This video I replace the impeller on my Mercury 75 7.5 hp tiller style outboard. This was also a learning process for me as it was my first time so I share where I had issues and what to expect. Thanks for watching I hope this helps!

 Mercury Outboard 7.5 hp')){kind=link}
Hi, just watched your video, I’ve got a 1975 7.5 I inherited. The info will be really useful. Thanks for doing it.
Hi mate, I have the same engine, same year and everything. It came as an auxiliary engine on a boat I bought. It runs like a champ but I done seem to get full throttle. There is a lever on the back of the carb, if I pull that, it revs much harder. It looks like it should be connected to something. I'm wondering if I am missing some kind of linkage? Can you shed any light on it please? Cheers from Tasmania 🙂
My impellor wont come out slide up like yours did seems like it has a brass nut of some kind.
Thanks for the video, I'm doing this at the moment and I'm stuck trying to get the new impeller in place with the key. Even using grease I can't get it in. Can you share some more footage or do you have any other tips?
How many ounces of fuel mixture per gallon for 7.5 2 stroke Mercury
Where do you find parts for your 7.5 outboard Mercury I have one just like it
the exhaust is not in the tube you mentioned . its the water intake
Very helpful video. I noted that the nuts on both locations were nylock, I never reuse nylock. They dry out and wont hold, so pay a buck or two and use brand new ones.
Christ, the fins on the old impeller are all bent and hardened up and that exhaust tube you took off is the WATER tube grommet the water tube slides into.
where can I order online impeller and parts for older Mercury engines? Thank you
Good video, but it looked like it was in gear when the shift lever was in neutral when you were running it? just wondering if something moved when you put it back together ? is this something I should look out for when I do mine. thanks
Great runner! But u forgot to install the rubber band by the water pump seal and the top o-ring for the upper spine
one thing I've noticed in most videos. theres always something not explains that one maybe needing to find. for example putting it back together whether in forward or reverse position its said either or but then one will have a preference in reverse and will show you why. then never does. the dos and fonts of talking apart and what can happen is actually very important for a guy who does not do things often. and looks for that in a video almost step by sep with pics is great. I won't watch one that skips steps nor doesn't explain. sorry but not helpful in many ways with this video.
I am changing out mine but I cannot get the shift linkage to release, cannot pull down the lower unit. I did not see you do anything to release it. Help? Thx.
Housing to exit out the center of the prop.
The copper tube and new plastic piece are for water delivery to the powerhead, the exhaust flows outside of that down the lower
Thanks a mill, man! I just bought an awfully cheap one of these also with impeller issues, so I'm going to change it some time very soon following your instructions.
What size is the impeller? What website did you buy it off?
Thanks for the help.
Awesome video JB!! You made that look easy brother. She was purring like a kitten. It's hard to beat an older engine like that if you just take care of it! Take care man!!
