That woodruff key came out easier than I’ve ever seen.
Many thanks! I learned quite a bit from this, and I was a mechanic (motorcycles) for many years.
You did a great good and provided very nice details. I like your contents very much. Thank-you very much for sharing this.
Thank you for watching, and taking the time to leave such a nice comment.
Brilliant - thanks!
Thank you! X 100000000000000 Thank you!
day mate good video i wondered if you were going to say anything about the grease on the top of the shaft ,explained very well and a good tutorial .For me i would have changed the impellor even though as you say it was in good condition and given it to the customer as a spare ,i change my impellor every season regardless i had about 6 spares at one stage anyway good video .
We monitor the impellers very closely, and also have a very long history with all our customers, so we know how they use their boats. If I have the slightest doubt the impeller won't make the season it gets replaced. Our objective every spring is to ensure our customers have as reliable a boat as is possible.
@@CanadaWideMarine Just another quick question the grease your using on the bolts is that quicksilver assembly grease ? as i have a tub here and really dont know what to use it for after an engine was put back together
@@crispernator Any grease will do. The purpose off the grease is to seal the threads from water, thus preventing corrosion.
Hallo Sir, very good video. Can I ask what are u using for cleaning the shaft? Is that sand-paper? Thank you very much.
Have you ever heard a new impeller squeak(lightly) when newly installed? Is this normal? I did use silicon lubricant inside the impeller housing but not sure if i put any on the base plate. Yamaha F70.
Can that stand be purchased? I like the adjustability of it. Thanks
hello very instructive video thank you could you please give me the brand of your articulated ratchet cordially
I don't remember which one I use in this video, it could be an old Craftsman, as I have several of them, or it could be a Pro-tools.
@@CanadaWideMarine Hello sir thank you very much for taking the time to answer me, your videos are great very cordially
Very nice video! Question: my telltale does not have a stream of water at idle. Does that alone indicate that my water pump is not working? Also, does my 2012 F50LA motor have some sort of shutdown mechanism to protect itself if the water pump fails? Thank you. Jim
No Stream at idle can have many causes; a bad water pump impeller, restricted pickup, leakage between the pump and the motor, sticking pressure control valve or restriction in the supply to the telltale to name a few.
I don't know off the top of my head if your motor has a shutdown for overheat, (I work on hundreds of different makes and models, I can't keep track of every feature of every one), but I would advise to not rely on it even if you do have it. In our area the number one cause of catastrophic failure of outboard motors is overheating. The water pump impeller should be inspected every year. As a general guide we replace impellers on low usage motors (Less than 50 hrs per year) every 2 years, and every year if you use it more than 50 hours.
I can't get that EZE Slide Brake Lub in US. is the Super Lube 51004 Synthetic Oil with PTFE, High Viscosity do the same job?
According to their data sheet Super lube is not compatible with Natural rubber or EPDM. I do not know the exact composition of the impellers but natural rubber and EPDM are both very common in rubber products.
Try to find a rubber lubricant, or glycerin, or you can use good old dish soap, it works excellent and does not damage anything.
Why not just change the impellor while you are in there?
In this case I replaced this impeller last year, and the motor has less than ten hours on it since. Generally, because our customers put so few hours on their boats we replce the impeller every 2 years, inspect it every year, and we remove it for winter storage.
