O2 Sensor

[BASSMAN IA.]

I have a 2000 225 O66, does one need a special socket to remove O2 Sensor, and what is the best cleaning method. Thanks

Yamaha does make a special tool to remove it but you can remove the holder housing and clamp it in vise to remove sensor if you can't get it loose with wrench.

Ok, Thanks for the info.
