I have 700hrs on my 2013 DF175 Suizuki I decided to check the
Internal Anodes just for lack of anything better to do today. Wow all five were 75 to 80% gone. This motor has never seen Fresh water. I will start changing them @ 400hrs or so. The external zincs look great (I did order All new zincs Wink )

Just a FYI
Have a good one!! Mr. Green Wink

I have a Honda 150 with about the same hours and it's 10 years old. I changed the anodes (zincs) which I had done 5 years ago. This time I also decided to change the exhaust manifold internal anodes (2 ea.), which had been there since the motor was new. I took the old ones, which were not "used" at all, removed the exhaust residue from them and they look like new.

The new o-rings which I also ordered from boats.net where the correct ones according to their parts list, but wrong in actuality. I reused the old seals.

So it looks like every motor has its quirks. We learn as we go along.

On my thousand hour maintenance, done by my Yamaha mechanics last fall, the internal anodes were changed for the first time. They were 50 - 60 % still intact. Evidently they do not go away at the same rate as the external ones, maybe due to the fact that they only get exposed when the OB is running, vs when I am sitting in the water, occasionally in a marina where there is shore power around.

I change mine in my Suzuki 90A every 50 hrs./6 months.
Always used in saltwater and always rinsed after each use.
Anodes are about 1/3 gone with lots of crud around them.
Cheap insurance on an expensive motor.

I look at my inside zincs once a year about every 75-100 hours Living in SW Florida the salinity of the water and humidity of the air is a lot worse then the PNW or up North . Usually the zincs are about 50% gone after 1 year or so in SW Florida. On a f-115 yamaha there are 3 inside zincs with rubber gaskets really not to hard to get at. There is a plastic plate and then remove spark plugs to take a look at those also . This should be part of a good tuneup
1-Change water separator every 6 months or whenever needed
2-Change oil and lower unit oil every year or 50-100 hours
3-pull prop and check and relube shaft
4-check all zincs every year
5-check valve clearance every 500-600 hours
6-check spark plugs replace as necessary
This is what i will be doing right before St. John's Gathering

Colby your zincs should be where the yamahas are same block if it's 2001-2006 merc 115 four stroke and maybe even earlier merc motors . The blocks of 4 stroke mercs 50.60,75,90,115 and the 225 hp are all yamaha blocks so zincs should be same behind the spark plugs you will see 2 .On the rt side looking at engine from rear is one zinc .I usually put water in there to flush it out
From 2006 on merc and Yamaha had a divorce so no more yamaha blocks for Brunswick (merc) That's when merc started doing there verado 4 strokes Jim

It may not look so bad from the outside. The weight is the true telltale.
