Servicing Yamaha 4-strokes guide/help/advie

Hi everyone,

I've been asked to service a Yamaha F80 4 stroke outboard and would like a guide!

I am mechanically minded and now my stuff when it comes to boats and outboards but i've never serviced one and since its not mine - I dont want to get it wrong.

Thanks in advanced

Ur a better man than me.... I spent about 15mins on the yamaha site tryin to find that and all I could get was the flamin brochure lol.

Next question is which manual is the right one ?

As ive said previously, its not my engine and the engine isnt near me so cant get serial number etc. and the person who asked me to service it doesnt have a clue what year it is or for that matter the HP (its the family's mother im talking with).

But, Its a Four-stroke 80hp outboard and cant be more that 4 years old but when i scroll though the years i cant see a F80 anywhere ?

Also, Any proffesional marine engineers out there who have advice or a list of things to check/change/alter in the mean time !

Thanks again in advance !

Ok it's from 2002 but I bet it's the same engine - check to make sure.

Change oil - gear oil and impeller. Check/clean/adjust/change spark plugs.

probably about it. Oh and fuel filters of course. Check anodes.

Don't be daunted. Replacing an impeller is easy with the right tools
