Are there internal anodes on a Honda BF 130

[puff tentacle]

I have only changed these anodes every season on my 2003 Honda 130 but I recently saw a thread on a forum indicating there are anodes under the cowling that may need changing. I can’t seem to find them on the internet anywhere. Can anyone clarify this.

I haven't seen specifically a 130 Honda, but on other Honda outboards I've not seen anodes under the cowling on some, just on the leg. Then on others, on both the leg, and under the cowl.

Go to boats.net and look up your motor then search for anodes. I took a guess at your serial number and it looks like here is at least one in the block, I didn't search further. Link below. My 1999 50HP does also, I'm guessing most Honda's probably do.

That was a good guess Matt, that’s my engine # range !!!
Oh boy , I have owned the boat for three years and haven’t changed any under the cowling. Thanks for the help

If it makes you feel any better, I've owned mine since 1999 and haven't changed any of them either. They still look fine. The one inside the cooling passages was caked up last time I had the carburetors off to clean them and I wasn't prepared to deal with a broken off screw at that time so I just chiseled it clean. My motor is used 99% in salt and it's starting to show some signs of built up so I'm debating on giving it a flush with a descaler, in which case I'll probably have to do something with the internal anodes as they don't do well with acids. I'm not looking forward to trying to break that screw free.. Old motors are like old people; sometimes the fix can be worse than the disease in regards to motor life. i.e. the motor might live happier longer with an old zinc than with a handful of broken off bolts.

Thanks Matt, that makes me feel somewhat better. Have a great season !
