Great video. I planned to change my impeller and was wondering how to disconnect the shift linkage and this video showed me exactly how to do it. One suggestion, use a little anti-seize on all bolts since you have two dissimilar metals, stainless bolts into aluminum housing. Will make getting the bolts out easier the next time, and lessen the chance of a bolt snapping off. Been there done that.
Since I'm not too knowledgeable on boat motors, I had to have my impeller replaced on Mercury 9.9 4 stroke. Also , the mechanic had to clear out debris from the water pick-up tube and replace the thermostat. $ 550 later, it runs like a top. Had no idea that these things had to be changed on a regular basis. Thanks for the info.
Great video. Just as a point of reference so as to know in terms of hours. You said you change it at the beginning of the season, so what is your guess-estimate of the number of hours you run in a season? I am asking just cause the impeller you took off was pretty beat up, so it must have run for a lot of hours. Thanks.
@@pucho513 can’t remember. I think so. Just try to connect linkage rod in neural trap and play around with it. If that doesn’t work, connect it in forward and see what happens. Just play around connecting the link rod with each gear. You should get it eventually.
I have a newbie question please. Is the water that pees out of the little hole on the side just to indicate that the cooling system is working, or is that actually the entire output of the cooling circuit? Also, does it flow even if the thermostat is closed because the engine is cold? I'm halfway through doing the job, waiting on parts, and I couldn't see anywhere else the water could escape (but I am new to outboard maintenance) thanks. Simon.
If you look near the prop, there should be a little vent looking thing. The water propeller spins off the drive shaft, regardless of the gear it’s in or if it’s in neutral. As it spins, it circulates water from that vent up the engine and out the piss hole to cool the engine. I believe some outboards have a water pump: a totally different system. Usually the smaller outboards have a water impeller tho. As for the thermostat, I believe as the engine warms up, it opens to allow more water through to cool the engine. Those things can seize closed or open. You can put it in boiling water and see if it opens. I remember looking at mine and it had debris in it keeping it open, possible not allowing the engine to warm up properly. If you don’t have water pissing out the hole at all times, either it’s not working or it’s clogged. This happened to me after I was fishing in really shallow mucky water. I used a thin Allen wrench to unclog it.
The 9.9 Merc 4 cycles have an accelerator pump, and each twist of the throttle floods the engine with a shot of gasoline. Don't flood the engine, with or without the engine running.
Great video, much help
Thanks a million, I have the exact motor (2007) your channel has showed me so much💪🏾💪🏾💪🏾💪🏾

Well done bro. Great video. Definitely subbed! 👍😊
Thank you for your help!
Thanks for the video.
Great video
Thanks 🙏🏼
that really helped me
Awesome video bro
Where you order it from? Great video man.
Thanks
Do you have a part number for this?

So I was running it out of the water trying to trouble shoot some things. But that was the original impeller, and it’s a 2016 model.
Also my local repar shop suggested I use a bucket to feed water, the earmuffs are not good
My tell tale does the same, I have mine in a 30 gallon trash can, it starts pretty strong but then it slows to a slow stream, any idea?
Great work, what should the adjustment be on the shift rod/linkage can't get into reverse after impeller was replaced (previous owner)
Can’t remember. Play around with the linkage rod and screw.
@@MaineManBassing thank you for response, reverse is all the way down on shift rod correct?

@@pucho513 unscrew the link. Put it in a different gear. Screw the link. Try again. You’ll get it.
@@MaineManBassing Thanks for all the help and suggestions I really appreciate it 💪🏾👍🏾

@@MaineManBassing Thank you very much for your answer sir. I'll try the allen wrench tip on my Merc 9.9. Good fishing. Simon.
Which direction do the impeller blade go????
clockwise, as is the crankshaft
Don't you put grease on the main shaft going into the engine head? I remember dealer did it. Also some grease into the impeller box...
he should. Grease on the main shaft prevents long term tear damage to it
@@eddiegordo3472 Dab of grease also helps the pin/woodruff key stay put while setting the impeller down.

Yeah. I got it running again. I think the best thing would have been to just replace the carb. It ran a lot better after I replaced the carb gasket.
You hands shake like my dads lol
that kind of shaking is just stress, weakness. its not harmful. Spontaneous shaking that stops when you "look at it" is dangerous.
Haha. I am an old man!
Could you send me the part number please
I don’t know it. You can get the serial number from the engine. It’s under the cowling on the top. Then look online at parts catalog.
