The service manual for my 02 Yamaha F115 shows an anode located under the value cover. The boat is moored in a slip for the summer. I guess my question would be, is it worth pulling the value cover to inspect the anode or is this something that rarely needs replacing? Any help would be appreciated.

its not under the valve cover.
they are located behind the plastic spark plug cover between the plugs. -
Thanks Rodbolt, I'll check out the anode.Comment

if they have not been serviced regularly DONT jack with them now.Comment

Rodbolt, your advice is good enough for me, but I am curious why you say not to jack with them, aren't they important is saltwater use?Comment

I have a feeling they will break off and be a major pain to remove if you have not been pulling and replacing over the years.
Kind of grown into the motor, Just my thoughtsComment

Your are no doubt right, 99. But what worries me is that if the anode is shot, the block will begin to rot next.Comment

then remove them.
DO NOT attempt to remove the 10mm headed hex bolt.
remove the 12mm headed hex bolt that holds the anode holder to the block.
now we may have to make 2 "special" tools.
take two long thin standard screwdrivers.
lock the first 3/8 of an inch in a vise.
use oxy/acetylyne to make it glow at the vice jaws.
bend it 90*.
now you can use these tools to remove them thar stucked amnodes thingys.
then carefully clean the bore.
then lock the anode holder in a vise,carefully.
then grab the anode with vise grips and unthread the anode.
then and ONLY then attempt to remove the 10mm headed hex bolt.
use a good water proof grease,quicksilver special lube 101 is wonderful, to coat the new anode holder orings on reasssmbly.
I use gel seal on the 10mm headed hex bolt threads to keep the anodes from viberating off.
IF you attempt to remove that 10mm headed bolt first, odds are way above high you will twist the head off.Comment
