Nice video… just a fyi, if you tilt the engine up and remove the drain plug, you can then lower it and let it drain. Saves a bit of a mess. ✌️
Thanks for the tip.
Nice video. Are your 3 anodes the same part number? Our F100hp (172 hours in 10 years) cylinder head corroded through to the water gallery (welded to repair at our cost) The original anodes (part number67F-01 no sign of wear) were replaced with 68V-01 anodes. I was told by my outboard motor mechanic it was a known problem by Yamaha.
I am sorry unable to say part number as sold that motor about 7 years ago. It is important to check every service and clean or replace the 3 internal anodes on the power head, 2 at the rear and 1 at the side. I understand the 80hp is a derated 100hp
Thanks one of the best videos I could find.
I have the same motor as yours (carby)
We just bought the boat and going over invoices, on the last one says that the gearbox seals will need replacing at the next service
Now I went to Yamaha and asked for seals and they give me some small o rings…
Can you please confirm what seals are required for the gearbox?
Thanks
I have to apologies about the late reply. I sold my 80 a few years back and now have a 115, I am unable to help you on this one. I do appreciate your comment, thanks.👍
Gday mate just revisiting this video ,i have just recieved my new 40hp and with all new toys you want to pull them apart and see how they work to a degree , i was looking at the anodes on the schematics for mine and noticed there was an anode underneath the plastic cowling just on the base below the motor .Now if you didnt look at the schematics you would never even know it was there and to be honest who ever takes the cowling off ,only when you need to remove the motor just thinking it might pay to have a look if you dont know about this anode and see if there is one under the cowling on your motor .
Thanks appreciate your sharing this. I now have a 115 Yamaha 4 stroke and finding ALL the anodes was not that easy, as there are quite a few.
I hope to do another vid on this a bit latter. I am sure 115 owners will appreciate knowing where they are. 👍
Excellent video 👌
Thanks for your comment. Appreciated.
Can you please tell me the numbers on your CDI? I have a 2001 90hp mercury and my CDI fried and the Yamaha CDI is 484$ and mercury one is 759$ but I’m only 90 percent sure they are the same due to them basically running the same engine those years… my mercury is identical to
Your but mercury stamps …. But I just need to know if factory part numbers are interchangeable
Sorry about very late reply. I have sold the 80 and now have a 115. and I am sorry cannot help you on that one.
Gday mate this is a really good video on showing how and what to check as routine maintenance ,this is the first one i have seen showing the actual anodes and what they do .Did you replace that really manky one ? I am about to take delivery of a 2022 40hp yamaha first four stroke and seeing yours has 700 hrs on it i rekon i have made a good choice you do relize the puritins will be having a fit " your not using genuine parts or oil your motor will be ruined " i say bollocks to them i use penrite oil in my vehicles and will use it the yamaha done all my own servicing since i was 16 now 63 never had a problem again this is a great video for teaching .
Appreciate your comments. Did I replace manky anode...no. There was still life in it. I do clean them up though as they work better. I think from memory I replaced them at 1000 hours. I eventually sold the 80 (still not missing a beat) and now have a 115 four stroke. The anodes are more trickier to find so will do another vid on servicing the 115. With the oils I believe its important to stick to either mineral or synthetic not to change them about. So I am lead to believe. Have fun with your new motor👍
My memory failed me I replaced anodes at 700 hrs
@@ufish2190 I have to say that is one of the cleanest best looked after engines for its age i have seen ,some you look at people have more money than brains or just dont care my last engine was a enduro over 10 years old but looked like brand new the guys eyes nearly popped out of his head when he saw it .
Thanks. I agree. These motors are not cheap
Hello sir could you please tell us what is the extra item under the back of the boat is used for.?
I have the same sort of make and model as yours .it appears to be an extra flotation device .
Where can I find this item thankyou.
.
Hi. Yes it is for flotation.
These totally stabilize the boat at rest and is effective in lumpy seas lifting the rear end of the boat.
I made them. Obtain a block of foam, shape it, then fiberglass.
Silicon works wonders attaching them to boat however 2 stainless screws are used also.
What do you use as a lubricant protectant?
I use similar to a WD40 with Silicone.
