    My Honda 135 has 1350 hours and has been perfect the entire time, but I know eventually something will break. What components do you guys replace on high-hour outboards?

    Maintenance I've been doing:
    oil, filter
    gear lube
    thermostats
    impeller
    grease

    id replace , its bit expensive but totally worth it imo they are always a ticking time bomb I would ask a shop what the interval normally is but I would just do it.. but thats me haha Manual does state that adjustment is needed every 200hrs

    Anodes, but especially any internal ones.

    Internal Anode Metal
    BF35-BF225
    12155-ZV5-000

    Two each per engine. Located inside the water passages on both intake and exhaust side. Sacrificial anode metal protects the engine from corrosion.

    2 Anodes per side. Don’t need to replace the gaskets. They are reusable (wish I knew that before I ordered them)
