe, you rock🤘
Same symptoms you mentioned I changed and cleaned everything took this apart film of oil on the diaphragm, ordering one now life saver!❤
Thank you very much for the good videos! You’ve helped me out a lot
Happy to help!

Hello what's the part #? Having trouble it seems some pumps have only gas lines but mine is like yours. It is a 9.9 from oct 2016. Thanks
MMB nice, i have a mercury 102cc 2003, cannot find the fuel pump replacement, any idea where should i look
thanks
Thanks for the video... do you have a link to where I can order the O-ring? Can't seem to find it anywhere
where do you typically source your parts? I have the exact same motor that I'm trying to get running after sitting up for a couple years.

Fuel pump gasket. Pull full pump out. Should see a circular rubber ring. Replace it.
@@MaineManBassing thank you, your help is well appreciated

Craiglist moter i just looked at was squirting fuel when primed, needs this
Could also be the hoses.
If the oil grommet is not replaced or damaged would this cause oil to leak? First time boat owner here
yes. the o ring is a seal to prevent oil loss.
@@flysubcompact Thank you for the response, I really appreciate it, replaced and my merc is good to go👍🏾
The fuel pump is not electrified?
@@matthewsoto8114 not for a 9.9
Thanks !!!!
I have a 2010 9.9 do you know the part number for the impeller?
Should just be able to find one on Amazon
Where did you find this fuel pump and home much was it.
Online parts catalog. Had to order it through met dealer. Not $80 I think
is a 4 / 5 hp, small outboard
Don't do this at the dock with chest waders on LOL!
This video was garbage. U showed how to take it off how do u remove the diaphragm.
Lol that’s how you replace it. What did you expect?
Turn diaphragm 1/4 turn and it comes apart. Be careful as the button and a spring is under there.
