Replacing the internal anodes on a Yamaha F60 outboard

[@tnth9099]

thanks for posting - need to do this on my f60 asap!

[@damodoesall6240]

Please do!

Thanks for the video. I didn't even know there were internal anodes until I viewed your video. My friends were equally shocked. I have a 50HP motor that has always been run in fresh (unsalted) water in Michigan, USA. Do the anodes wear in fresh water? The motor has almost 400 hours. When I pull them if they are OK, can I stick it back in? Am I being foolishly cheap by attempting to do so?

[@damodoesall6240]

Yes, freshwater will last but not forever. I would not re use them unless they are in very good condition, they just go crumbly and then block the passages inside the head thus blocking cooling water flow.

gday mate i am just about to purchase my first 4 stroke yamaha 40hp this is a good video to learn from ,i know you can get external anodes aftermarket but not to many sell internal ones ,just trying to learn about as much as i can before i get this new engine soi have got some idea only had two strokes before

[@damodoesall6240]

Yeah, I use almost all genuine parts. I have found the Penrite10W-30 marine oil and the Ryco Z436 oil filter to work perfectly as well. Hint, try eBay for massive savings on genuine parts !!

@@damodoesall6240 I wish i had known the ryco number about a week ago just ordered 2 yamaha filters but got them at a good price i use penrite oil in all my vehicles im the penrite poster boy support an australian company , my twostroke my bike and my car have all the greases just bought 2 new cartriges of marine grease for the gun , seen anodes on a genuine site but the air freight is a killer from japan .

Gday mate thought i would pass this on to you but i have found there i a anode under the plastic cowling in the mid section on my 2021 40ho it is the same as yours a pencil anode same seal same lock washer ect might pay to have a look and see if your has one there as well all the best .

[@damodoesall6240]

Yes, there is always the extra one to protect the block.

Hello, I have a problem. I started to change the anodes of my yamaha F60 four stroke 2005 engine and of the 5 4 they broke, removing them from how bad they were and the part of the anode that goes into the engine the pieces remained inside and I have no way to remove them since They fell inside and cannot be seen. What I can do ? It's no problem that they stay inside, does it affect the engine?

[@damodoesall6240]

If it blocks a galley, your stuffed. Try to flush out with water or compressed air from alternate directions.

[@niloacevedo2022]

@damodoesall6240 Ok thanks if it doesn't work would I have to remove the block cover?

[@alanmckenzie3228]

Thank you for the tutorial. I have the F70 yamaha; I'm pretty sure there is also 4 internal anodes. Do you think that is true? again, thank you

[@damodoesall6240]

There are normally one per cylinder and one extra in the main gallery, easy way is to look for those special clips over the anodes on the side of the motor.

[@adamformby6679]

How many hours had that done since the anodes were last done?

[@damodoesall6240]

100 hours and 10 years, the previous owner did not use the boat much

[@crispernator]

day mate you said the bottom anode was bad and it broke of how did you get it out ?

[@damodoesall6240]

Pointy curved pliers, for the big bit, small hose taped to a vacuum cleaner nozzle for the crumbs.

@@damodoesall6240 thanks mate .

@@damodoesall6240 Gday mate just got the new motor home and i had tolook at the internal anodes ,well they are nothing like on your engine there a weird little thing held to the bole by a screw which i presume goes into the bolt ,i can see issues coming with this design as it is only a philips head screw got 4 of them saw something that looked like it on ebay and they want 16 dollars each for them and i dont even know if they are the correct ones ,no big rubber gasket just a small oring hmm is yamaha cheapn out?

[@crispernator]

@@damodoesall6240 Hi mate the anodes on the 40hp are different to yours ,they are really small and have a screw going through the anode into the bolt with a o ring on the bolt to seal it ( can see corossion problems already) ,from megazip schematics it seems these have been used for a long time lucky i didnt buy pencil anodes like yours .

[@davidplaza3233]

What happens if one breaks and is inside

[@damodoesall6240]

It blocks the passage way and your engine could overheat. Best to try and find it and remove it.

Hello there! I've got a crankcase cylinder anode for a 50hp yamaha outboard. Do you have a video or tips on replacing those? P/n: 6G8-11325-00.
