I always buy a rebuild kit. The complete kit for the motor im working on. I recommend this as the old plate is usually scored and the cup may be to. Always use marine grease in the cup when installing the impeller. This will ease insertion and help it seat and if you like to run it before you put it in the test tank it will help you not smoke the impeller. Smoking a new impeller in a ungreased cup only takes minutes and then you will be tearing it all apart again needlessly.
I enjoyed your video, I thought you were very thorough in describing each step of the installation but one step I did not understand is why you rotated the impellor clockwise when inserting it into the water pump housing. My 6 hp 1973 Johnson flywheel rotates clockwise looking down on the engine therefore I have to make sure the impellor is installed counter-clockwise (from the bottom view) so that the impellor ears are oriented properly. They should be pointing opposite to the direction of rotation.
I’m as I type this putting a 5” extension kit on my 1979 6hp so I’m replacing the whole water pump assembly while it’s apart. Before doing this when I ran the motor, the pee stream was pretty week. I noticed in your video that your impeller was oriented clockwise from underneath where mine was in the counter clockwise position when I took it apart. I don’t know if someone years before me installed it wrong or it was right and your video is wrong...LOL. Guess I’ll find out because I’m putting it back together the way you say in the video.
My rollpin seems to have sheered off. At least there is just a bit of the pin left in the hole. I can remove that but have no replacement. Can you tell me where I can order one? Thanks a lot, your video's are amongst the most usefull on youtube, they're awesome.

Twisting the impeller clockwise into the housing while you are holding it upside down will have the impeller in backward when it is installed on the motor. Sorry to have to dispute what you are telling other to do, but that is wrong. I have been doing this for more than 55 years and i know what I'm talking about. Put the impeller on the shaft first, lower the cup over it, press down gentle while turning the flywheel clockwise until the impeller is seated in the housing cup. Then lower the housing down over the impeller cup and bolt it down. Now the impeller is in correctly.
old pump worked fine but decided to change it out anyway,, now I have no water through the pee hole.. , tested pump in bucket with drill all fine there , wate tube is in pump housing as should be.. still nothing... thoughts???? as i said, was fine 3 days ago till i changed pump, Thanks ,Glenn
Did you make sure you put the impeller key back in? If not the driveshaft will spin but the impeller won’t. Also make sure you get the water pump housing under water when you test it (deep bucket)
The pin makes sure the driveshaft and the Impeller spin together. If you don’t have the pin the driveshaft will spin but the Impeller wont thereby not pumping water
Just bought a 1965 Johnson 6 horse with it not pumping water. Upon removing the lower unit I noticed I didn't have a roll pin in my drive shaft. Also when I removed the water pump housing there was no gasket just a metal plate. Do I need the roll pin? Do I need a gasket there since there wasn't one? Ty in advance
What exactaly does that roll pin do? Mine didn't have one in it but it had the hole for it...I ordered one and put it in it...but when I took it aparte again the pin was bent..
+sc91260 if you look here goo.gl/aKKGp5 it compresses the lower bearing seal spring. Why the 6 hp has a lower bearing seal spring and not the 9.5 motors, I am not sure. If you check out the reinstall video I show you the slot the pin passes through
+sc91260 I did a little more digging and found this statement "This pin is holding seal set, if you run the engine without this pin it can cause the upper seal to slide sideways and not seal. The seal keeps water from being sucked into the motor. It also seals the air/fuel mix for the bottom cylinder. It may not idle very well without that seal in place. And if you're running in salt, you'll certainly do some damage without the seal working properly."

- During re-assembly, rotate the propeller in the forward direction. Watch the driveshaft rotate, That will tell you which way the impeller rotates.

The rubber fins will orient themselves properly regardless. If they stayed in the counter clockwise form, it wouldn’t push water.

great video detailed really enjoy it have a question how long is the pin that you drove in the shaft near the top thanks
Thanks...ill try putting one in again.
+sc91260 I also read that it needs to be a stainless steel pin so it doesn't corrode, especially if you are in salt water
DO you need gasket sealer on the pump housing gasket or does it go on dry?

Check the 2:40 mark in the video for what I am talking about
hey man great videos ! my impeller is all rotten so I have to change it all...the pin on the shaft has gone too what does it actually do ?
oh read below...I still don't really understand but will look at replacing it !

You don’t have to have it but it does keep pressure on a seal that prevents water from getting up there

Greetings!!! tell me why there is no water from the hole in the exhaust ??? Motor 5 HP evinrud 1996 .What to look for???
Bad water pump Impeller
ibb.co/qsshmB9 from here
I have a evinrude 8 and my impeller is not spitting water, I took it out and it looks fine, could anything else besides the impeller be the problem?
Check the 2:40 mark in the video. Make sure you have not forgotten to install you impeller pump key and that if it’s there it’s engaging the impeller
rocket city motors I went ahead and replaced the impeller, cheap fix, motor is running fine now
Pin on top have to have pin? What is for?
Is there a replacement roll pin for a 1965 johnson 6hp on amazon? thanks
A local auto parts or hardware store should an assortment of pins. 👍

Unless that motor turns counter clockwise that old impeller is in backwards.
Mark Weaver should it go anti-clockwise in that metal case??
@@hobojoe9284 Well....the driveshaft turns clockwise.
Mark Weaver but then surely that means if you’re looking at the impeller from underneath it would be spinning counterclockwise
@@hobojoe9284 That's right.
the impeller seems to be installed in the wrong direction in the video
I do not understand the need for the roll pin at the upper end of the shaft.
What is a drahv shaft?
What does slahd mean?
Front sod, back sod??? There’s no grass on an outboard.
You’re right, there is no grass on an outboard
